Undaria Pinnatifida Extract – Wakame Extract for Skin Care

What Is Undaria Pinnatifida Extract?

Undaria Pinnatifida Extract is an extract of the brown algae Undaria pinnatifida, also known as Wakame, Sea Mustard, or Japanese Kelp. The algae belongs to the Alariaceae family and naturally grows in marine environments exposed to factors such as UV radiation, water movement, and abrasion.

Its ability to withstand these environmental conditions is associated with its content of fucoidan, a sulphated polysaccharide that contributes to the structural integrity and stability of the algae's cell walls.

Composition and Cosmetic Properties

Undaria pinnatifida contains a range of naturally occurring compounds, including:

• Proteins
• Lipids
• Micronutrients
• Vitamins
• Sugars
• Fucoidan

Fucoidan has been reported to exhibit free-radical-scavenging and hyaluronidase-inhibiting properties. These characteristics have contributed to the use of Wakame extracts as active ingredients in cosmetic skin care formulations.

Applications in Skin Care

Undaria Pinnatifida Extract is used in cosmetic formulations where skin revitalising, conditioning, and anti-ageing properties are desired.

The original source refers to a glycerin/aqueous extract marketed as Phytessence Wakame, for which supplier research reported inhibition of hyaluronidase activity and protection against the degradation of hyaluronic acid. The reported effects included reduced deterioration of skin tissue, maintenance of dermal thickness, and improved skin firmness.

Such findings describe the properties of a specific extract and should not automatically be applied to every Undaria pinnatifida extract, as composition and activity can vary according to extraction method and raw material.
