Laminaria digitata Extract is a brown seaweed sourced from cold North Atlantic waters. It delivers a wealth of vitamins, minerals, phlorotannins, beta-glucans, and amino acids that support antioxidant defense, soothing, barrier reinforcement, and improved skin vitality. This blend is ideal for serums, masks, and moisturizers aimed at combating environmental stressors and premature aging.
In haircare, the formulation acts as a regenerating scalp serum and strand conditioner. The minerals and polysaccharides in Laminaria digitata aid in reinforcing hair fiber structure, enhancing moisture retention, and imparting natural shine. Simultaneously, glycerin maintains hydration, improves texture, and helps manage frizz — making it suitable for sensitive scalps and dry hair treatments.
