Isochrysis Galbana/Phaeodactylum Tricornutum Extract

Isochrysis galbana and Phaeodactylum tricornutum are microalgae harvested from marine environments. This extract combines bioactive compounds from both species, which are then incorporated into skincare formulations as a skin conditioning agent.The extract works primarily to help maintain skin hydration and support the skin's natural protective function. It contains polysaccharides, proteins, and micronutrients derived from these nutrient-rich algal sources.

Marine microalgae extracts contain compounds that interact with the skin's outer layers to enhance moisture retention. Polysaccharides within the extract can form a light protective layer on the skin surface, helping to reduce transepidermal water loss whilst allowing the skin to breathe.The bioactive molecules may also support the skin's natural regulatory processes, contributing to a more balanced and resilient skin state over time.

This ingredient is typically found in serums, moisturisers, and hydrating masks at low to moderate concentrations. It can be used daily as part of a regular skincare routine and works well alongside other hydrating or conditioning ingredients. No special application technique is required beyond standard product use.

Generally well-tolerated across skin types. Those with shellfish or iodine sensitivities should check product labelling, as marine-derived ingredients may occasionally cause concern, though reactions are uncommon.
