Important Tips for Buying and Wearing Sunscreen
According to Women’s Health magazine, there are six potentially harmful ingredients that you should avoid:
- Retinyl Palmitate (Vitamin A Palmitate)
- Paraben Preservatives
You should look for labels that say broad spectrum, SPF 20 or higher, or skin cancer or skin aging alert. Broad spectrum means the sunscreen lotion will protect your skin from ultraviolet A (UVA) and ultraviolet B (UVB) rays, both of which can cause cancer.
UVA rays cause premature aging and can pass through glass. UVB rays cause sunburn and cannot. Sun Protection Factor (SPF) is a number that indicates how well your sunscreen will guard you from sunburn (UVB rays). So if you’re using and SPF 30 sunscreen, that means you get 30 times the amount of sun protection than your normal amount of protection.
Everyone needs sunscreen, regardless of age, gender or ethnicity. The sun’s harmful ultraviolet rays can lead to various skin cancers, the deadliest form being melanoma. Over their lifetime, 1 in 5 Americans will develop skin cancer.
When Should I Reapply Sunscreen?
This depends on how long you normally start to burn, but for instance, if you burn in 10 minutes, this is how you can figure out when to reapply.
Equation: Normal burn time X SPF rating = Total minutes of protection
SPF 15 – reapply after 150 minutes (10 minutes X 15)
SPF 30 – reapply after 300 minutes (10 minutes X 30)
PRO TIP: Every two hours, or so, reapply. When using water-resistant sunscreen, reapply after leaving the water or sweating, for maximum effectiveness.
