How it works
The panel on this cleanser names three forms of tea tree rather than one: Melaleuca Alternifolia (Tea Tree) Leaf Oil, Melaleuca Alternifolia (Tea Tree) Extract, Melaleuca Alternifolia (Tea Tree) Leaf Water. 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. On this panel it sits alongside Myristic Acid, Lauric Acid and Beeswax. Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
Key benefits
- Three forms of tea tree on one panel, not a single token inclusion
- Myristic Acid on the same panel, the formula's fatty acid
- Lauric Acid on the same panel, the formula's fatty acid
- 120 ml to a unit
- Korean-market formula, with its Korean barcode and batch code intact on the box
Key actives
3Myristic Acid
Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
5Lauric Acid
Lauric Acid is the coconut fatty acid that gives soap-style cleansers their dense foam. It is not well suited to blemish-prone skin at high levels.
11Beeswax
Beeswax is the wax bees build comb from. In a formula it thickens the oil phase and forms a breathable, water-resisting film, which is what makes a balm hold its shape.
15Melaleuca Alternifolia (Tea Tree) Leaf Oil
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.
21Melaleuca Alternifolia (Tea Tree) 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.
All products with Melaleuca Alternifolia (Tea Tree) Leaf Extract
24Melaleuca Alternifolia (Tea Tree) Leaf Water
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.

What does Melaleuca Alternifolia (Tea Tree) Leaf Oil do in this skincare formula?
Tea Tree Leaf Oil sits in the middle of the ingredient list, the ingredient behind Mediheal's tea-tree line and a long-standing Korean choice for oil-prone, blemish-prone skin.
Is Artemisia Vulgaris Oil also in this formula?
Artemisia Vulgaris Oil, the mugwort behind I'm From's signature line, sits further down the ingredient list, valued in Korean formulas for its calming role. It sits alongside Melaleuca Alternifolia (Tea Tree) Leaf Oil on MEDIHEAL's ingredient list for this product.

33 of 33 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.
- Myristic Acid fatty acid
- Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
- 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.
- Lauric Acid fatty acid
- Lauric Acid is the coconut fatty acid that gives soap-style cleansers their dense foam. It is not well suited to blemish-prone skin at high levels.
- Potassium Hydroxide pH adjuster
- Potassium Hydroxide is a strong base used in traces to raise a formula to its target pH. In a soap-style cleanser it also converts fatty acids into the surfactant that does the cleansing.
- 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.
- Glycol Distearate emollient
- A wax-like ester that thickens a cleanser and gives it a pearly opacity. It also leaves a conditioned feel behind after rinsing.
- Glyceryl Stearate SE emulsifier
- Glyceryl Stearate SE is the self-emulsifying grade, supplied with a little soap already built in so it can hold an emulsion with less help. It thickens and softens like the plain form.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- Beeswax occlusive
- Beeswax is the wax bees build comb from. In a formula it thickens the oil phase and forms a breathable, water-resisting film, which is what makes a balm hold its shape.
- Potassium Cocoyl Glycinate surfactant
- Potassium Cocoyl Glycinate is a coconut-and-glycine surfactant used in low-pH cleansers. It foams well and rinses without the squeaky tightness a soap leaves.
21 more explained
- 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.
- Coco-Betaine surfactant
- Coco-Betaine is a coconut-derived secondary surfactant used to build foam and make a cleanser milder.
- 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.
- 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.
- Artemisia Vulgaris Oil fragrance component
- Mugwort essential oil. It scents a formula as well as conditioning it, and essential oils are the class most likely to bother reactive 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.
- Lavandula Angustifolia (Lavender) Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- 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.
- 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.
- Capryloyl Salicylic Acid exfoliant
- Capryloyl Salicylic Acid is salicylic acid with a fatty tail, sometimes sold as LHA. It stays nearer the surface than salicylic acid and works at a higher pH, so it exfoliates more evenly and more gently.
- 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.
- 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.
- 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.
- 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.
- Kaolin absorbent
- Kaolin is white clay, the mildest of the cosmetic clays. It absorbs oil and lifts loose debris from the surface without stripping, which is why it is the clay used on drier skin.
- 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.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- 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.
- 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.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
