Co-developed with leading dermatologists and pigmentation experts, MELA B3 combines new multi-patented Melasyl™ ingredient - our active melanin trapper - with 10% Niacinamide (also known as Vitamin B3) for a multi-action against hyperpigmentation that also soothes skin & strengthens the skin barrier. Acts to lighten the appearance of existing pigmentation whilst helping prevent the appearance of future dark spot discolouration. Helps even skin’s tone with an ultra-sensorial lightweight gel-serum texture. 

Clinically tested on dark spot prone skin. Dark Spots Clinically Reduced for 94%*

Hyperpigmentation Innovation: new multi-patented Melasyl™ active. Fight Hyperpigmentation. A new mode of action, like never before. Intercepts excess melanin at a different stage of its production before it marks the skin.

*50 subjects, instrumental measurement of size of overall area of dark spots after 12 weeks. 

THE SCIENCE BEHIND

Melanin production: Melasyl™ has a new mode of action compared with referent dermatological actives: it’s an interceptor of melanin precursors. It acts early in the mechanism of melanin synthesis to avoid its overproduction and the appearance of pigmentary concerns in the form of dark spots on the skin.  Clinically tested on all skin tones, our multi-patented Melasyl™ is the result of 18 years of research, selected over 4,000 molecules. Honouring the skin’s natural melanin production, MELA B3 respects the natural beauty of our skin, suitable for all tones and types, including sensitive skin. Alcohol-free, hypoallergenic & non-comedogenic formula, developed with dermatologists. Targets all pigment irregularities even persistent dark spots. Also suitable for those who may be prone to post-acne marks (post-inflammatory hyperpigmentation/ PIH), sun spots and age spots.  Complete formula acts in several ways to reduce the appearance of hyperpigmentation. Active ingredients include: Melasyl™, 10% Niacinamide, Retinol (retinyl palmitate), Hyaluronic Acid & LHA. Our formula gently promotes skin surface renewal & exfoliation for a more radiant look.

Rated 5 out of 5 by from Love this product due to I ultra sensitive skin LeRoche-Posay Correct and Protect collection with Mela B3

Rated 1 out of 5 by from Not Suitable for Sensitive Skin as Claimed I purchased this serum hoping to treat some mild hyperpigmentation, especially since it's marketed as suitable for sensitive skin. Unfortunately, after just a week of daily use (day and night), my skin began reacting quite badly. I developed a noticeable burning sensation whenever I applied the serum, followed by red patches and irritation on my cheeks. It got to the point where even my regular moisturizer stung upon application. I have sensitive skin, and I was cautious not to pair it with any other active ingredients. Still, this product did not work for me and actually worsened my skin barrier. I’ve since had to stop using it entirely and switch to calming, barrier-repair products. I’m really disappointed, especially given the claims that it’s suitable for sensitive skin types. I would recommend doing a patch test or speaking to a dermatologist before trying this if your skin is reactive at all.

Rated 5 out of 5 by from Amazing serum Nice product. Noticed my skin became brighter after just 7 days of use. Will definitely buy again. As with all skincare, it needs consistency. The active ingredients really does what it says

Rated 5 out of 5 by from best for acne marks Product was very effective. It treated hyperpigmentation and acne marks. I saw the results instantly. I have tried other products but so far this is the best.
Date published: 2025-04-05
Rated 2 out of 5 by from Not very effective on my brown skin. I have been using this for 8 weeks and unfortunately this is not working for me. The texture of my face is nice but the discolouration remains much the same. I think I have persevered long enough. I am disappointed.

Rated 1 out of 5 by from For something this pricey… You’d think you’d be getting the holy grail of dark spot removal But you’ll only end with with more acne for acne prone skins and just a dryer skin For such an investment I promise I hoped I would be one of the few leaving a good review
