Body Care: Sunscreen
What is Sunscreen?
Sunscreen is a lotion, spray, gel, or other topical product that helps protect the skin from the sun’s harmful ultraviolet (UV) rays. UV rays can cause sunburn, premature aging, and even skin cancer.
Sunscreen works by absorbing or reflecting UV rays before they can reach the skin. It is important to use sunscreen every time you are exposed to the sun, even on cloudy days.
Types of Sunscreen
There are two main types of sunscreen:
* Chemical sunscreens: Chemical sunscreens contain ingredients that absorb UV rays and convert them into heat. This heat is then dissipated through the skin. Chemical sunscreens are typically more effective at blocking UV rays than physical sunscreens, but they can also be more irritating to the skin.
* Physical sunscreens: Physical sunscreens contain ingredients that reflect UV rays away from the skin. Physical sunscreens are typically less effective at blocking UV rays than chemical sunscreens, but they are also less likely to irritate the skin.
How to Choose a Sunscreen
When choosing a sunscreen, it is important to consider the following factors:
* SPF: SPF (sun protection factor) is a measure of how well a sunscreen protects the skin from UVB rays, the rays that cause sunburn. The higher the SPF, the more protection the sunscreen provides.
* Broad spectrum: Broad spectrum sunscreens protect the skin from both UVA and UVB rays. UVA rays cause premature aging, while UVB rays cause sunburn.
* Water resistance: Water resistance is a measure of how long a sunscreen will remain effective after being submerged in water. Sunscreens with a higher water resistance rating will stay effective for longer periods of time.
* Type: Sunscreens come in a variety of forms, including lotions, sprays, gels, and sticks. Choose a form that is easy to apply and that you will be comfortable wearing.
How to Apply Sunscreen
To apply sunscreen effectively, follow these steps:
1. Apply sunscreen to all exposed skin, including the face, neck, hands, and feet.
2. Apply sunscreen liberally, using about an ounce for the average adult.
3. Rub sunscreen in thoroughly.
4. Reapply sunscreen every two hours, or more often if you are swimming or sweating.
Tips for Using Sunscreen
* Apply sunscreen every day, even on cloudy days.
* Apply sunscreen at least 30 minutes before going outside.
* Reapply sunscreen every two hours, or more often if you are swimming or sweating.
* Avoid using sunscreen with an SPF of less than 30.
* Use a broad spectrum sunscreen that protects against both UVA and UVB rays.
* Choose a sunscreen that is water resistant for at least 80 minutes.
* Store sunscreen in a cool, dark place.
Conclusion
Sunscreen is an important part of a healthy skin care routine. By using sunscreen every day, you can help protect your skin from the sun’s harmful rays and reduce your risk of skin cancer.
