| Ingredient | What it is | What it does for skin |
|---|---|---|
| Betaine Salicylate (BHA) | A gentler, betaine-bound form of salicylic acid (BHA). | Exfoliates inside pores to clear buildup and control oil, generally considered milder than standard salicylic acid.Note: An active exfoliant. Gentler than standard salicylic acid, but still worth noting for reactive, already-compromised, or exfoliant-sensitive skin, especially with daily use. |
| Tea tree oil | The essential oil pressed from Melaleuca alternifolia leaves, a concentrated form with active antimicrobial compounds like terpinen-4-ol; distinct from and more potent than the plain extract. | Has documented antibacterial and anti-inflammatory effects, commonly used for acne-prone and oily skin; as a concentrated essential oil it also carries a real irritation and sensitization risk for reactive or fragrance-sensitive skin.Note: A concentrated essential oil with real sensitization risk, especially for reactive or fragrance-sensitive skin. Worth a patch test before regular use. |
| Allantoin | A soothing compound, naturally occurring in some plants and also made synthetically. | Calms irritation and supports skin healing, often paired with other barrier-focused ingredients. |
| Evening primrose extract | An extract from the evening primrose plant, rich in fatty acids. | Commonly included as a skin-conditioning, mildly soothing ingredient. |
| Lotus leaf extract | An extract from lotus leaves, used in some Korean skincare for its antioxidant content. | Commonly included for a refreshing, mild astringent, antioxidant effect. |
