photo-aging
Photo-aging refers to skin damage caused by prolonged exposure to ultraviolet (UV) rays from the sun or artificial sources like tanning beds. Over time, UV radiation penetrates the skin, breaking down collagen and elastin—proteins that keep skin firm and elastic. This process leads to wrinkles, fine lines, uneven pigmentation, and a loss of skin tone. Photo-aging differs from natural aging, as it accelerates skin deterioration and can occur at any age with frequent sun exposure. Protecting skin with sunscreen, wearing protective clothing, and avoiding peak sun hours can help prevent or reduce photo-aging effects.
