A dermatologist Dr. Michelle Henry has revealed that the easiest way to prevent Collagen Loss as you age, with simple lifestyle habits such as wearing sunscreen daily and avoiding sun damage from UV exposure, is essential. The major structural protein in your skin, collagen, provides support, lift, firmness and resiliency. After age 30, collagen production begins to decline, contributing to common signs of aging, such as sagging skin, fine lines, wrinkles and overall crepey appearance. Wearing sunscreen with at least 30 SPF can help prevent sun damage and reduce the loss of collagen. Once a regular habit, other skin-care ingredients like peptides and antioxidants are also recommended. A balanced diet with amino acids, antioxidants and minerals is also essential for maintaining collagen.
