kelp extract (macrocystis pyrifera)

back to ingredient overview

Macrocystis Pyrifera Extract is an extract of a giant brown seaweed . According to research, sea kelp as a whole is thought to be useful in skin care products thanks to its high iodine, vitamin and mineral content. It is considered an anti-septic and anti-irritant that can not only heal sun-damaged skin, but can prevent wrinkles. It is also used in beauty products because of its gelatinous quality that adds shine to hair and glow to skin (Source).

Little research exists specifically on Macrocystis Pyrifera Extract, although one study published in Cosmetics and Toiletries in 2001 did find that “An extract of the Macrocystis pyrifera seaweed showed the ability to inhibit the expression of metalloproteinases in a bicellular culture study. When the extract was included in a topical formulation and applied to the skin of human volunteers, the skin showed a reduction in wrinkles, suggesting its use in formulations making an anti aging claim.”
