Isochrysis Galbana Extract

Isochrysis galbana extract is derived from a species of microalgae found in marine environments. The extract is rich in polysaccharides, amino acids, and other bioactive compounds that function as a skin conditioning agent in skincare formulations.In products, it works primarily to improve skin texture and hydration by helping to maintain moisture levels and support the skin's natural protective functions. It is used across a range of skincare types, from serums to moisturisers.

The polysaccharides and amino acids in isochrysis galbana extract function as humectants and skin-conditioning agents. Humectants draw moisture into the outer layers of skin, whilst the amino acids support the skin's natural protein structures.The extract also contains compounds that may help reinforce the skin's barrier function, contributing to improved hydration retention and a more resilient complexion over time.

Isochrysis galbana extract is typically included in formulations at modest concentrations, so it works best as part of a broader skincare routine rather than as a standalone treatment. Use as directed on the product label, generally daily as part of your moisturiser or serum. It pairs well with other hydrating and conditioning ingredients such as glycerin or hyaluronic acid.

Isochrysis galbana extract is generally well-tolerated and suitable for most skin types. Those with known sensitivities to marine ingredients or algae-derived products should patch-test first.
