Undaria Peterseniana Extract

Undaria Peterseniana Extract is derived from a species of brown seaweed native to Southern Hemisphere waters. Like other marine algae, it contains polysaccharides, amino acids, and trace minerals that have traditionally been used in skincare formulations.In cosmetics, this ingredient functions as a skin conditioning agent, helping to improve the texture and feel of products while supporting the skin's moisture balance.

Seaweed extracts work primarily through their humectant properties—drawing moisture into the outer layers of the skin—and by forming a light conditioning film on the surface. The polysaccharides and amino acids in Undaria Peterseniana Extract can help bind water to the skin, whilst also providing a smoothing effect.The extract may also offer antioxidant support, though research specific to this particular species is limited.

Undaria Peterseniana Extract is typically found in hydrating serums, creams, and masks. It works well alongside other humectants such as glycerin or hyaluronic acid. As it is generally gentle, it can be used daily as part of a regular skincare routine, morning or evening.

Generally well-tolerated by most skin types. Those with iodine sensitivity or kelp allergies should patch-test products containing seaweed extracts first, as some individuals may experience mild irritation.
