What is Sun Damage and Lines?
How UV exposure contributes to visible lines and what prevention looks like.
UV Causes Lines
UV radiation breaks down collagen and elastin fibers, accelerating the visible signs of aging. This process, called photoaging, is the primary cause of premature lines and uneven tone. The damage accumulates over years of exposure.
Prevention
Daily SPF 30 or higher is the most effective habit. Pair it with protective clothing, shade, and avoiding peak sun hours. Prevention is far more effective than any corrective product.
