A NEW anti-hyperpigmentation serum that corrects the appearance of dark spots, even persistent ones. 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 Game changer Wow, this is truly amazing! My dermatologist recommended I try this as I had a lot of dark spot pigmentation marks on my face. I have only used this alongside with the Mela B cleanser for dark spots and Anthelios invisible fluid SP 50+ sun cream for 1 week and can already see and feel a massive difference to my skin. It is expensive but you certainly get what you pay for. You've got a lifelong customer with this product.....thank you.

Rated 5 out of 5 by from Works on acne scars I had a sample of this and wasn’t really sure how to use it because the sample didn’t come with any usage instructions so I thought I’d give it a try on my stubborn dark acne scars that I’d been struggling with along my jawline and neck. I’ve only been using it for a few days and my skin is already looking clearer.

Rated 1 out of 5 by from Didn’t live up to it’s claims! I purchased this after researching best serums for dark spots and as I’ve used a La Roche-Posay SPF for years I thought I’d put my trust in them. I’ve used the serum along with the Mela B3 cleanser twice a day for just over two months. Sadly, it just didn’t live up to its claims that ‘At 4 weeks even persistent dark spots look reduced’ as I have seen no change at all. Obviously, I wasn’t expecting my dark spots to vanish but would have expected some noticeable change considering the price tag of these two products.

Rated 5 out of 5 by from Nice and stable product My skin is mixed type. I apply this product before B5 cream at night and my skin is very smooth and soft the next day. Have used it for 1 month and the condition of my skin is very stable.

Rated 1 out of 5 by from not working I am a loyal customer of this brand and mostly using a wide range of La roche products. I've used this product for nearly 3 months but it didn't work at all. Waste of money

Rated 5 out of 5 by from Lightened sun damaged patches on my face Fourth product I’ve tried for reducing sun damage on my face and this is the first one that has worked for me. Visible improvement in two to four weeks and still using. In case it’s helpful my skin is white, slightly sallow and I have some freckles.
