What is it?

Laminaria digitata extract is produced by aqueous, enzymatic, or hydroglycolic extraction of the dried or fresh thallus. The fucoidan fraction is often further purified for high-potency anti-aging applications. The whole extract also delivers laminarin (a skin-repairing beta-1,3-glucan), phlorotannins (marine antioxidants), and concentrated minerals.

Skin hydration, anti-aging via fibroblast support and fucoidan, antioxidant protection, barrier repair.

Key Benefits

✦
Fucoidan
Laminaria is one of the richest sources of fucoidan — a sulfated polysaccharide with documented anti-aging (fibroblast stimulation, hyaluronidase inhibition), anti-inflammatory, and antioxidant activity.
◈
Laminarin (Beta-1,3-Glucan)
A beta-glucan unique to brown algae with wound healing, immune-modulating, and skin-repairing properties — complements fucoidan's activity for comprehensive skin support.
✧
Phlorotannins
Brown algae polyphenols with UV-protective and antioxidant activity significantly stronger than many terrestrial plant polyphenols — scavenging reactive oxygen species generated by sun exposure.
◉
Iodine and Mineral Content
Rich in bioavailable iodine (supporting thyroid-regulated skin metabolism), calcium, potassium, and trace elements that support enzymatic function in skin.
