How it works
Tocopheryl Acetate is named on the ingredient panel on this cream. Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula. On this panel it sits alongside Hydrogenated Vegetable Oil, Phospholipids and Allantoin. Plant oil hardened by hydrogenation. It behaves as a soft solid, so it gives balms and sticks their body and slows water loss from the surface.

How to use
- Use the Extreme Cream as the last skincare step, morning and evening, over serum.
- Spread evenly on the face and pat gently with fingertips to aid absorption. To enhance absorption, warm up product by rubbing the desired amount in palm of hands, and then apply on skin.
- It closes the routine at night, and in the morning it is the layer sunscreen goes over.
- Twice a day. Do not skip it on an oily day; without a sealing layer the water the steps beneath it brought in leaves again.
What is the Extreme Cream?
Extreme Cream is Realbarrier's cushioned moisturizer, formulated as moisturizing step in a Korean skincare routine. It suits sensitive, dry, normal skin types, and it is sourced here as the authentic Korean-market formula rather than a US-shelf reformulation.
How should I use the Extreme Cream?
Warm a small amount between the palms and press evenly over the face and neck as the last step of a morning or evening routine. Working it in this order keeps the cushioned texture behaving the way Realbarrier formulated it to, rather than rushing straight to the next step in the routine.
How often should I use this moisturizer?
Morning and evening as the last step of a routine, adjusting the amount for how dry or oily skin feels that day. Consistency across a full skin cycle of several weeks matters far more than an occasional use for a moisturizer like this one, since most of its benefit shows up with steady, repeated application.
Who is this moisturizer best suited for?
This moisturizer is best suited for sensitive, dry, normal, combination skin, particularly anyone dealing with rough, flaky or wind-chapped texture. Patch test on the inner arm before a first full-face application if skin tends to react easily.
What are the key ingredients in this moisturizer?
The formula lists Panthenol, Olea Europaea Fruit Oil and Allantoin among its ingredients, alongside the rest of the base that carries them across the skin. Each one is named here in the exact form it appears on Realbarrier's own ingredient list, not inferred from the product name.

40 of 47 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.
- 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.
- 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.
- 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.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- 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.
- 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.
- 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.
- 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.
- Sorbitan Stearate emulsifier
- Sorbitan Stearate is a mild emulsifier and thickener used to hold oil and water together in creams.
- 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.
- Limnanthes Alba Seed Oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
28 more explained
- Olea Europaea 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.
- Hydrogenated Vegetable Oil occlusive
- Plant oil hardened by hydrogenation. It behaves as a soft solid, so it gives balms and sticks their body and slows water loss from the surface.
- Xylitylglucoside humectant
- Xylitylglucoside is a sugar-derived humectant, the third member of the xylitol blend. Together the three hold water in the outer layer for longer than any of them does alone.
- Anhydroxylitol humectant
- Anhydroxylitol is a xylitol derivative used as a humectant. It is almost always part of the xylitol, anhydroxylitol and xylitylglucoside blend sold as a moisture-retention complex.
- Xylitol humectant
- Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
- 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.
- Tocopheryl Acetate antioxidant
- Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
- Phytosterols emollient
- Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
- Phospholipids barrier lipid
- Phospholipids are the lipid class lecithin belongs to, with a water friendly head and two fatty tails. That shape is what lets them form liposomes and hold an emulsion together.
- 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.
- Acetyl Heptapeptide-4 peptide
- A seven-amino-acid peptide with an acetyl group added for stability. It is used as a conditioning peptide for the look of firmness.
- Helianthus Annuus 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.
- Salvia Officinalis Oil fragrance component
- Sage essential oil. It scents a formula and carries the plant's own aromatic compounds, which is also why it can bother reactive skin.
- Pogostemon Cablin Oil fragrance component
- Patchouli oil, steam distilled from the leaves. It is one of the heaviest, longest lasting aromatic oils and is used to scent a formula and to hold lighter notes in place.
- Mentha Arvensis Leaf Oil fragrance
- Cornmint oil, the main commercial source of menthol. It smells and feels close to peppermint.
- Anthemis Nobilis Flower Oil fragrance component
- Anthemis Nobilis is Roman chamomile. The flower oil is an essential oil, so it scents a formula as well as conditioning it, and essential oils are the class most likely to bother reactive skin.
- Juniperus Mexicana Oil fragrance
- Texas cedarwood oil, used for a dry woody note. It is an aromatic ingredient rather than a functional one.
- Biosaccharide Gum-1 polysaccharide
- Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Sorbitan Laurate emulsifier
- Sorbitan Laurate is a light emulsifier and solubiliser, used to keep small amounts of oil or fragrance dissolved in a watery formula.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Sodium Levulinate preservative
- The sodium salt of levulinic acid, and the other half of a plant-derived preservative pair. It is used in formulas built without traditional preservatives.
- 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.
