Sun Damage: What It Is, How It Affects Skin, and How to Fix It

When your skin gets too much sun damage, the harmful effect of ultraviolet radiation on skin cells that leads to premature aging, discoloration, and increased cancer risk. Also known as photoaging, it’s not just about getting a tan—it’s about how your skin pays the price years later. Every minute in the sun adds up. Even on cloudy days, up to 80% of UV rays still reach your skin. This isn’t just a summer problem. It’s a daily one.

UV radiation, invisible rays from the sun that penetrate skin and damage DNA in skin cells comes in two main types: UVA and UVB. UVA goes deep, breaking down collagen and causing wrinkles. UVB burns the surface, leading to redness and peeling. Together, they’re the top cause of skin aging, the visible signs like fine lines, dark spots, and leathery texture caused by long-term sun exposure. And it’s not just cosmetic. Repeated sun damage is the leading cause of skin cancer, abnormal cell growth triggered by DNA mutations from UV exposure. Melanoma, basal cell, and squamous cell cancers all start with sun exposure—often decades before they show up.

What does sun damage actually look like? It’s not always a sunburn. Think dark spots on your cheeks, rough patches on your hands, fine lines around your eyes that weren’t there five years ago, or a red, scaly spot that won’t go away. These aren’t just "age spots"—they’re warning signs. Your skin remembers every hour in the sun, even if you don’t.

And sunscreen alone isn’t enough. You need to combine it with hats, shade, and avoiding peak sun hours. But even if you’ve skipped protection for years, it’s not too late. The skin can repair itself—slowly—if you stop the damage. Topical retinoids, vitamin C serums, and professional treatments like chemical peels can help fade discoloration and boost collagen. But the best treatment? Prevention, starting today.
