Sun Advanced Radiant Tone Daily Face Lotion SPF 30 Dark Spot Corrector.

"This is a lightweight daily sunscreen with built-in dark spot corrector. The active ingredient is called thiamadol, which is clinically proven with over five years of use in Europe, Asia, and South America for helping with hyperpigmentation, including concerns like melasma and acne marks. It has been studied against 2% hydroquinone, which is the gold standard dermatologists use for melasma and dark spots, but hydroquinone is hard to get, can cause irritation, and can actually be somewhat toxic to melanocytes if used for a long period of time without breaks, potentially causing ochronosis where there's paradoxical darkening of the skin. Thiamadol has been shown to be more gentle and doesn't cause skin irritation the way hydroquinone does."
