Corallina Officinalis Thallus Extract

Corallina Officinalis Thallus Extract is derived from a species of red coralline algae found in marine environments. The extract contains naturally occurring polysaccharides, minerals, and trace elements characteristic of seaweed-based ingredients.In skincare formulations, it functions primarily as a skin conditioner, helping to support the skin's moisture retention and overall texture. The ingredient is typically incorporated into serums, moisturisers, and hydrating treatments.

Marine polysaccharides in coralline algae extracts are believed to form a hydrating film on the skin surface, helping to lock in moisture. This occlusive and humectant action may improve skin suppleness and reduce the appearance of rough texture.The extract's mineral profile—including calcium, magnesium, and trace elements—may also contribute to skin conditioning, though the precise mechanisms remain not fully characterised in peer-reviewed literature.

This ingredient is typically used as part of a complete hydrating routine. It works well in serums and moisturisers applied to clean skin morning and evening. For best results, apply to damp skin to enhance its moisture-binding properties, then follow with an appropriate moisturiser or facial oil if your skin type requires additional occlusion.

Generally well-tolerated across skin types. Individuals with sensitivity to marine ingredients or iodine should patch test first, as seaweed extracts can occasionally trigger sensitivity in prone individuals.
