How it works
The Intensive Perfect Anti-Aging Program is a 15ml product. The active it is built around is Allantoin, named tenth on its own ingredient list. The same list carries Adenosine, Palmitoyl Tripeptide-5 and Calendula Officinalis Flower Extract, so the active is not the only thing on it worth naming. How much of the Allantoin stays on the skin, and for how long, is decided by the product format rather than by the list alone. This is the Original Korean Formula, the product isoi sells in Korea, Allantoin and all.
Key benefits
- Allantoin, the active this product is built around
- Adenosine on the same list, an active
- Palmitoyl Tripeptide-5 on the same list, a peptide
- Calendula Officinalis Flower Extract and Coptis Japonica Root Extract on the same list, plant extracts
- Castanea Crenata (Chestnut) Shell Extract and Malpighia Glabra (Acerola) Fruit Extract further down the same list
- Corchorus Olitorius Leaf Extract and Brassica Oleracea Italica (Broccoli) Extract further down the same list
How to use
- Apply as the last step of your routine, morning and night, smoothing over the face and neck until absorbed.
Is this the Korean-market product or a US version?
The Korean-market one, Allantoin and all. We match this product to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this product contain fragrance?
Yes. The ingredient list names Citronellol, Eugenol, Farnesol and Geraniol. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this product is not the one.
What else is on the list besides Allantoin?
Adenosine, Palmitoyl Tripeptide-5 and Calendula Officinalis Flower Extract. The order they are printed in on this product's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Coptis Japonica Root Extract, Castanea Crenata (Chestnut) Shell Extract and Malpighia Glabra (Acerola) Fruit Extract.
Not on the ingredient list below: fragrance or parfum, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

32 of 34 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.
- 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.
- Alcohol Denat solvent
- Alcohol Denat. is ethanol with a bitter additive that makes it undrinkable, which is a tax rule rather than a formulation choice. It behaves like alcohol: a fast-evaporating solvent that gives a weightless finish and can feel drying at higher levels.
- 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.
- 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.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Olea Europaea (Olive) Fruit Oil emollient
- Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
- 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.
- 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.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- 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.
- 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.
20 more explained
- 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.
- 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.
- Calendula Officinalis (Pot Marigold) Flower Extract plant extract
- Marigold flower extract, one of the oldest plant ingredients used for the look of reddened, easily bothered skin. It carries carotenoids and flavonoids.
- 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.
- Rosa Damascena Flower Oil fragrance component
- Rosa Damascena Flower Oil is rose essential oil, one of the most expensive materials in perfumery. It scents a formula, and like every essential oil it is a class reactive skin often does not tolerate.
- Castanea Crenata Shell Extract plant extract
- Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
- Malpighia Glabra (Acerola) Fruit Extract plant extract
- Acerola cherry extract, from the species also written Malpighia emarginata. The fruit is unusually high in vitamin C, and the extract is used as an antioxidant botanical.
- 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.
- Brassica Oleracea Italica (Broccoli) Extract plant extract
- Broccoli extract, carrying sulforaphane and vitamin C. It is used as a plant antioxidant.
- Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- 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.
- 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.
- Chamomilla Recutita (Matricaria) Flower/Leaf Extract plant extract
- German chamomile, taken from flower and leaf together. It carries bisabolol and the blue azulenes and is used for the look of reactive, reddened skin.
- 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.
- 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.
- Paeonia Suffruticosa Root Extract plant extract
- Paeonia Suffruticosa is tree peony, a long-standing East Asian medicinal plant. Its root extract carries paeoniflorin and is used for the look of reddened skin.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- Eugenol fragrance component
- Eugenol is the aromatic molecule clove oil is mostly made of, also present in basil and cinnamon. It is one of the fragrance components EU labelling requires to be named separately.
