This is a neat idea from Olay: camouflage your age spots whilst fading them. Olay's Definity Color Recapture ($29) has a complex that several independent studies have shown can reduce hyperpigmentation: niacinamide and glucosamine.

Glucomsamine is an amino sugar that is usually harvested from shellfish. Studies show that it can reduce melanin production. However, the research also suggests that it works even better if combined with niacinamide - as it is in this tinted moisturizer from Olay.
