RED ALGAE

RED ALGAE : Antioxidant, Hydration, Firmness

MARINE ACTIVE | CELLULAR SUPPORT & DEEP HYDRATATION

What is red algae ?

Red algae is a marine-derived active ingredient naturally rich in polysaccharides, minerals, and antioxidants. Belonging to the Rhodophyta family, it is especially valued for its benefits to the skin and connective tissues. Specific species like Chondrus crispus (Irish moss) or Lithothamnium calcareum are used in cosmetics and supplements due to their high content of carrageenans and calcium.

Used for centuries in coastal traditional medicine, red algae is now recognized as a multifunctional ingredient that deeply hydrates, strengthens the skin barrier, and combats cellular aging.

Where does red algae come from ?

Red algae is harvested in cold, shallow waters along the Atlantic and Pacific coasts, where it naturally grows on rocks. Some species are sustainably cultivated with respect for the marine ecosystem.

After harvesting, it is processed using gentle methods to preserve its active compounds: low-temperature drying, aqueous or enzymatic extraction, etc.

Properties and Active Compounds

Red algae is both hydrating and remineralizing. Its key actions include:

• Deep hydration: Its polysaccharides (carrageenans) form a protective film on the skin, reducing water loss.

• Antioxidant shield: It helps neutralize free radicals, which cause oxidative stress and cellular aging.

• Firming action: Supports collagen synthesis and improves skin elasticity.

• Mineral supply (calcium, magnesium): Vital for cellular metabolism, vascular tone, and tissue regeneration.

• Soothing effect: Calms skin inflammation and reduces redness.

What are the benefits of red algae ?

Red algae is now widely used for its combined effects on the skin, circulation, and moisture balance:

• Long-lasting skin hydration (even in harsh or dry environments).

• Improved skin elasticity and tone.

• Gentle draining effect, helpful for water retention or heavy legs.

• Reduces redness and soothes reactive skin.

• Protection from external aggressors (pollution, UV rays, climate).

How to consume or apply red algae ?

Depending on its form, red algae can be:

• Used in cosmetics (gel, serum, mask) for its hydrating and firming effects.

• Included in dietary supplements (as powder or concentrated extracts) for remineralizing or detoxifying benefits.

• Applied locally in poultices or wraps during marine spa or thalassotherapy treatments.

Any side effects ?

Red algae is generally well tolerated both topically and as a supplement. However:

• Use with caution if allergic to algae or iodine.

• High-calcium supplements should be monitored in individuals prone to kidney stones.
