Marine amino acids
Marine amino acids are a blend of amino acids derived from seaweed and other sea plants, used in skincare and haircare to help hydrate, strengthen and protect. They mimic the natural building blocks of skin and hair proteins, making them a popular choice in natural and ocean-inspired beauty products.
How it works in skincare
In cosmetics, marine amino acids function as humectants and conditioning agents that bind moisture to the skin and hair while supporting the natural protein structure. They integrate well into serums, creams and masks, where they help reinforce the skin’s barrier, improve elasticity and provide a smoother, more supple feel without heaviness.
