Shop dark-spot & pigmentation products →First, the honest rule
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.

Frequently asked questions
Where can I buy a genuine dark spot serum in Bangladesh?
Buy from a seller who can show the importer's invoice and batch number for that serum. TheSkinProof matches dark spot serums against the importer's invoice and batch before listing them.
Will the same tranexamic acid serum work for both oily and dry skin?
Tranexamic acid and alpha arbutin are generally well tolerated on both skin types, though dry skin may need a richer moisturizer layered on top to avoid tightness. Patch test any new serum before using it on your whole face.
How do I tell if a dark spot serum bottle might be fake?
Check that the batch code on the bottle matches the box and that the dropper seal is unbroken before you start using it. An unusual color or more irritation than expected compared to a product you have used before is also a warning sign.
