10. Poor Diet High in Sugar and Processed Foods

Eating too much sugar and processed food triggers glycation, a process that damages collagen and elastin fibers in the skin. The result? Increased wrinkles, loss of firmness, and a dull complexion. A diet rich in antioxidants, fruits, and vegetables helps support healthy skin aging, while frequent junk food choices speed up visible aging. Swapping sugary snacks for nutrient-dense options can visibly improve your skin’s youthful appearance over time and boost overall skin health.
