Detailed answer

Consuming excessive amounts of sugar can have several negative effects on aging skin. When sugar is broken down in the body, it can lead to a process called glycation, where sugar molecules attach to proteins, causing them to become stiff and malformed. This can result in the formation of advanced glycation end products (AGEs), which can damage collagen and elastin fibers, leading to wrinkles, sagging, and loss of elasticity. Additionally, high sugar intake can promote inflammation, which can exacerbate skin conditions such as acne and rosacea. Finally, sugar-rich diets are often associated with weight gain and obesity, which can impact overall skin health and contribute to the development of conditions such as stretch marks and cellulite.
