How to Fade Pigmentation — The Evidence-Based Routine
Most pigmentation treatments don't work because they target the wrong layer. The protocol below is what dermatologists actually prescribe.
If you only read one paragraph.
Daily SPF 50, vitamin C every morning, niacinamide twice daily, 0.05% retinol nightly, gentle exfoliation 2× weekly. 16-week timeline. No shortcuts.
The full method.
- SPF 50 every morning, no exceptions. The single highest-impact step. Without daily SPF, every other treatment is fighting an uphill battle. Reapply every 3 hours when outside.
- Vitamin C in the morning. L-ascorbic acid 10-20% before moisturiser. C E Ferulic is the clinical reference. Drop to gentler forms (THD ascorbate) if irritated.
- Niacinamide twice daily. 5-10% niacinamide reduces melanin transfer. Slowest of the actives — meaningful at 12-16 weeks.
- Retinol nightly (build slowly). 0.025%-0.1%. Increases cell turnover, which sloughs pigmented cells faster.
- Tranexamic acid for melasma. If pigmentation is hormonal (melasma), add 3% tranexamic acid. The Ordinary makes the cheapest option.
- Chemical exfoliant 2× weekly. Mandelic acid (gentler) or glycolic acid (stronger). Don't combine with retinol on the same night.
- In-clinic procedures for stubborn pigmentation. Cosmelan or Pico laser if topicals plateau at 16 weeks. See a dermatologist.
What to avoid.
- Not wearing daily SPF (the entire pigmentation strategy fails without this).
- Aggressive scrubbing (creates more pigmentation through inflammation).
- Hydroquinone without medical supervision (can cause permanent darkening).
- Switching products every 2 weeks (pigmentation needs 12+ weeks to respond).
- Skipping vitamin C because it 'doesn't do much immediately'.
Common questions.
How long until pigmentation actually fades?
16-24 weeks for visible improvement on most surface pigmentation. 6-12 months for melasma. Hormonal pigmentation may rebound with sun, hormones, or pregnancy.
Will pigmentation come back?
Sun exposure recreates it. Hormonal triggers recreate melasma. Daily SPF is lifelong, not optional.
Should I see a dermatologist?
If topicals don't show improvement at 16 weeks, yes. In-clinic options (Cosmelan, lasers) may be necessary for resistant pigmentation.
Hydroquinone — is it safe?
Effective but should only be used under doctor supervision. Used incorrectly can cause ochronosis (permanent darkening). Most clients can avoid it with the protocol above.
