How it works
The Blue Oasis Aloe Hydrating Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Allantoin, named nineteenth on its own ingredient list. The same list carries Tocopherol, Hydrolyzed Vegetable Protein and Biosaccharide Gum-1, 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 serum format rather than by the list alone. This is the Original Korean Formula, the serum By Wishtrend sells in Korea, Allantoin and all.
Key benefits
- Allantoin, the active this serum is built around
- Tocopherol on the same list, an antioxidant
- Hydrolyzed Vegetable Protein on the same list, a protein
- Biosaccharide Gum-1 on the same list, a polysaccharide
- Houttuynia Cordata Extract and Malachite Extract further down the same list
- Polyglycerin-3 and Glycosyl Trehalose further down the same list
How to use
- Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM.
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 Allantoin and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Allantoin 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 Allantoin?
Tocopherol, Hydrolyzed Vegetable Protein and Biosaccharide Gum-1. The order they are printed in on this serum's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Linum Usitatissimum (Linseed) Seed Extract, Houttuynia Cordata Extract and Malachite Extract.

28 of 29 explained
- 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.
- 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.
- 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.
- 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.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- Ammonium Acryloyldimethyltaurate/VP Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
- Polyglycerin-3 humectant
- Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay blended.
- 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.
- Malachite Extract mineral
- Malachite is a green copper carbonate mineral. Its extract is used in a formula as a source of trace copper.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
- Glycosyl Trehalose humectant
- A sugar humectant built on trehalose, the sugar that lets some plants survive drying out. It holds water at the surface with a light, non-sticky feel.
16 more explained
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- Glyceryl Acrylate/Acrylic Acid Copolymer film former
- This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
- Hydrogenated Starch Hydrolysate humectant
- A starch-derived sugar syrup used as a humectant. It holds water and adds a soft cushioned slip without the tack of glycerin.
- 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.
- 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.
- 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.
- 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.
- Hydrolyzed Vegetable Protein protein
- Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface.
- Linum Usitatissimum (Linseed) Seed Extract plant extract
- Flaxseed extract. Flaxseed swells into a mucilage in water, so the extract hydrates and leaves a cushioned, slippery feel.
- Maltodextrin film former
- Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
- 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.
- 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.
- 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.
- Houttuynia Cordata Extract plant extract
- Houttuynia Cordata is heartleaf, and it is one of the two or three anchor plants of Korean calming skincare. Its extract carries quercitrin and other flavonoids and is used for the look of redness and blemish-prone skin.
- 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.
- 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.

Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Allantoin on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Allantoin rather than to three changes at once.
