Dark spots can appear out of nowhere on your face and hands. And as swiftly as they pop up, they’re agonizingly slow to fade. A number of serums claim to reduce the spots and brighten skin. But do they work? And are they safe? We ask our favorite cosmetic chemist, Javon Ford, to shed some light on the situation.
Hyper-pigmentation happens when your skin makes too much melanin, and tyrosinase is the enzyme responsible for melanin production. So the way most of the brightening serums work is by impeding that process with tyrosinase inhibitors.
