therapeutic action: melanin production reduction

Development of dihydrooxyresveratrol-loaded nanostructured lipid carriers for safe and effective treatment of hyperpigmentation

This research developed a new skin-brightening treatment using nanoparticles to deliver oxyresveratrol and its modified form (DHO) more effectively to the skin. The scientists improved the stability of these compounds by creating tiny lipid-based carriers that protect them from light damage and help them penetrate the skin barrier. Testing showed these formulations safely reduced melanin production without harming healthy skin cells, offering promise for cosmetic products to treat dark spots and hyperpigmentation.

Synthesis and biological assessment of novel 4H-chromene-3-carbonitrile derivatives as tyrosinase inhibitors

Researchers developed new chemical compounds that can block tyrosinase, an enzyme responsible for producing excessive skin pigment that causes dark spots and discoloration. The most effective compound (6f) works better than kojic acid, a commonly used skin-lightening ingredient, and could lead to safer treatments for hyperpigmentation and related skin conditions. Computer simulations showed that one form of the compound fits better into the enzyme’s active site, making it more effective at preventing melanin production.
