Radiant Tone Dual Serum — Reddit Reviews
by Eucerin
Updated August 4, 2026
Contains thiamidol, which community members report visibly lightens melasma and post-inflammatory hyperpigmentation
What the community says
Dual serum with thiamidol targets stubborn hyperpigmentation and melasma, absorbs quickly with a thin lotion texture, but the strong fragrance and potential barrier irritation make it a rough ride for sensitive skin.
