About This Product
Cysteamine is a naturally occurring amino acid derivative that outperforms hydroquinone in clinical studies — without the side effects. It works by reducing existing melanin deposits while slowing the production of new pigment. If you've tried vitamin C, kojic acid, and niacinamide and your melasma is still there, cysteamine is likely the next move. This is the serious option for resistant pigmentation.
Key Benefits
- Cysteamine clinically proven to outperform hydroquinone
