🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients. Hydroquinone reduces melanin synthesis by inhibiting the enzyme tyrosinase and causing reversible damage to melanocytes. Tretinoin, a retinoid, increases epidermal turnover, thinning the stratum corneum and enhancing the penetration of hydroquinone. It also helps redistribute pigment more evenly.
