Collagen is one of the major building blocks of bones, muscles, tendons, and ligaments. It minimizes fine lines and wrinkles, reduces sun damage, improves skin elasticity, corrects weak or damaged nail beds, thickens fine hair, and slows hair loss. This product contains 12,500 mg of Marine Collagen Type 1 and 3 per serving. It also includes vitamins B5, B6, B7 (biotin), B12, and C, as well as selenium and hyaluronic acid, which help to moisturize, soothe, heal, and regenerate the skin, and protect it from UV rays. These nutrients work together to improve skin tone and texture, hydration, and reduce signs of aging.
