The toner that put K-beauty acid exfoliation on the map. The Some By Mi AHA BHA PHA 30 Days Miracle Toner became a global phenomenon because it works — and it works for almost everyone. In a single product, it delivers the three types of chemical exfoliation that skincare professionals typically recommend as separate steps, alongside a generous dose of the brand's soothing Truecica complex to make sure acids and calm coexist in the same bottle.

The triple-acid system: Citric Acid (AHA) gently resurfaces the skin surface, loosening the bonds between dead cells for smoother texture and a brighter complexion. Salicylic Acid (100ppm BHA) penetrates oil-soluble into pores, dissolving the sebum and debris that cause blackheads and persistent breakouts. Lactobionic Acid (100ppm PHA) — the gentlest of the three — exfoliates without irritation while simultaneously hydrating and strengthening the barrier, making it the acid of choice for sensitive skin. Niacinamide brightens, refines pores, and builds barrier resilience. Tea Tree Leaf Water (10,000ppm) provides significant antibacterial and anti-inflammatory activity throughout the formula. Papaya Fruit Extract adds additional enzymatic exfoliation, while Sacred Lotus Flower Extract and Swiftlet Nest Extract soothe, brighten, and hydrate. Sodium Hyaluronate and Allantoin ensure the skin stays comfortable throughout the exfoliation process. Formulated at a gentle pH of 5.5.

Dermatologist tested. Free from 20 artificial ingredients.
