Yes, excessive sugar consumption can contribute to various skin problems. High sugar intake can cause inflammation in the body, leading to increased oil production and clogged pores, which may contribute to acne breakouts. Sugar also affects collagen and elastin, proteins responsible for maintaining the skin's elasticity and firmness. When sugar molecules attach to these proteins, it can result in a process called glycation, leading to the formation of advanced glycation end-products (AGEs) that accelerate aging and contribute to wrinkles and sagging skin.
