Sugar's ability to induce wrinkles and drooping skin. These AGEs cause our skin's collagen and elastin proteins to lose elasticity and weaken. As a result, your skin begins to sag and look wrinkly. Glycation has been shown to cause wrinkles in animal models of aging, and studies have also indicated that people with higher blood sugar levels tend to have more wrinkled skin. This suggests that controlling blood sugar may help prevent wrinkles from forming as you age. Glycation is the process by which sugars react with proteins, fats, and DNA, causing them to harden and turn brown. It happens when your body reacts to high blood sugar levels by producing and storing excess amounts of glycogen (a type of storage carbohydrate) in the liver and muscles. As these tissues age, they are more likely to become stained by lipofuscin (ageing pigment found in cells such as macrophages) and to show evidence of fibrosis (the formation of excessive amounts of scar tissue). As you can see, glycation causes wrinkles by making older tissues harder and weaker. This can happen with skin, muscle, and bone tissue, so reducing your exposure to sugars will help keep glycation products away from these areas and protect them from becoming hardened and frail with age.
