Gelidium Cartilagineum Extract

Gelidium cartilagineum extract is derived from a species of red algae (seaweed) commonly found in coastal waters. The extract contains polysaccharides and other marine compounds that have been used in skincare formulations for their skin-conditioning and protective properties.This ingredient functions primarily as a skin protectant, helping to maintain the integrity of the skin barrier and support the skin's natural defence mechanisms.

The polysaccharides in Gelidium cartilagineum extract form a film-like layer on the skin's surface, which helps to reduce transepidermal water loss and protect against environmental stressors. This occluding effect is characteristic of many marine polysaccharides used in skincare.The extract may also contain natural compounds with antioxidant properties, which could help neutralise free radicals and support skin health, though the extent of this benefit in finished formulations remains unclear.

This ingredient is most effective when used as part of a complete skincare routine. It works well in lightweight hydrating products, serums, and moisturisers. There is no need to use it in isolation; it performs best when combined with other proven skincare actives suited to your skin concerns.

Generally well-tolerated across skin types. Algae-derived ingredients may occasionally trigger sensitivity in individuals with shellfish or iodine sensitivities, though this is rare.
