Sun protection FAQs
The most important way to take care of your skin is to protect it from the sun. A lifetime of sun exposure can cause wrinkles, freckles, age spots and rough, dry skin. Sun exposure can also cause more-serious problems, such as skin cancer. For the most complete sun protection:
Avoid the sun between 10 a.m. and 4 p.m.
This is when the sun's rays are the strongest.
Wear protective clothing
Cover your skin with tightly woven long-sleeved shirts, long pants and wide-brimmed hats. You might also opt for special sun-protective clothing, which is specifically designed to block ultraviolet rays while keeping you cool and comfortable.
Use sunscreen when you are in the sun
Apply generous amounts of broad-spectrum sunscreen 30 minutes before going outdoors and reapply every two hours, after heavy sweating or after being in water. The best sunscreen products contain zinc oxide, titanium dioxide or both.
Sunscreen absorbs, reflects or scatters UV light. It's divided into three wavelength bands — ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC). Only UVA and UVB rays reach the earth.
Sunscreens provide either physical or chemical protection from UV light.
They form an opaque film that reflects or scatters UV light before it can penetrate the skin. These sunscreens contain ingredients, such as zinc oxide and titanium dioxide, which protect against both UVA and UVB rays. Original formulations of physical sunscreens remained white when applied to the skin. Newer formulations blend more with your skin tone and are less noticeable.
They absorb UV rays before they can cause any damage. They contain one or more ingredients, such as avobenzone or oxybenzone, which absorb UVA or UVB rays. For broad protection, chemical sunscreens often contain more than one ingredient to protect against both UVA and UVB rays. A newer over-the-counter sunscreen contains mexoryl (Anthelios SX) and offers protection against both UVA and UVB radiation.
Sunless tanning products, also called self-tanners, can give your skin a tanned look without exposing it to harmful ultraviolet (UV) rays. Sunless tanning products are commonly sold as creams, gels, lotions and sprays you apply to your skin. Professional spray-on tanning also is available at many salons, spas and tanning businesses.
The active ingredient in most sunless tanning products is dihydroxyacetone (DHA). When applied to the skin, DHA reacts with dead cells in the outermost layer of skin to temporarily darken the skin's appearance. The coloring doesn't wash off, but it gradually fades as the dead skin cells slough off — typically within a few days.
Most sunless tanning products don't contain sunscreen. If you spend time outdoors, sunscreen remains essential.
