How it works
Urea leads the ingredient panel on this serum. Urea is one of the substances skin makes to hold its own water, part of the natural moisturising factor. At low levels it hydrates; at high levels it also softens hard, thickened skin. On this panel it sits alongside Adenosine, Acetyl Hexapeptide-8 and Copper Tripeptide-1. 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.

Inside the formula
Inside the formula
What is Shaishaishai Repair Milky Urea Glow Bubble Serum for?
It is a serum in Shaishaishai's Korean-market lineup. After toner, AM and/or PM. Press or smooth over the face and let it settle before the next step. What ships is the same Korean-market formula and packaging Shaishaishai sells at home, not a US-reformulated version.
Where does this go in a routine, and how do I use it?
After toner, AM and/or PM. Press or smooth over the face and let it settle before the next step. It takes the step after toner and before moisturizer of a Korean-style layering routine. Give it a minute to settle before adding the next product on top.
Is this the authentic Korean-market version, not a US retail reformulation?
Yes. What we ship is Shaishaishai's Korean-market formula and packaging, sourced for the Korean market rather than a US-facing reformulation. The intact Korean barcode and batch code on the box are part of that proof.
Who is this product best suited for?
Normal, Combination and Dry skin types are the best fit, based on what this product type is generally formulated for. Patch test first, as with any new addition to a routine.

42 of 49 explained
- Purified 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.
- Cyclopentasiloxane silicone
- Cyclopentasiloxane is a volatile silicone: it spreads a formula thin and smooth then evaporates, leaving no residue. It is the silicone behind a dry, powdery primer finish.
- 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.
- Urea humectant
- Urea is one of the substances skin makes to hold its own water, part of the natural moisturising factor. At low levels it hydrates; at high levels it also softens hard, thickened skin.
- Di-C12-13 Alkyl Malate emollient
- A malic acid ester with two medium chain alcohols. It is a light, tacky emollient often used to wet pigments and to hold colour in place.
- Diisostearyl Malate emollient
- Diisostearyl Malate is a thick, glossy ester used to hold pigment in suspension and give a cushioned shine. It is the standard emollient in lip products.
- 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.
- 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.
- 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.
- Dimethicone silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- Polyglyceryl-6 Polyricinoleate emulsifier
- A castor-derived polyglycerin emulsifier for water-in-oil systems, where water droplets have to stay suspended inside an oil phase.
- PEG-10 Dimethicone silicone
- PEG-10 Dimethicone is a silicone with a water-loving chain attached, so it bridges the silicone and water phases. It is used as an emulsifier and to give a light, silky feel.
30 more explained
- Cyclohexasiloxane silicone
- Cyclohexasiloxane is a volatile silicone used for a light, fast-spreading feel that leaves nothing behind.
- 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.
- 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.
- 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.
- 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.
- 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.
- Ferulic Acid antioxidant
- Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
- Beta-Glucan polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Glyceryl Glucoside humectant
- Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
- 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.
- 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.
- Scutellaria Baicalensis Root Extract plant extract
- Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
- Shea Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- Propylene Carbonate solvent
- A polar solvent used mainly with clays: it swells montmorillonite and hectorite so they thicken an oil phase. It also thins heavy pigment pastes.
- 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.
- 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.
- 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.
- 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.
- Caprylhydroxamic Acid preservative booster
- A chelator that works by denying microbes the iron they need, which lets a formula hold at a skin-friendly pH with less conventional preservative.
- Disteardimonium Hectorite thickener
- Disteardimonium Hectorite is a modified clay used to thicken the oil phase and stop pigments settling to the bottom of the bottle.
- Fragrance fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- Benzyl Benzoate fragrance component
- Benzyl Benzoate is a faintly balsamic aromatic that also acts as a fixative, holding a fragrance on skin longer. It is one of the 26 declarable fragrance components.
- Benzyl Salicylate fragrance component
- Benzyl Salicylate is a faint floral aromatic that also holds a fragrance on skin longer. It is one of the 26 fragrance components EU labelling requires to be named.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Hexyl Cinnamal fragrance component
- Hexyl Cinnamal is a jasmine-like aromatic. It is one of the 26 fragrance components EU labelling requires to be named individually.
- Butylphenyl Methylpropional fragrance component
- A synthetic aroma molecule with a soft floral note, once widely known as Lilial. It is one of the fragrance components EU labelling requires to be named separately.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

How to use
- Use the Repair Milky Urea Glow Bubble Serum after toner and before moisturizer, morning and evening.
- Always shake well to thoroughly mix the cream and water layers. Apply a moderate amount to the skin along the skin texture and blend gently for absorption.
- Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top.
- Twice a day, every day. Do not stack it with a second serum of the same kind; two hydrating serums in one routine do the work of one.
Worth knowing
- Patch test on the inner arm 24 hours before adding this to your face or scalp, as with any new product.
