Does Sunscreen Really Prevent Tanning? Here’s What Experts Say
Your parents weren’t wrong when acting as the sunblock police when you were younger. Although the sun on your skin can feel absolutely amazing, it’s also pretty dangerous, and can cause long-lasting negative effects that can last well beyond when a sunburn or tan fades away.
For example, sun exposure can result in premature aging, wrinkles, skin discoloration by way of “sunspots” and skin cancer, which can be deadly. Wearing sunscreen can help reduce your risk of all of these issues.
When we get tan, it’s actually our body’s way of trying to protect itself from the sun.
Within the UV light, there are two different harmful types: Ultraviolet A (UVA) and Ultraviolet B (UVB).
UVA rays are the rays associated with premature aging (the A in UVA), and UVB rays are the ones associated with sunburns (the B in UVB is for burn), according to Dr. Kautilya Shaurya of Schweiger Dermatology Group in New York. Sunscreen contains UV filters that reduce the amount of UV rays reaching your skin’s surface.
