Radiant Tone Dual Serum — Reddit Reviews
by Eucerin
Updated October 29, 2026
Isobutylamido Thiazolyl Resorcinol fades melasma and dark spots; fragrance and breakouts persist.
What the community says
An OTC Isobutylamido Thiazolyl Resorcinol serum for stubborn melasma, sun spots, and post-inflammatory hyperpigmentation, with a thin lotion texture that absorbs quickly. It suits persistent discoloration more than acne-prone or reactive skin, since fragrance, dryness, burning, and breakouts recur.
What this means for you
What people love
- OTC pigment-fader with standout melasma results
- Thin lotion texture; absorbs without tackiness
- Nonprescription alternative people try before lasers
