The sun causes the most damage to our skin, so protecting it when you're outside is a top priority. Skin cancer, age spots, wrinkles, freckles, and skin that's rough or dry are all symptoms of too much sun.
Staying out of the sun between 10 a.m. and 4 p.m., when the sun's rays are strongest, can help protect your skin from ultraviolet rays that do the most harm to your skin. If you do go out during that time, wear clothing that covers as much skin as possible, including wide-brimmed hats and full-length shirts and pants.
When you do expose your skin to the sun, wearing a good sunscreen can protect you. Use sunscreen with a sun protection factor (SPF) of 15 or higher. If you're at the beach or exercising outside, make sure that it's water-resistant and sweat-proof, and that it'll protect you from a broad spectrum of radiation (both UVA and UVB rays). Reapply the sunscreen as needed [source: MedicineNet.com].
And while indoor tanning is popular, tanning beds harm skin cells in the same ways as the sun, increasing the risk of skin cancer later in life [source: American Skin Association].
Protecting your skin also means keeping it clean. Next, we'll look at the relationship between clean skin and smooth skin.
