Sun damage, also known as photoaging, refers to skin changes caused by prolonged exposure to ultraviolet (UV) rays. It affects the deeper layers of the skin, accelerating the breakdown of collagen and elastin. This can lead to wrinkles, sunspots, rough texture, and uneven pigmentation. Unlike natural aging, sun damage accumulates over time, often becoming more visible later in life. With the right treatments, sun-damaged skin can be repaired, revealing a smoother, healthier appearance.
