How it works
At 200ml this is an essence sized to be poured rather than dropped, which changes how freely you use it. It is thinner than an ampoule and heavier than a toner, so it sits between the two in a routine. That is the difference from a cream, which is built mostly to hold what is already there rather than to concentrate one job into a thin layer. Its place is after the toner and before the moisturizer, on skin that is still slightly damp. What you can judge yourself is how the skin looks and feels a few minutes later, and how it behaves under the rest of the routine.
Key benefits
- Squalane sits at position #4 of 50 on Atobarrier 365 Hydro Essence's own manufacturer ingredient list.
- Lactic Acid is also named on that same list, further down the formula.
- Atobarrier 365 Hydro Essence is a essence from AESTURA, taking the essence's usual place in a layered Korean routine.
- AESTURA ships Atobarrier 365 Hydro Essence here as the Korean-market formula, the same version sold on shelves in Korea, not a US-shelf reformulation.
- Sold with intact Korean-market barcode and batch coding rather than a US-retail relabel.
Inside the formula
Inside the formula
What is this product, and who is it for?
It is a hydrating essence in a 200ml bottle, made for dry skin that wants a generous watery step rather than a few drops. A moisturizer cannot do the same thing here, because it is spread thicker and does more general work. You can judge it on how quickly it settles and how the face looks once the cream is on over it.
Where in my routine does this go?
After the watery step and before the moisturizer. The order that works is thinnest to thickest, so cleanser, then toner, then this, then cream, then sunscreen in the morning. Apply it while the face is still slightly damp. If you use more than one serum, put the thinnest one on first and give each a moment to settle.
How much should I use?
Three or four drops, or a dab about the size of a small pea, is enough for a whole face. Press it in rather than rubbing, working from the centre outward. Twice a day is normal, morning and night. Using more per application will not do more; it will mostly sit on the surface and transfer onto your collar.
Can I layer this with my other serums?
Yes, as long as you go thinnest to thickest and give each layer a few seconds. Put the most watery product on first, then this, then anything richer. Two serums doing the same job is redundant rather than harmful. If a layer feels wet, wait rather than piling the next one on top of it.

Ingredient list read from stylekorean.com on 10 September 2026.
49 of 49 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.
- 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.
- 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.
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- 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.
- 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.
- 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.
- 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.
- 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.
- Natto Gum 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.
37 more explained
- 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.
- Hydroxypropyl Bispalmitamide MEA barrier lipid
- A synthetic ceramide analogue, built to the same shape as a natural ceramide from palmitic acid. It is used as one of the lipids in a barrier style formula.
- 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.
- PCA humectant
- PCA is pyrrolidone carboxylic acid, one of the components of the natural moisturising factor skin makes for itself. It holds water at the surface, and its salts do the same job.
- Lactic Acid exfoliant
- Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry 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.
- Glycine amino acid
- Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
- 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.
- Sodium Glycerophosphate humectant
- The sodium salt of glycerin bound to phosphate. It is water soluble, holds water like other polyol salts, and also acts as a mild buffer.
- Serine amino acid
- Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
- Glutamic Acid amino acid
- Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
- 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.
- Acrylates/Ammonium Methacrylate Copolymer film former
- A synthetic copolymer used as a film former and a suspending agent. It sets to a flexible film, which is what holds a peel off or long wearing formula together.
- Potassium Magnesium Aspartate mineral
- Potassium and magnesium carried on the amino acid aspartic acid, which keeps both minerals soluble in water. It is used as a mineral source and a humectant salt.
- Aspartic Acid amino acid
- Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
- Leucine amino acid
- Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
- 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.
- Alanine amino acid
- Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
- Lysine amino acid
- Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
- 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.
- Calcium Gluconate mineral
- The calcium salt of gluconic acid, a readily water soluble way to bring calcium into a formula. It is used as a mineral source and a mild buffering salt.
- Magnesium Gluconate mineral
- The magnesium salt of gluconic acid, a readily water soluble way to bring magnesium into a formula. It is used as a mineral source and a mild buffering salt.
- Tyrosine amino acid
- Tyrosine is an amino acid used as a conditioning humectant in amino acid complexes.
- Phenylalanine amino acid
- Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
- Proline amino acid
- Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
- Threonine amino acid
- Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
- Valine amino acid
- Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
- Isoleucine amino acid
- Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Histidine amino acid
- Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
- Silica absorbent
- Silica is finely milled mineral, essentially very pure sand. It absorbs oil, stops powders clumping and soft-focuses the look of pores and fine lines.
- Acetyl Glucosamine active
- Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide.
- Creatine amino acid
- Creatine is a small amino acid derivative the body uses to carry energy in muscle. In a formula it is a water soluble conditioning ingredient.
- Uric Acid antioxidant
- Uric acid is one of the antioxidant molecules present in sweat and in the surface layer of skin. It is used at low levels as a water soluble antioxidant.
- Cysteine amino acid
- Cysteine is a sulphur-bearing amino acid used as a humectant and antioxidant. It is one of the three building blocks of glutathione.
- Methionine amino acid
- Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.

How to use
- Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
- Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
- Follow with a moisturizer within a minute so the thin layer has something holding it down.
- Do not stack it under a second serum doing the same job, since more layers is not the same as more result.
Worth knowing
- Patch test on a small area of the jaw first if your skin reacts easily to something new.
- Decant a little into the palm rather than tipping the bottle onto the face, which wastes more than it puts on.
