4-Butylresorcinol (4-n-butylresorcinol) is a highly effective, oil-soluble phenolic derivative acting as a potent inhibitor of tyrosinase and TRP-1, key enzymes in melanin production. It treats skin hyperpigmentation, such as melasma and age spots, by preventing melanin synthesis and degradation. It is primarily used in cosmetic whitening creams and serums.
More effective than arbutin or kojic acid.
Inhibits melanin synthesis at all stages.
Provides significant anti-aging benefits.
Used in whitening lotions, serums, and sunscreens to target dark spots, post-inflammatory hyperpigmentation, and freckles. Recommended concentration: ~0.1%. Often combined with niacinamide or Vitamin C for synergistic effects.
