Our R&D began with a focus on one of the red seaweed species from the Basque coast, then investigating other active molecules found in the oceans. All are beneficial for keeping the skin healthy.
OUR INGREDIENTS FROM THE OCEANS
Gelidium sesquipedale is well known by lovers of the Basque Coast, a red seaweed that grows on rocky reefs battered by tides, currents, and swell. It provides us with the antioxidant and reparative properties of our patented extracts, Alga-Gorria® and Alga Sendatu®. At Laboratoires de Biarritz, we only use what nature gives us: never picked or cut from its stem, Gelidium sesquipedale is gathered when it naturally breaks off and washes ashore in the fall.
Before being incorporated into innovative formulas, our marine-origin ingredients must prove their efficacy. In this way, in vitro, in vivo, and ex vivo testing is used to confirm their targeted properties. Each ingredient has proven its usefulness in fixing skin deficiencies or protecting the skin in its own unique way.
Alga-Gorria®, Patented Antioxidant
By neutralizing free radicals, Alga-Gorria® protects cells and prevents premature skin aging.
Free radicals are very unstable fragments of molecules that can affect, through oxidization, all cellular components: DNA, structural proteins, membrane lipids, and enzymes... In the dermis, they damage the structural components that provide the youth of the skin, like collagen and elastin fibers, stocks of hyaluronic acid, and promote an acceleration of skin aging. Among the agents that cause excessive and harmful production of free radicals is UVA radiation, constant all year long.
Our patented extract Alga-Gorria® is a powerful antioxidant. It is made up of a combination of carotenoids (lutein and zeaxanthin) and mycosporine-like amino acids, which give it the power to neutralize a broad spectrum of free radicals.
Alga-Sendatu®: exclusive reparative active ingredient
Alga Sendatu® promotes the reparation of the upper layers of the skin and restores the protective barrier function of the skin.
The epidermis is the first tissue of our bodies exposed to the outside world. Its integrity must be maintained in order to fulfill the two essential roles of the "skin barrier": protection against external pathogenic agents and regulation of hydration. However, it can easily be subjected to alteration (rubbing, intrusion, irritation, inflammation, etc.) and see its capabilities reduced.
Alga Sendatu® stimulates the regeneration and maturation of keratinocytes, helping epidermal epithelial reconstruction.
In in vitro and ex vivo testing, Alga-Sendatu® has demonstrated its efficacy in promoting for epidermal and dermal regeneration:
• Fibroblast renewal
• Keratinocyte multiplication
• Keratinocyte migration and differentiation
• Increase of keratinocyte adhesion at the dermal-epidermal junction
Alga Sendatu® also reduces the reactivity of very sensitive skin.
Alga-Paisium, Exclusive Soothing Ingredient
Up to the age of 2-3, the skin of the infant is under development. Some parameters, such as permeability and sensitivity to external insult are very different from mature skin. The acid mantle is fragile and cannot completely fulfill its role as a protective shield.
More fragile, the skin dries out faster and is more sensitive to external stress. It can easily redden due to the rubbing of diapers or clothing, sudden changes in the weather, etc. Made out of the brown seaweed Fucus vesiculosus, Alga-Paisium is an exclusive extract rich in phlorotannins. Its phlorotannins have been proven beneficial in maintaining skin integrity, notably thanks to intrinsic anti-inflammatory and anti-allergic properties.
In vitro testing demonstrated the efficacy of the Alga-Paisium extract for reducing markers of skin inflammation.
Alaria esculenta: Tonifying Ingredient
Alaria esculenta is a long and thin brown seaweed with tonifying properties.
Ex vivo testing demonstrated its anticollagenase and antielastase activity (preserving collagen and elastin fibrils).
Skin suppleness and elasticity is preserved.
Rock Samphire: Revitalizing Ingredient
Extracted from a highly resistant seaside plant, the Rock Samphire extract revitalizes the skin through the stimulation of energy production in cells.
An ex vivo test (dosing CO2 release after the metabolisation of glucose-6-phosphate) demonstrated the activation of cellular respiration by the Rock Samphire extract.
Cellular respiration leads to energy production, under the form of ATP.
