How it works
Mediheal built its reputation in Korea on dermatology-clinic-style sheet masks sold by the box, and has since carried that same single-use format into pads, ampoules and creams, and The Teatree Calming Powder Wash 50g is one of its makeup base entries. Betaine sits within the first ten ingredients, a humectant and comfort ingredient common across Korean bases. Tea Tree Leaf Oil sits within the first ten ingredients, the ingredient behind Mediheal's tea-tree line and a long-standing Korean choice for oil-prone, blemish-prone skin. Tea Tree Leaf Oil sits further down the ingredient list, the ingredient behind Mediheal's tea-tree line and a long-standing Korean choice for oil-prone, blemish-prone skin. Tea Tree Leaf Oil sits further down the ingredient list, the ingredient behind Mediheal's tea-tree line and a long-standing Korean choice for oil-prone, blemish-prone skin. As a makeup base, it functions as a complexion-prep step used before or in place of foundation in a layered Korean routine. It comes in a 50g format.

Ingredient list read from mediheal.com on 10 September 2026.
32 of 32 explained
- Zea Mays (Corn) Starch absorbent
- Corn Starch absorbs oil and moisture and gives a soft, matte finish. It also thickens a formula.
- Sodium Cocoyl Glycinate surfactant
- An amino-acid surfactant built from coconut fatty acids and glycine. Amino-acid surfactants clean at a pH close to the pH of skin itself, which is why low-pH Korean cleansers are built on them.
- Potassium Myristate surfactant
- Potassium Myristate is the soap made from myristic acid. It gives a cleanser a dense, creamy lather, and being a soap it works at alkaline pH.
- Pullulan film former
- Pullulan is a fermentation-derived polysaccharide that dries to a tight film, which is why it produces a temporary, visible tightening feel on the skin.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the 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.
- Melaleuca Alternifolia (Tea Tree) Leaf Oil fragrance component
- Tea Tree Leaf Oil is an essential oil from an Australian shrub, carrying terpinen-4-ol. Korean formulas use it in products aimed at blemish-prone skin; it is potent, aromatic, and one of the essential oils most likely to bother reactive skin.
- Chromium Oxide Greens colorant
- Chromium Oxide Greens is a dull green mineral pigment. It is inert, sits on the surface, and is used in small amounts to correct the look of redness in a tinted product.
- 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.
- Papain exfoliant
- Papain is a protein-cutting enzyme from papaya. Enzyme exfoliants act on protein rather than on the bonds an acid targets, and they need water to work, which is why they suit powder washes.
- 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.
- Bromelain active
- Bromelain is the protein splitting enzyme group found in pineapple stem and fruit. In cosmetics it is used in enzyme formulas that loosen the keratin holding dead surface cells together.
20 more explained
- 4-Terpineol fragrance component
- A terpene alcohol, and the main constituent of tea tree oil. On a label it is an aromatic plant constituent rather than a functional ingredient.
- 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.
- Lactobacillus Ferment ferment
- Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
- Melaleuca Alternifolia (Tea Tree) Leaf Water plant extract
- Tea Tree Leaf Water is the distillate, used in place of plain water as a base. It carries a trace of the plant's aroma and none of the essential oil's strength.
- 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.
- 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.
- Melaleuca Alternifolia (Tea Tree) Extract plant extract
- Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.
- 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.
- 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.
- Aspartic Acid amino acid
- Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
- 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.
- Histidine amino acid
- Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Magnesium Chloride mineral
- Magnesium Chloride is the magnesium salt that makes sea water taste bitter. In a formula it is a mineral salt in the water phase and helps set gum gels.
- Calcium Chloride mineral
- Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.

What skin-care professionals say about skin care, quoted from the medical sources linked beside each.
Pretty much every step of a Korean skin care routine is going to have some component of hydration.
Alok Vij, MDDermatologist, Cleveland Clinic I think it's fair to say I've seen lots of patients use tea tree oil for a variety of skin issues. It's a natural remedy that is known to help.
