Product Overview
4-Butylresorcinol is a highly effective skin-brightening and depigmenting agent widely used in advanced cosmetic formulations targeting hyperpigmentation, dark spots, and uneven skin tone. It works by inhibiting tyrosinase activity, a key enzyme involved in melanin synthesis, thereby helping reduce excess melanin production.
Compared to traditional brightening agents, 4-Butylresorcinol offers strong efficacy at low usage levels, making it suitable for high-performance skincare products with a premium positioning. It is commonly used in serums, creams, and spot-treatment formulations designed for intensive brightening and tone correction.
4-Butylresorcinol is especially valued in modern cosmetic formulations where visible brightening results, formulation stability, and skin tolerance are required.
