Lots of people know that prolonged sun exposure is bad for the skin. However, not a lot of people protect their skin with sunscreen because they don't really know what it's for or how it works. Here are 3 things you need to know about sunscreen:
1) IT PREVENTS SKIN CANCER
Sunscreen protects the skin from ultraviolet rays. There are 2 types of UV rays: the UVA and UVB. Both rays contribute to skin cancer development. Sunscreen must be worn all the time, all year round!
2) IT PREVENTS PREMATURE AGING
Prolonged sunscreen application prevents lines, skin coarseness, and age spots, which are well known symptoms for aging.
3) IT PREVENTS SUNBURNS
Wearing sunscreen prevents sunburns and its long-term side effects.
The skin reddening, swelling and peeling of a sunburn reflect widespread damage to your skin cells in response to prolonged exposure to UV rays. Sunburns can cause permanent skin damage that increases your risk for skin cancer. Each severe sunburn throughout life increases the risk for melanoma, the most serious form of skin cancer.
HOW TO CHOOSE THE RIGHT SUNSCREEN
- Look for a sunscreen that offers broad-spectrum UV coverage and has a sun protection factor (aka. SPF) of at least 15.
- Refer to the label to find whether you must reapply the product every 40 or 80 minutes while swimming or sweating.
