The Science of Brightening
Cysteamine is one of the only antioxidants the body produces on its own. DermaQuest harnesses it without hydroquinone to fade discoloration at the source and restore even, radiant tone.
What is Cysteamine?
Cysteamine is a naturally occurring antioxidant produced by every cell in the body. In skincare, it's prized for its ability to help regulate melanin production at the source — targeting dark spots, sun damage, and melasma without bleaching or resurfacing the skin.
DermaQuest's MelaQuest formulas use micro-encapsulated cysteamine, engineered to release gradually as it penetrates the skin. The result is a brightening effect that's more consistent, better tolerated, and built for daily, long-term use.
