Tea Tree

What it is
Tea tree, from Melaleuca alternifolia, appears in Korean skincare in genuinely different forms: a diluted hydrosol (tea tree leaf water), and a concentrated essential oil (tea tree leaf oil), with real differences in strength between the two.
What the evidence says
Tea tree is used for its antibacterial and oil-controlling properties, commonly reached for in oily and acne-prone skin formulas. The form matters: COSRX's Low pH Good Morning Gel Cleanser uses tea tree leaf water, a diluted hydrosol, gentler than concentrated tea tree oil. Manyo's Pure Cleansing Oil, by contrast, contains real tea tree leaf oil, a genuine essential oil at full concentration, a meaningfully stronger form of the same plant.
Who it's for
Oily, combination, or acne-prone skin, though the specific form (water versus oil) should match your sensitivity level.
Worth knowing
Fragrance-sensitive or reactive skin should be cautious with concentrated tea tree oil specifically, the diluted hydrosol form is the gentler option if tea tree causes irritation.
