What SPF stands for?
You may have seen the letters SPF on sunscreen bottles and thought the higher the sunscreen, the better it protects your skin. SPF stands for Sun Protection Factor to protect against UVB, which is the type of ultraviolet radiation that causes sunburns and sometimes cancer.
SPF levels range between 15 to 50. SPF 15 means it will block approximately 93 percent of UVB rays. SPF 50 means it will block approximately 98 percent of UVB rays.
SPF also helps protect your skin for a certain amount of time, depending on how sensitive it is and how fast it normally burns without sun protection. For example, if your skin is very sensitive and can burn within 5 minutes of being exposed to the sun without sunscreen, it can take 75 minutes to get a sunburn if using SPF 15. An application of SPF 30 means it would take at about 150 minutes of sun exposure before reaching the sunburn stage.
Can Sunscreen Prevent Wrinkles?
UVA, known as the ultraviolet rays that cause wrinkles, age spots, and increases the chances of skin cancer, can be blocked by broad spectrum sunscreen lotions. UVA can accelerate the appearance of wrinkles, but helping to shield it can’t slow it down. It can just help keep it from showing up sooner.
A Helpful Tip on Sunscreen Application
If you know you might be out in direct sunlight for a long period of time, an added application of sunscreen should be considered. In fact, skin experts recommend re-application every 2 hours due to the possibility of it rubbing off or just not working as effectively.
Are There Dangers to Using Sunscreen?
If used in moderation, most sunscreens can be quite safe. However, if you’re a health conscious individual, you might consider minimal use if it contains any of the following ingredients:
- retinyl palmitate
- titanium dioxide
- Vitamin A
Now, are you ready for some sunshine? be sure to have some broad spectrum sunblock on!
