Key actives
Melaleuca Alternifolia (Tea Tree) Leaf 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.
Melaleuca 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.
Melaleuca 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.
Lactobacillus 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.
Tremella Fuciformis Polysaccharide
Tremella Fuciformis is snow mushroom. Its polysaccharide holds even more water than hyaluronic acid for its weight, which is why it appears in hydrating Korean formulas as a plant alternative.
Glycine
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.
How to use
- Apply to cleansed skin as directed and follow with the next step of a routine.

How it works
The panel on this formula names three forms of tea tree rather than one: Melaleuca Alternifolia (Tea Tree) Leaf Extract, Melaleuca Alternifolia (Tea Tree) Leaf Oil *, Melaleuca Alternifolia (Tea Tree) Leaf Water *. 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. On this panel it sits alongside Lactobacillus Ferment, Tremella Fuciformis Polysaccharide and Glycine. 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.
Worth knowing
- Patch test on the inner arm before first full use, as with any new skincare product.
