How it works
The panel on this lotion names twelve forms of peptide rather than one: Hexapeptide-11, Oligopeptide-1, Oligopeptide-2, Oligopeptide-3, Acetyl Hexapeptide-8, Avena Sativa (Oat) Peptide, Copper Tripeptide-1, Palmitoyl Hexapeptide-12, Palmitoyl Pentapeptide-4, Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1, Tripeptide-1. Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness. On this panel it sits alongside Coptis Japonica Root Extract, Ceramide NP and Hydrolyzed Collagen. Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
Key benefits
- Twelve forms of peptide on one panel, not a single token inclusion

Inside the formula
Inside the formula
When should I apply Skin Barrier Calming Lotion Barrier Care & Boost Glow, morning, night, or both?
This is formulated for both, as the last step of a standard AM and PM routine after serum or essence. Morning use seals in hydration under SPF and makeup; night use works while skin is in its natural overnight recovery cycle. Most people get the fullest benefit using it consistently at both times rather than just one.
How much Skin Barrier Calming Lotion Barrier Care & Boost Glow should I use per application?
A dime- to nickel-sized amount is enough for the whole face for most people; press it in rather than rubbing hard. Very dry skin or a cold, dry climate may need slightly more, especially at night. Using more than that mostly sits on the surface rather than absorbing any faster.
Will Skin Barrier Calming Lotion Barrier Care & Boost Glow feel too heavy or greasy for oily skin?
The finish depends on the specific formula, but a moisturizer's job either way is to seal in the hydration from earlier steps rather than add oil on its own. Oily or combination skin can apply a thinner layer or focus it on drier areas of the face rather than skipping moisturizer entirely. Skipping a moisturizer step usually increases oil production rather than reducing it, since skin overcompensates for the moisture loss.
Can Skin Barrier Calming Lotion Barrier Care & Boost Glow be used under makeup?
Yes, apply it as the last skincare step and give it a minute or two to settle before starting makeup, since applying foundation over a still-wet cream is what usually causes pilling. If a formula still feels tacky after a couple of minutes, a lighter layer next time will resolve that. It should not interfere with SPF or makeup once it has absorbed.
Is Skin Barrier Calming Lotion Barrier Care & Boost Glow the authentic Korean-market formula?
Yes, this is the same moisturizer ongredients sells through Korean retail, sourced specifically for Korean Pharmacy's US catalog rather than reformulated for a US shelf. and its original Korean-market batch coding intact. That is the version this brand is actually known for.

Ingredient list read from incidecoder.com on 30 August 2026.
59 of 59 explained
- Water(Aqua) 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Phenyl Trimethicone silicone
- Phenyl Trimethicone is a silicone with a higher refractive index than most, so it adds visible gloss as well as slip. It is common in glow and lip textures.
- 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.
- Polysorbate 60 emulsifier
- Polysorbate 60 is a water-loving emulsifier used with a fatty co-emulsifier to build stable lotions and creams.
- 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.
- 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.
- Hydroxyethyl Urea humectant
- Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
47 more explained
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- 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.
- Simmondsia Chinensis (Jojoba) Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- 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.
- Candida Bombicola/Glucose/Methyl Rapeseedate Ferment ferment
- This ferment produces sophorolipids, sugar-based molecules that behave as very mild surfactants and emulsifiers. It is used to keep a formula blended without a harsh cleanser.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- 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.
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- 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.
- 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.
- Pentylene Glycol humectant
- Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
- Ethoxydiglycol solvent
- Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
- Lecithin emulsifier
- Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- Acetyl Glutamine amino acid
- Glutamine with an acetyl group added, which makes it more stable in water. It is used as a conditioning amino acid.
- Borago Officinalis Extract plant extract
- Borage extract. The plant is best known for the gamma-linolenic acid in its seed oil, while the water extract carries mucilage that holds water at the surface.
- Corchorus Olitorius Leaf Extract plant extract
- Jute mallow leaf extract. The leaf is notably mucilaginous, so the extract holds water and gives a slippery feel.
- Daucus Carota Sativa (Carrot) Root Extract plant extract
- Carrot Root Extract carries carotenoids, which give it a strong orange colour. It is used as an antioxidant extract and can tint a formula.
- Ilex Paraguariensis Leaf Extract plant extract
- Yerba mate leaf extract, carrying caffeine and polyphenols. It is used as a plant antioxidant, most often in eye formulas.
- Madecassoside active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
- Pantothenic Acid vitamin
- Pantothenic Acid is vitamin B5, the form skin converts panthenol into. It is used as a conditioning humectant that leaves skin feeling soft rather than tight.
- Decyl Glucoside surfactant
- Decyl Glucoside is a sugar and coconut-derived surfactant, one of the mildest cleansers available. It produces a soft, low foam and rinses without stripping.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Bacillus/Soybean Ferment Extract ferment
- This is soybean fermented by Bacillus, the process behind Korean cheonggukjang. Fermentation cuts the soy proteins into smaller pieces and produces polyglutamic acid, a strong humectant.
- Asiatic Acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- 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.
- Madecassic Acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
- Polyglutamic Acid humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- Xylose sugar
- Xylose is a simple wood sugar. It is a humectant, and it is the unit the xylitol-based hydration blends are built from.
- Folic Acid vitamin
- Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend.
- Centella Asiatica Extract plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- Hexapeptide-11 peptide
- Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
- Oligopeptide-1 peptide
- Oligopeptide-1 is a short synthetic peptide. Oligo means the chain is short without the name fixing its length, which is why oligopeptides appear in blends where several sequences work together.
- Oligopeptide-2 peptide
- Oligopeptide-2 is a short synthetic peptide, water soluble like most of the unmodified oligopeptides. It is supplied as one component of a blend.
- Oligopeptide-3 peptide
- Oligopeptide-3 is another short synthetic peptide sequence. Numbered oligopeptides that sit next to each other on a label are separate sequences, not doses of one ingredient.
- 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.
- Avena Sativa (Oat) Peptide peptide
- Avena Sativa Peptide is oat protein cut into short fragments. Plant peptides behave as water-holding, film-forming proteins rather than as the signalling peptides of the numbered families.
- 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.
- 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.
- 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 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.
- 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.
- 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.

How to use
- Use the Skin Barrier Calming Lotion Barrier Care & Boost Glow as the last skincare step, morning and evening, over serum.
- Apply the ongredients Calming Lotion EX twice daily, at the final step in your morning and evening skin care routines. Take an appropriate amount and gently massage it into your face. Lightly tap skin to aid absorption. If your skin needs extra hydration, layer the lotion two or three times for more intense moisturizing and calming care.
- Serum first, this second, then sunscreen in the morning. On dry skin a richer cream can go over it at night.
- Twice a day. Do not decant it into a smaller jar to travel with; an emulsion in a pump is packaged that way to keep it stable.
Worth knowing
- Pregnant or breastfeeding shoppers should run any new skincare step past their own physician before adding it.
- This step is not a substitute for a dedicated sunscreen, which should still be the last step of the morning routine.
- New actives, including this one, are best patch tested on the inner arm before a first full-face use.
