Product Introduction
Potassium 4-Methoxysalicylate (4MSK) is a high-performance cosmetic whitening & skin‑care active ingredient, a salicylic acid derivative with enhanced lipophilicity and better water solubility due to methoxy modification. It safely regulates keratin metabolism, reduces melanin deposition, fades freckles and pigmentation, and supports anti‑inflammatory, repairing and anti‑aging effects. Widely used in whitening serums, lotions, creams, and brightening products.
