La Roche-Posay Mela B3 Intensive Anti-Spot Serum
Hurry up, only 10 items left in stock.
Dark spots and post-acne marks don't budge with over-the-counter creams because they need a pharmacy formula that stops melanin at the source. La Roche-Posay Mela B3 combines niacinamide with gentle LHA exfoliation so your skin evens out in four weeks, not four months.
Key Benefits
- Stops melanin before it surfaces: multi-action brightening complex disrupts pigment production at its root.
- Visibly evens tone in 4 weeks: clinical studies confirm measurable spot correction with daily use.
- Gentle surface renewal: LHA exfoliates dead cells without irritation so your complexion looks smoother.
- Layers under SPF: fast-absorbing texture leaves zero greasy residue and sits comfortably beneath sunscreen.
- Hypoallergenic for reactive skin: dermatologist-tested on sensitive complexions that reject most brighteners.
- Thermal spring water base: selenium-rich La Roche-Posay water soothes while actives work.
Key Ingredients
Niacinamide (Vitamin B3): blocks melanin transfer between cells and evens your skin tone with daily application. LHA (LipoHydroxyAcid): a gentle exfoliant that lifts dead surface cells without the redness salicylic acid can cause. La Roche-Posay Thermal Spring Water: selenium-rich water from the French spa town calms reactivity and reinforces your skin's barrier while the brightening complex works.

How to Use
How to Use
Apply 3 to 4 drops to clean, dry skin every morning and evening. Smooth gently over your entire face, concentrating on dark spots or discolored patches. Follow immediately with your moisturizer. Every morning, finish with broad-spectrum SPF 50 or higher. Sun protection preserves your results and stops new spots from forming.
Frequently Asked Questions
Frequently Asked Questions
Can I use Mela B3 serum with retinol?
Yes, alternate evenings or layer Mela B3 in the morning and retinol at night. Both target different pathways, niacinamide blocks melanin transfer while retinol speeds cell turnover, so you get faster spot correction without doubling irritation.
How long until I see dark spots fade?
Clinical studies show measurable spot reduction in four weeks with twice-daily use. Consistent morning and evening application plus daily SPF 50 stops new spots while the serum corrects existing ones, so you maintain progress long-term.
Is this serum safe for melasma?
Yes, dermatologists recommend niacinamide for melasma because it blocks melanin without triggering new pigment. Apply morning and evening, always follow with broad-spectrum SPF 50, and avoid direct sun during peak hours to prevent rebound darkening.
Does Mela B3 work on post-acne marks?
Yes, niacinamide reduces the melanin transfer that causes post-inflammatory hyperpigmentation. Marks fade faster when you start treatment early, within weeks of breakout healing, and pair daily serum with SPF to block UV-triggered darkening.
