Humectant Skin protecting Moisturizing Antioxidant Anti-inflammatory Revitalizing Re-mineralizing Cell renewal boosting

Science

Mechanism of Action

This extract acts as a powerful humectant, leveraging its hygroscopic nature and components like laminarin and other hydrocolloids to attract and retain moisture. These elements form a protective layer on the skin, bolstering the natural moisturizing factor (NMF) and establishing a water reservoir within the epidermal layers, thereby significantly improving hydration and minimizing transepidermal water loss (TEWL). Additionally, its rich composition of phenolic acids (e.g., salicylic acid) and phlorotannins endows it with notable anti-inflammatory and antioxidant properties, while also stimulating blood circulation and promoting cellular renewal.
