As our age gets advanced, the production of collagen slows down. And the already existing collagen can get affected because of the exposure to sun.
A study published in the American Journal of Nutrition found women over 40 with the highest amount of vitamin C in their diet were less likely to develop wrinkles than those who consumed lower levels."Vitamin C is crucial to the formation of collagen.

"Smoking creates enzymes called matrix metalloproteinases (MMPs), which damage the collagen in your skin, hence the telltale sagging which many smokers are betrayed by," says consultant dermatologist Dr Nick Lowe.
