How it works
The Retinol Super Bounce Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Retinol, named thirty-third on its own ingredient list. The same list carries Madecassoside, Hydroxypinacolone Retinoate and Acetyl Tetrapeptide-11, so the active is not the only thing on it worth naming. How much of the Retinol stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum IOPE sells in Korea, Retinol and all.

Inside the formula
Inside the formula
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Retinol and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Retinol and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Retinol?
Madecassoside, Hydroxypinacolone Retinoate and Acetyl Tetrapeptide-11. The order they are printed in on this serum's panel is the order on the box, so you can see where Retinol sits relative to them. Further down the same panel: Decapeptide-4, sh-Oligopeptide-1 and Lactobacillus Ferment Lysate.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

39 of 45 explained
- 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.
- 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.
- Squalane emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- Methyl Trimethicone silicone
- Methyl Trimethicone is a light, volatile silicone chosen for a notably dry finish. It thins a formula and disperses powders 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.
- Bis-Hydroxyethoxypropyl Dimethicone silicone
- A silicone carrying water friendly alcohol groups at both ends, so it mixes into water based formulas more readily than plain dimethicone. It is used as a conditioning silicone and a co-emulsifier.
- 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.
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
- C14-22 Alcohols fatty alcohol
- C14-22 Alcohols is a declaration for a mixture of long-chain fatty alcohols. They thicken a cream and hold the emulsion together.
- Butyrospermum Parkii (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.
- Palmitic Acid fatty acid
- Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
- Stearic Acid fatty acid
- Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
27 more explained
- Glyceryl Stearate emulsifier
- Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
- PEG-100 Stearate emulsifier
- PEG-100 Stearate is a water-loving emulsifier almost always paired with glyceryl stearate. Together they form the standard cream base of the last fifty years.
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
- Dimethyl Isosorbide solvent
- Dimethyl Isosorbide is a solvent used to dissolve actives that water and oil both reject, and to carry them evenly through the outer layer of skin. It appears in vitamin C and retinoid formulas for exactly that reason.
- C12-20 Alkyl Glucoside emulsifier
- C12-20 Alkyl Glucoside is a sugar-derived emulsifier used in mild, plant-based cream bases.
- Glycine Soja (Soybean) Oil emollient
- Soybean Oil is a linoleic-rich plant oil used as an emollient. It also carries soy phytosterols and vitamin E.
- 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.
- Mannitol humectant
- Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
- Daucus Carota Sativa 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.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hydroxypinacolone Retinoate active
- Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings.
- Sorbitan Isostearate emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- Retinol (509 Iu/G) active
- Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
- 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.
- Beta-Carotene antioxidant
- Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
- 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.
- Acetyl Tetrapeptide-11 peptide
- Acetyl Tetrapeptide-11 is a four-amino-acid peptide used for the look of firmness, and it is the usual partner to acetyl tetrapeptide-9.
- Hydrogenated Phosphatidylcholine emulsifier
- Hydrogenated Phosphatidylcholine is the stabilised form of the main lecithin phospholipid. It builds the liposome shells that hold an active together in a formula.
- Chamaecyparis Obtusa Leaf Extract plant extract
- Chamaecyparis Obtusa is hinoki cypress. Its leaf extract carries aromatic plant compounds and is used in Korean formulas aimed at oily, congested skin.
- Decapeptide-4 peptide
- Decapeptide-4 is a ten-amino-acid peptide, longer than most cosmetic peptides. Length changes how a peptide behaves in a formula, not how strong it is.
- Sodium Oleate surfactant
- Sodium Oleate is the soap made from oleic acid. It cleanses and foams, and it is what a cleansing balm turns into when the oil phase is saponified.
