Betaine Salicylate (INCI: Betaine Salicylate) is a plant-derived beta hydroxy acid that blends oil-soluble exfoliation with the softening comfort of betaine. It gently helps lift away buildup and dull surface cells to reveal a smoother, more refined look—without the harsh feel often linked to stronger acids. Ideal for sensitive, combination, and congestion‑prone skin or anyone seeking a kinder, K‑beauty take on daily exfoliation.
