Dark spots (post-acne marks, sun spots, melasma) fade with proven, safe actives + daily sunscreen — never with mercury/steroid "fairness" creams, which are dangerous and cause rebound darkening. See the honest brightening guide.
The ingredients that actually work
Look for a serum built around one or more of these:
- Vitamin C — brightens and fades spots + antioxidant protection (AM). See best vitamin C.
- Niacinamide — fades marks, evens tone, gentle. See best niacinamide.
- Alpha arbutin / tranexamic acid — targeted spot-fading, good for melasma. See tranexamic acid.
- A retinoid (PM) — speeds turnover so spots clear faster. See retinol.
Match to your spot type
| Concern | Best pick |
|---|---|
| Post-acne dark marks | Niacinamide or vitamin C — dark-spot guide |
| Melasma (stubborn patches) | Tranexamic acid / alpha arbutin — melasma guide |
| Dullness + spots | Vitamin C |
The non-negotiable
No brightening serum works without daily SPF50+. UV re-darkens spots faster than any serum fades them. See the sunscreen guide. Give it 8–12 weeks — fading is gradual.
