Dr. Bosley appeared on WFAA’s Good Morning Texas to expand on sunscreen concerns and common misconceptions. May 30, 2019. For sun spots we do offer some treatments here at Prism Dermatology including Photofacials and ResurfX to help rejuvenate that skin. To prevent damage, use at least SPF 30 or SPF 45+ for full sun environments.
And here is Dr. Bosley’s 2020 sunscreen tips for WFAA:
What sunscreen should I use?
The American Academy of Dermatology recommends everyone use sunscreen that offers the following:
- Broad-spectrum protection (protects against UVA and UVB rays) SPF 30 or higher, water resistance sunscreen that offers the above helps to protect your skin from sunburn, early skin aging and skin cancer. However, sunscreen alone cannot fully protect you. In addition to wearing sunscreen, dermatologists recommend taking the following steps to protect your skin and find skin cancer early:
- Seek shade when appropriate, remembering that the sun’s rays are strongest between 10 a.m. and 2 p.m. If your shadow is shorter than you are, seek shade.
- Dress to protect yourself from the sun by wearing a lightweight long-sleeved shirt, pants, a wide-brimmed hat and sunglasses, when possible.
- Use extra caution near water, snow, and sand as they reflect the damaging rays of the sun, which can increase your chance of sunburn.
- Get vitamin D safely through a healthy diet that may include vitamin supplements. Don’t seek the sun.
- Avoid tanning beds. Ultraviolet light from the sun and tanning beds can cause skin cancer and wrinkling. If you want to look tan, you may wish to use a self-tanning product, but continue to use sunscreen with it.
- Check your birthday suit on your birthday. If you notice anything changing, itching, or bleeding on your skin, see a board-certified dermatologist. Skin cancer is highly treatable when caught early.
When should I use sunscreen?
Every day if you will be outside. The sun emits harmful UV rays year-round. Even on cloudy days, up to 80 percent of the sun’s harmful UV rays can penetrate your skin.
Snow, sand, and water increase the need for sunscreen because they reflect the sun’s rays.
Is a high-number SPF better than a low-number one?
Dermatologists recommend using a sunscreen with an SPF of at least 30, which blocks 97 percent of the sun’s UVB rays. Higher-number SPFs block slightly more of the sun’s UVB rays, but no sunscreen can block 100 percent of the sun’s UVB rays.
It is also important to remember that high-number SPFs last the same amount of time as low-number SPFs. A high-number SPF does not allow you to spend additional time outdoors without reapplication. Sunscreens should be reapplied approximately every two hours when outdoors, even on cloudy days, and after swimming or sweating, according to the directions on the bottle.
