This protein is rich in amino acids, especially glutamic acid, which is essential for the synthesis of collagen and elastin in the skin. In addition, pea protein is known for its ability to increase the production of hyaluronic acid in the skin, which helps maintain skin hydration and smoothness. Pea protein is also rich in antioxidants, which help protect the skin against free radical damage and premature ageing.
