peroxidase (GPx), and catalase (CAT). These enzymes play a critical role in neutralising reactive oxygen species (ROS), thereby protecting skin cells from oxidative damage and delaying the onset of photoageing .11 Moreover, laminarin‘s ability to enhance the
skin‘s antioxidant defence system is particularly noteworthy for cosmetic chemists interested in formulating products aimed at preventing or reversing UV-induced skin damage. The study by Ahn et al. demonstrated that laminarin not only reduced the thickness of the epidermis—a common sign of UV-induced skin damage—but also preserved the integrity of collagen fibres in the dermis.

This preservation of collagen is essential for
maintaining skin elasticity and firmness, making laminarin a valuable ingredient for anti-ageing skin care products .11 Further supporting laminarin‘s protective
role in skin care, research by Lee et al. (2022) explored its effects on atopic dermatitis. The study found that laminarin significantly reduced skin inflammation, epidermal and dermal thickening, mast cell infiltration, and serum IgE levels—markers typically associated with allergic and inflammatory skin conditions.12 These findings suggest that laminarin could
be effectively utilised in formulations designed for sensitive skin or for treating conditions
such as eczema. Its ability to reduce pro- inflammatory cytokine expression and enhance skin barrier function underscores its potential as a multifunctional ingredient in cosmeceuticals. Given laminarin‘s multifaceted properties, it
holds promise for integration into a wide range of skin care formulations. Its ability to modulate inflammation, boost antioxidant defences, and protect against environmental stressors makes it particularly suitable for products aimed at anti-ageing, sensitive skin care, and post-sun exposure treatments. Furthermore, laminarin‘s compatibility
with other marine-derived ingredients, such as fucoidan and hyaluronic acid, opens up
