Moderating sun exposure and using sunscreen are two of the best ways to keep your skin healthy and to minimize your risk for skin cancer.
OVEREXPOSURE TO THE SUN IS THE PRIMARY CAUSE OF AGING SKIN
If you want to maintain a youthful appearance, you must protect your skin from the sun.
- Avoid suntanning.
- Wear sun screen (SPF 30 or higher) that blocks UVA and UVB rays whenever you are out in the sun.
- Sunscreens are the best “anti-aging” products currently available.
How Sunscreens Work
Sunscreens absorb or reflect ultraviolet rays. Both zinc oxide and titanium dioxide reflect or scatter UV radiation. Octyl methoxycinnamate (OMC) and oxybenzone absorb radiation, dispersing it as heat.
Use a broad-spectrum sunscreen that protects against the two types of damaging UV radiation: UVA (causes tanning) and UVB (causes sunburns).
SPF refers to the sun protection factor in sunscreens.
An SPF of 8 blocks almost 90 percent of UVB rays.
An SPF 15 blocks 93 percent of UVB and some UVA rays.
An SPF of 30 blocks 96 percent of UVB and some UVA rays.
Additional Ways To Avoid Skin Damage
- Wear protective clothing, such as a long sleeved shirt, pants, a wide brimmed hat and sunglasses.
- Look for shady areas. The sun’s rays are strongest between 10 am and 4pm. If your shadow appears to be shorter than you are, seek shade.
- Use extra caution near water, snow and sand because they reflect and intensify the damaging rays of the sun, which can increase your chances of sunburn.
- Avoid tanning beds. Instead, try a sunless, self-tanning product, but continue to use sunscreen daily.
- Eat a diet rich in fruits and vegetables. They provide antioxidants, which may help protect cells from free radical damage that occurs when UV rays from the sun are absorbed by our skin.
