Can I use this alongside other actives in my routine?

Yes. Glycerin is the lead active here, and it is formulated to sit alongside the rest of a routine rather than replace it. Introduce any new step on its own for the first week or two before adding it next to another strong active, so it is easy to tell which product is responsible for any change. Once it is settled into the routine, it layers the way any other skincare formula in a Korean routine does.

How do I know this is authentic and not a US-reformulated version?

Check the box against the listing: an authentic Korean-market SKU carries Korean-primary packaging and an intact Korean-market batch code, not a US-only relabel. Numbuzin's Korean-market formulas are sourced specifically to preserve that, rather than substituted for the US-shelf version some retailers carry under the same name.

When in a routine should I use this skincare formula?

Use it as the routine step, AM and PM, worked into the wider routine. Placing a skincare formula out of order is the most common reason a Korean routine feels like it is not working, so keep this one at its own step rather than doubling it up with a product built for a different stage. Give it a few weeks at that placement before judging the result.

What does Niacinamide do in this formula?

Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

How it works

The panel on this mask names 58 forms of peptide rather than one: Pisum Sativum (Pea) Peptide, Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, Copper Tripeptide-1, Hexapeptide-9, Nonapeptide-1, Tripeptide-1, Acetyl Tetrapeptide-5, Acetyl Tetrapeptide-9, Acetyl Tetrapeptide-2, Acetyl Octapeptide-3, Acetyl Hexapeptide-1, Acetyl Pentapeptide-1, Alanine/Histidine/Lysine Polypeptide Copper HCL, Acetyl Dipeptide-1 Cetyl Ester, Biotinoyl Tripeptide-1, Dipeptide-4, Hexapeptide-11, Hexapeptide-12, Myristoyl Pentapeptide-17, Myristoyl Hexapeptide-16, Myristoyl Pentapeptide-4, Nicotinoyl Tripeptide-1, Nonapeptide-7, Nicotinoyl Tripeptide-35, Nicotinoyl Dipeptide-26, Nicotinoyl Dipeptide-23, Octapeptide-2, Palmitoyl Tripeptide-5, Palmitoyl Hexapeptide-12, Pentapeptide-13, Palmitoyl Tetrapeptide-10, Palmitoyl Tripeptide-38, Palmitoyl Tripeptide-29, Palmitoyl Tripeptide-8, Tetrapeptide-44, Tetrapeptide-30, Tripeptide-10 Citrulline, Tripeptide-32, Tripeptide-29, Dipeptide Diaminobutyroyl Benzylamide Diacetate, Arginine/Lysine Polypeptide, Acetyl Tetrapeptide-3, SH-Octapeptide-4, SH-Decapeptide-7, Palmitoyl Tetrapeptide-7, Oligopeptide-29, Oligopeptide-32, Sr-Oligopeptide-91 Clostridium Botulinum Polypeptide-1, SH-Oligopeptide-1, SH-Polypeptide-1, SH-Polypeptide-9, SH-Oligopeptide-2, SH-Polypeptide-11, SH-Polypeptide-3, Sh-Polypeptide-16, SH-Polypeptide-62. The peptide fraction of pea protein, cut short enough to dissolve and spread. It is a plant peptide used for the look of firmness. On this panel it sits alongside Niacinamide, Adenosine and Saccharomyces/Silicon Ferment. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

How to use

Use the NAD+ BIO Lifting-sil Full Face Mask after toner, in place of your serum step, in the evening.
Attach the top sheet to the upper part of the face. Attach the bottom sheet to the lower part of face and pull both sides of sheet over the ears. Remove the sheets and tap gently for a better absorption.
Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.

Ingredient list read from incidecoder.com on 30 August 2026.

109 of 111 explained

Water solvent: Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
Dipropylene Glycol humectant: Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
Cetyl Ethylhexanoate emollient: Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
Glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
Niacinamide active: Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Polyglyceryl-10 Stearate emulsifier: Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
1,2-Hexanediol humectant: 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
Hydrogenated Poly(C6-14 Olefin) emollient: Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.
Isopentyldiol solvent: Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
Glyceryl Stearate SE emulsifier: Glyceryl Stearate SE is the self-emulsifying grade, supplied with a little soap already built in so it can hold an emulsion with less help. It thickens and softens like the plain form.
Butylene Glycol humectant: Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
Neopentyl Glycol Diheptanoate emollient: Neopentyl Glycol Diheptanoate is a light ester emollient chosen for a dry, powdery finish. It also disperses pigment evenly.

97 more explained

Carbomer thickener: Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
Arginine amino acid: Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
Panthenol humectant: Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
Trehalose humectant: Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
Ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
Xanthan Gum thickener: Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
Adenosine active: Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
Sodium Polyacrylate thickener: Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
Disodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
Propanediol humectant: Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
Polylactic Acid film former: A polymer built from lactic acid, used as fine spheres or as a film. It scatters light softly and blurs the look of surface texture.
Polyglyceryl-10 Laurate emulsifier: Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
Saccharomyces/Silicon Ferment ferment: Yeast grown with silicon so the mineral is carried inside the cells. It is used as an organically bound source of silicon.
Saccharomyces/Copper Ferment ferment: Yeast grown in the presence of copper, so the mineral ends up bound inside the yeast. It is a way of delivering a trace mineral in an organic form.
Saccharomyces/Magnesium Ferment ferment: Yeast grown with magnesium so the mineral is bound into the ferment. It is used to supply a trace mineral in an organic form.
Saccharomyces/Iron Ferment ferment: Yeast grown with iron so the mineral is carried inside the cells. It is used as a trace mineral source in an organic form.
Saccharomyces/Zinc Ferment ferment: Yeast grown with zinc so the mineral ends up bound in the ferment. It is used to supply trace zinc in an organic form.
Polyglyceryl-6 Laurate emulsifier: Six glycerin units joined to lauric acid. Polyglyceryl esters are the mild, PEG-free way to hold oil and water together.
Caprylic/Capric Triglyceride emollient: Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
Hydrogenated Lecithin emulsifier: Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
Thioctic Acid antioxidant: Thioctic Acid is alpha lipoic acid, an antioxidant that dissolves in both water and oil, which is unusual. It is yellow and carries a faint sulfur smell.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
Adenosine Triphosphate active: Adenosine Triphosphate is the molecule cells move energy around with. In a formula it is a conditioning nucleotide, related to the adenosine declared beside it.
Nicotinamide Adenine Dinucleotide active: Nicotinamide Adenine Dinucleotide, usually written NAD, is a coenzyme every living cell carries, built from vitamin B3. In a formula it is used as a conditioning active at very low levels.
Nicotinamide Mononucleotide active: Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
Resveratrol antioxidant: Resveratrol is an antioxidant from grape skin and Japanese knotweed. It is used for the look of dullness and is often paired with ferulic acid, which keeps it stable.
Polyglyceryl-3 Methylglucose Distearate emulsifier: Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
Pullulan film former: Pullulan is a fermentation-derived polysaccharide that dries to a tight film, which is why it produces a temporary, visible tightening feel on the skin.
Ubiquinone antioxidant: Ubiquinone is coenzyme Q10, an antioxidant every cell uses in its own energy production. In a formula it is oil soluble, faintly yellow, and used for the look of tired, dull skin.
Sodium Palmitoyl Sarcosinate surfactant: Sodium Palmitoyl Sarcosinate is an amino-acid-derived cleanser built on sarcosine. It foams well at skin-friendly pH, which is why Korean low-pH cleansers use it.
Astaxanthin antioxidant: Astaxanthin is a deep red antioxidant from microalgae, the pigment that makes salmon pink. It is oil soluble, colours a formula noticeably, and is used as an antioxidant.
Pisum Sativum (Pea) Peptide peptide: The peptide fraction of pea protein, cut short enough to dissolve and spread. It is a plant peptide used for the look of firmness.
Acetyl Hexapeptide-8 peptide: Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
Palmitoyl Pentapeptide-4 peptide: Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
Palmitoyl Tripeptide-1 peptide: Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7.
Copper Tripeptide-1 peptide: Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
Hexapeptide-9 peptide: Hexapeptide-9 is a six-amino-acid peptide used for the look of firmness and elasticity. It is water soluble and appears in peptide blends rather than alone.
Nonapeptide-1 peptide: Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.
Tripeptide-1 peptide: Tripeptide-1 is the copper-free version of the classic three-amino-acid peptide. It is used for the look of firmness in formulas that avoid copper's blue tint.
Acetyl Tetrapeptide-5 peptide: Acetyl Tetrapeptide-5 is a four-amino-acid peptide used in eye products for the look of puffiness and crepiness.
Acetyl Tetrapeptide-9 peptide: Acetyl Tetrapeptide-9 is a four-amino-acid peptide used for the look of firmness and density. It is most often supplied alongside acetyl tetrapeptide-11.
Acetyl Tetrapeptide-2 peptide: Acetyl Tetrapeptide-2 is a four-amino-acid peptide used for the look of firmness, particularly in eye and neck formulas.
Acetyl Octapeptide-3 peptide: Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone.
Acetyl Hexapeptide-1 peptide: Acetyl Hexapeptide-1 is a six-amino-acid peptide used for the look of even tone. It is one of the few peptides aimed at pigment rather than at lines.
Alanine/Histidine/Lysine Polypeptide Copper HCL peptide: This is a three-amino-acid peptide bound to copper and supplied as a hydrochloride salt. Copper peptides are blue in solution, which is often why a serum carrying one is tinted.
Acetyl Dipeptide-1 Cetyl Ester peptide: Acetyl Dipeptide-1 Cetyl Ester is a two-amino-acid peptide with a fatty cetyl tail attached, which lets it sit in the oil phase of a formula rather than only the water phase.
Biotinoyl Tripeptide-1 peptide: A three-amino-acid peptide joined to biotin, vitamin B7. It is the peptide most used in lash, brow and scalp formulas.
Dipeptide-4 peptide: Dipeptide-4 is a two-amino-acid peptide. It is water soluble and appears as one component of a multi-peptide blend rather than on its own.
Hexapeptide-11 peptide: Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
Hexapeptide-12 peptide: Hexapeptide-12 is a six-amino-acid peptide used for the look of fine lines. It is water soluble and is usually paired with longer peptides in a blend.
Myristoyl Pentapeptide-17 peptide: A five-amino-acid peptide with a myristic acid tail. It is the peptide used in lash and brow formulas for the look of fuller hair.
Myristoyl Hexapeptide-16 peptide: A six-amino-acid peptide with a fatty myristoyl tail. It is used in lash and brow formulas for the look of fuller hair.
Myristoyl Pentapeptide-4 peptide: A five-amino-acid peptide carrying a fatty myristoyl tail so it can sit in the oil phase. It is used as a conditioning peptide.
Nicotinoyl Tripeptide-1 peptide: A three-amino-acid peptide joined to a vitamin B3 group. It is used as a conditioning peptide, most often in scalp and lash products.
Nonapeptide-7 peptide: Nonapeptide-7 is a nine-amino-acid peptide. Nonapeptides are among the longer synthetic cosmetic peptides and appear in blends rather than alone.
Nicotinoyl Tripeptide-35 peptide: Nicotinoyl Tripeptide-35 is a three-amino-acid peptide carrying a nicotinoyl group, the same chemical family as niacinamide. It is used in blends rather than alone.
Nicotinoyl Dipeptide-26 peptide: A two-amino-acid peptide joined to a vitamin B3 group. It is used for the look of uneven tone and enlarged pores.
Nicotinoyl Dipeptide-23 peptide: A two-amino-acid peptide carrying a vitamin B3 group. It is used as a conditioning peptide, usually beside niacinamide itself.
Octapeptide-2 peptide: An eight-amino-acid peptide used as a conditioning peptide for the look of firmness.
Palmitoyl Tripeptide-5 peptide: Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
Palmitoyl Hexapeptide-12 peptide: Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend.
Pentapeptide-13 peptide: A five-amino-acid peptide used as a conditioning peptide, generally within a blend.
Palmitoyl Tetrapeptide-10 peptide: A four-amino-acid peptide carrying a fatty palmitoyl tail. It is used as a conditioning peptide, usually beside other palmitoyl peptides.
Palmitoyl Tripeptide-38 peptide: A three-amino-acid peptide with a fatty palmitoyl tail, sold as Matrixyl Synthe-6. It is used for the look of fine lines and surface texture.
Palmitoyl Tripeptide-29 peptide: Palmitoyl Tripeptide-29 is the collagen-fragment tripeptide with a fatty tail attached. The tail is what lets a water-loving peptide cross an oily surface.
Palmitoyl Tripeptide-8 peptide: A three-amino-acid peptide with a palmitic acid tail, which lets it sit in the oil phase. It is used for the look of reddened, reactive skin.
Tetrapeptide-44 peptide: A four-amino-acid peptide used as a conditioning peptide, most often in blends aimed at the look of firmness.
Tetrapeptide-30 peptide: A four-amino-acid peptide used for the look of uneven tone, generally within a peptide blend rather than on its own.
Tripeptide-10 Citrulline peptide: A three-amino-acid peptide joined to citrulline. It is used for the look of firmness and is often paired with palmitoyl tripeptide-5.
Tripeptide-32 peptide: A three-amino-acid peptide used as a conditioning peptide within a wider complex.
Tripeptide-29 peptide: Tripeptide-29 is a three-amino-acid peptide whose sequence repeats a fragment of the collagen molecule itself. It is used in blends aimed at the look of firmness.
Caprylyl Glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
Dipeptide Diaminobutyroyl Benzylamide Diacetate peptide: This is a two-amino-acid peptide, sold as Syn-Ake, used for the look of expression lines. Its structure was modelled on a component of snake venom, though nothing of the venom itself is in it.
Arginine/Lysine Polypeptide peptide: A polypeptide built from the amino acids arginine and lysine. It holds water strongly and leaves a smoothing film.
Dextran polysaccharide: Dextran is a branched sugar polymer made by fermenting sucrose. It holds water, thickens slightly, and is used as a carrier that keeps other water-soluble ingredients evenly spread.
Hydrolyzed Elastin protein: Hydrolyzed Elastin is fragments of elastin, the protein that gives skin its snap back. Like collagen it cannot rebuild the real thing from the outside; it holds water and leaves a smooth film.
Soluble Collagen protein: Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
Acetyl Tetrapeptide-3 peptide: Acetyl Tetrapeptide-3 is a four-amino-acid peptide used for the look of density and firmness. It appears in scalp formulas as often as in facial ones.
Trifolium Pratense (Clover) Flower Extract plant extract: Red clover flower extract, carrying isoflavones. It is used as a conditioning plant extract.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
Mannose sugar: Mannose is a simple sugar closely related to glucose. It is used as a humectant and as a building block in the polysaccharide blends that hold water on the surface.
SH-Octapeptide-4 peptide: An eight-amino-acid peptide produced by fermentation. It is used as a conditioning peptide inside a wider peptide complex.
SH-Decapeptide-7 peptide: A ten-amino-acid peptide made by fermentation. It is used as a conditioning peptide, usually within a blend.
Collagen protein: Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former.
Elastin protein: Elastin is the stretchy structural protein that sits alongside collagen in the dermis. It cannot enter skin from the outside, so in a formula it is a water-holding, film-forming protein.
Glutathione antioxidant: Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
Palmitoyl Tetrapeptide-7 peptide: Palmitoyl Tetrapeptide-7 is a four-amino-acid peptide with a fatty tail, used for the look of fine lines. With palmitoyl tripeptide-1 it forms the pairing sold as Matrixyl 3000.
Oligopeptide-29 peptide: A short chain of amino acids used as a conditioning peptide. Oligopeptide numbers are registry entries, not strengths.
Oligopeptide-32 peptide: A short amino acid chain used as a conditioning peptide, usually one of several oligopeptides declared together.
SH-Oligopeptide-1 peptide: sh-Oligopeptide-1 is a peptide made by yeast fermentation rather than synthesis, which is what the sh prefix records. It is used for the look of firmness and skin recovery after irritation.
SH-Polypeptide-1 peptide: sh-Polypeptide-1 is a longer fermentation-produced peptide. It is used in formulas built around the look of resilience and recovery.
SH-Polypeptide-9 peptide: sh-Polypeptide-9 is another fermentation-produced peptide used for the look of firmness, usually as part of a blend.
SH-Oligopeptide-2 peptide: sh-Oligopeptide-2 is a second fermentation-produced peptide, used alongside sh-oligopeptide-1 for the look of firmness.
SH-Polypeptide-11 peptide: sh-Polypeptide-11 is a fermentation-produced peptide. Korean formulas use the sh family in blends built around the look of resilience and recovery.
SH-Polypeptide-3 peptide: sh-Polypeptide-3 is a peptide made by fermentation rather than by chemical synthesis, which is what the sh prefix records. Polypeptide means a longer chain than a tri or hexapeptide.
Sh-Polypeptide-16 peptide: A polypeptide made by fermentation rather than extracted, which is what the sh prefix records. It is used as a conditioning peptide.
SH-Polypeptide-62 peptide: A fermentation-produced polypeptide, the sh prefix marking that it is grown in a microbe rather than taken from tissue. It is used as a conditioning peptide.
