Cysteamine Complex

Inhibits the activity of tyrosinase. By disrupting tyrosinase function, cysteamine reduces the production of melanin precursors, ultimately leading to a decrease in melanin synthesis. This mechanism results in the lightening of hyperpigmented areas.

Clinical studies have demonstrated the effectiveness of cysteamine in treating hyperpigmentation, including melasma and post-inflammatory hyperpigmentation, to be 1.5x stronger than hydroquinone. In a randomized controlled trial, patients with melasma who applied a topical cysteamine cream twice daily for two months experienced a significant reduction in pigmentation compared to the control group.
