Murad Rapid Dark Spot Correcting Serum is a physician-developed, Environmental Shield™ brightening serum specifically formulated to address stubborn dark spots — including post-inflammatory hyperpigmentation (PIH), UV-triggered brown spots, and environmental pollution-induced discoloration — through a multi-mechanism approach that targets melanin production, transfers, and existing pigmentation simultaneously. 1 fl oz.

Tranexamic Acid is the primary brightening active — inhibiting the plasminogen-plasmin pathway that drives melanocyte-keratinocyte crosstalk after UV, inflammation, and pollution exposure, addressing the upstream trigger of melanin overproduction. Kojic Acid (from fungal fermentation) directly inhibits tyrosinase — the enzyme responsible for melanin synthesis. Niacinamide (Vitamin B3) blocks melanin transfer from melanocytes to keratinocytes — disrupting the distribution pathway downstream of synthesis. OAT EXTRACT and Vitamin C derivatives provide antioxidant protection against pollution-induced free radical pigmentation triggers. The Environmental Shield™ complex provides anti-pollution protection that prevents new dark spot formation from environmental stressors. Clinical study: visible improvement in dark spot intensity in 1 week. Murad is a clinical skincare brand founded by dermatologist Dr. Howard Murad, M.D. — one of the first dermatologists to pioneer the use of exfoliating acids in skincare and formulate dermatologist-grade clinical treatments for retail. All products are cruelty-free and made in the USA. Available at Beauty Riche with same-day shipping.
