Dark spots, hyperpigmentation, and dullness are some of the most stubborn skin concerns. 

And while luxury skincare often focuses on indulgence, La Roche-Posay’s new Mela B3 Serum blends dermatological science with cutting-edge innovation, offering results that rival prestige brands at a fraction of the price.

This isn’t just another niacinamide serum. It’s a formula that redefines what’s possible in clinical-grade brightening. 🌿✨

What Makes Mela B3 Different?

The Mela B3 serum was developed after 18 years of research by La Roche-Posay Laboratories to target dark spots at the source.

By addressing melanin overproduction and skin inflammation, the two key causes of hyperpigmentation.

Its innovation lies in the Melasyl™ molecule, a patent-pending active that works on a completely new biological pathway compared to traditional ingredients like hydroquinone or vitamin C.

🧬 Melasyl™ intercepts the formation of melanin precursors before they become visible dark spots. 

Combined with 10% pure niacinamide (vitamin B3), it helps reduce existing pigmentation while preventing new ones from forming, without irritation or rebound effects.

The Science Behind the Formula

💠Melasyl™ (proprietary molecule): Regulates the melanogenesis cascade to reduce future dark spots.

💠10% Niacinamide (Vitamin B3): Brightens, strengthens the skin barrier, and minimizes inflammation.

💠Thermal Spring Water: Naturally rich in selenium, it soothes and reduces oxidative stress.

💠Gentle, fragrance-free formula: Suitable even for sensitive and post-procedure skin.

Clinical results from in-house trials show visible reduction in dark spots after just 2 weeks, with continued improvement up to 12 weeks.

Texture and Experience

The texture is lightweight, silky, and fast-absorbing, ideal for both day and night use. 

Unlike many pigment-correcting serums, it leaves no sticky residue and layers beautifully under sunscreen or moisturizer.

💡 Tip: Apply 3–4 drops every morning on clean skin, followed by broad-spectrum SPF 50.
