WHY YOU NEED SUNSCREEN?

Updated: Jul 4

"Many behaviors can be adopted in order to reduce sun exposure and help prevent skin cancer, such as using waterproof sunscreen with a sun protection factor (SPF) of 15 or higher, repeatedly applying the sunscreen."--Research


Everyone knows the harmful effects of the sun. It causes skin cancer, aggravates allergies, causes wrinkles, and even changes our hair color. That does not mean you have to sacrifice going to the beach or going somewhere to have fun. Use sunscreen.


Sunscreen reduces or eliminates sunburn. Sunscreens are formulated to block both UVA and UVB: the two main causes of skin cancer. Choose a high SPF sunscreen that leaves your skin feeling cool, not burned. Wear sunscreen while being outdoors, even on cloudy days. Note that by applying sunscreen to your face, body, and neck, you are reducing your exposure to UV rays but not eliminating them.


"Skin cancer accounts for about 40% of all cancers, and approximately one in five Americans develops skin cancer in his or her lifetime. Because exposure to the sun's ultraviolet rays is responsible for more than 90% of all skin cancers (The Skin Cancer Foundation, 1995), many behaviors can be adopted in order to reduce sun exposure and help prevent skin cancer, such as using waterproof sunscreen with a sun protection factor (SPF) of 15 or higher, repeatedly applying the sunscreen."--Message Framing and Sunscreen Use: Gain-Framed Messages Motivate Beach-Goers, Health Psychology

Moreover, sunscreen prevents blistering and cracking. Sunscreens with a high sun protection factor (SPF) will provide some protection against sunburn. They also prevent oil from clogging in your pores and irritate your skin's surface.


Be aware, though, that some sunscreen may cause sun sensitivity. Some people develop sun sensitivity after only wearing sunscreen for a short time. Other people develop redness or irritation right from the start. If you develop a sensitivity, consult your dermatologist. Most sunscreens have been approved by the Food and Drug Administration (FDA).
