Description

Each drop activates a unique process to correct dark spots correction and support the skin's rebalancing.
The result: a visibly more even complexion and long-lasting protection against pigmentary recurrence¹/².

Formulated with an exclusive trio of algae extracts, including Alga-Biotic (a patented active developed by Laboratoires de Biarritz), combined with vitamin C, this serum delivers a comprehensive response to dark spots.

  • From the very first hours, radiance is restored: the skin’s appearance improves and the complexion looks brighter and more luminous¹.
  • After 14 days: dark spots are visibly reduced in size and intensity; even long-established spots appear corrected¹.
  • Over time, the appearance of new dark spots is reduced - with proven anti-recurrence action¹/²!

The Dark Spot Serum is suitable for areas prone to pigmentation, including the face, neck and décolleté, as well as other areas affected by dark spots, such as hyperpigmented dark circles under the eyes, or the hands.

Its texture and fragrance?
Its light, water-based texture absorbs quickly and leaves no greasy or sticky finish.
A sweet and delicate fragrance, of 100% natural origin, makes daily application a pleasure.

Who is it for?
Formulated for all skin types, including the most sensitive, with a non-irritating formula tested under dermatological supervision.
Suitable for all phototypes, from the lightest to the darkest. 
The formula is also suitable for pregnant and breastfeeding women.

¹ 56-day clinical study, with twice-daily application of the serum, conducted on a multi-ethnic panel of 30 subjects presenting all types of dark spots, 50% of whom have sensitive skin.

Composition

Certified Organic formula, made with 100% ingredients of natural origin and 28% Organic ingredients.

Key Ingredients:

  • Alga-Biotic (Laboratoires de Biarritz patent-pending), an algae extract combining two complementary mechanisms:
    - It modulates inflammatory signals that activate melanogenesis,
    - It strengthens the skin microbiome through a prebiotic action, helping to reduce the risk of inflammation.
    A unique dual action to effectively help prevent post-inflammatory hyperpigmentation.
  • Iridescent Algae Extract: By acting at the heart of pigment-producing cells, it blocks the pigmentation chain while breaking down existing pigments.
  • Red Algae Extract: By acting on cellular memory, it directly targets the memory of melanocytes (the cells responsible for melanin production). Its action helps modulate their reactivity to external aggressions: UV rays, blue light, inflammation, hormonal fluctuations... As a result, melanin production is better regulated and the risk of recurrence is limited. The appearance of new dark spots is limited at the source, for a preventive, long-term action.
  • Vitamin C: Helps restore radiance and brighten the complexion.

Vegan: the product contains no raw materials of animal origin and was not tested on animals (in accordance with EU legislation).
