Hydroquinone is a topical depigmenting agent that inhibits tyrosinase, reducing melanin production. It is used to treat hyperpigmentation conditions such as melasma, post-inflammatory hyperpigmentation, and dark spots.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
