Agarum Cribrosum Extract

Agarum Cribrosum Extract is derived from a species of brown seaweed (kelp) commonly found in coastal waters. Like many seaweed extracts used in skincare, it contains polysaccharides and minerals that have been used traditionally in marine-based formulations.

In skincare products, this ingredient functions as a skin conditioner, meaning it is intended to help improve the feel, appearance, and hydration status of the skin surface. It does not penetrate deeply into the dermis, but rather works on the outermost layers to support a smoother, more supple appearance.

Seaweed extracts like Agarum Cribrosum work primarily through their polysaccharide content, which can form a light film on the skin surface. This film helps to reduce transepidermal water loss (TEWL), keeping moisture in the skin and supporting hydration levels.

The ingredient may also provide trace minerals such as iodine, magnesium, and potassium, which some research suggests play a supporting role in skin health, though the extent of absorption and efficacy through topical application remains an active area of investigation.

Agarum Cribrosum Extract is typically found in serums, creams, masks, and moisturisers. It works well in combination with other hydrating ingredients such as hyaluronic acid or glycerin. There is no need for special application technique; use as directed on the product label, typically morning and/or evening depending on the formulation.
