Ingredient
Unspecified brightening products
If a brightening product will not name the active, be skeptical.

What Sharon would tell you
Brightening is one of the easiest words to put on a bottle and one of the hardest claims to evaluate without the ingredient list.
Look for named actives like vitamin C, azelaic acid, tranexamic acid, niacinamide, retinoids, or appropriate acids. If the product only says glow, radiance, or brightening without a real active, keep walking.
