Mela B3 Double Dose Serum: Concentrated Depigmenting Treatment Correcting Dark Spots with Melasyl and Niacinamide

La Roche-Posay Mela B3 Double Dose is an intensive day and night treatment for sunspots and signs of aging. For the first time in the brand, the formula combines the concentrated power of Melasyl™ and the firming action of Proxylane™, a dual-action combination that targets even the most stubborn dark spots while restoring density and volume to the face.

Clinical results support its power: it reduces the intensity of stubborn dark spots by 30% and provides 20% more firmness immediately after just one application. Its light, fluid texture absorbs quickly without leaving a greasy residue, making it easy to incorporate into your morning and evening routine.

Main Benefits

  • It corrects sunspots and age spots, even the most persistent ones, thanks to the multi-patented Melasyl™ technology.
  • Strengthen and densify the skin's support matrix with Proxylane™, restoring lost firmness and smoothing the signs of aging.
  • It evens out skin tone and soothes the skin thanks to niacinamide, a leading dermocosmetic active ingredient.
  • Proven double effectiveness: the same treatment works day and night on pigmentation and firmness.
  • Long-lasting results: the intensity of dark spots remains reduced weeks after the treatment is completed.

Featured Ingredients

  • Melasyl™ (2-Mercaptonicotinoyl Glycine) : a multi-patented active ingredient that intercepts excess melanin before it marks the skin; its effectiveness has been tested against ten reference molecules on the market.
  • Proxylane™ (Hydroxypropyl Tetrahydropyrantriol) : the brand's most powerful firming active ingredient, it strengthens the skin's support structure and restores volume and density.
  • Niacinamide : evens skin tone, soothes the skin and helps reduce inflammation associated with pigmentation processes.
  • LHA (Capryloyl Salicylic Acid) : a salicylic derivative that promotes skin surface renewal and refines skin texture.
  • Brown algae extract (Cystoseira Tamariscifolia Extract) : complements the anti-spot action by helping to maintain a more even tone.
  • Carnosine and adenosine : contribute to preserving skin quality and softening visible signs of aging.
  • Vitamin E (Tocopherol) : an antioxidant that protects the skin against daily oxidative damage.
