Do you want to reduce the appearance of dark spots and hyperpigmentation? Mela B3 Intense Anti-dark spot serum is our 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 and strengthens the skin barrier.

THE SCIENCE BEHIND

Looking for a cream that helps hyperpigmentation? 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. It has an alcohol-free, hypoallergenic & non-comedogenic formula, developed with dermatologists.   Melasyl™ targets all pigment irregularities even persistent dark spots. It is also suitable for those who may be prone to post-acne marks (post-inflammatory hyperpigmentation/ PIH), sun spots and age spots.  The 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 Best thing I have tried for dark spots Really happy with this product. It absorbs nicely with no greasy residue. Has a slight scent to it which is pleasant. I have been using this along side their 50+ anti dark spot fluid. Normally in the sun my dark spots become more prominent. But I’ve noticed that they haven’t when I have been using these products. I’ve also noticed a slight reduction and lightness in the dark spots I already have. Definitely gonna keep using this product and hopefully they will fade away completely.
