Collagen is made up of amino acids, oxygen, carbon, and hydrogen. These develop in the connective tissues and ensure the renewal of skin cells. High levels of collagen are found in all areas of your body—in the skin, muscles, ligaments, and tendons. When you are young, collagen makes up one-third of the proteins in your body.

After the age of 20, the production of natural collagen begins to diminish, and over time, the lower levels of this protein lead to the development of lines and wrinkles. While aging and gravity contribute to the loss of collagen, additional factors like exposure to UV rays, smoking, high sugar consumption, and certain autoimmune disorders can expedite the process.
