Sun Protection Tips from Dr. Kenneth Mark
With the recent FDA regulations, we wanted to offer some sunscreen tips for your consideration from board-certified cosmetic dermatologist and fellowship-trained Mohs skin cancer surgeon, Dr. Kenneth Mark. Dr. Mark is a credible expert with four prestigious practices, including two in the Hamptons (he is celebrating his 10th-year anniversary practicing in East Hampton and Southampton this summer), one in Aspen, and one in NYC. He is also a clinical assistant professor of dermatology at New York University.
TIP 1: New FDA regulations on sunscreen
o The main benefit of the new FDA regulations is that there will be increased knowledge and transparency to the consumer for the UVA protection in products and education of SPF designations, which only addressed UVB protection
o Since SPF designation relates to UVB protection from getting a sunburn, these new regulations help consumers understand that it is actually the UVA rays which penetrate the skin deeper and cause harmful effects on the skin, from aging to cancer.
TIP 2: How often should you apply sunscreen
o When in direct sunlight (at the beach, outside), apply sunscreen at least every two hours. If you are sweating or swimming, reapply every 30 minutes after significant water exposure.
o When you are in and out of the sun, apply your sunscreen two or three times throughout the day.
TIP 3: What are the most important ingredients to look for in a sunscreen
o You should always use a sunscreen with a physical blocker, such as zinc oxide and titanium dioxide (both work to block out full UVA and UVB spectrum).
o Most sunscreens have excellent UVB protection, so with products that don’t have those physical blockers, look for UVA-blocking chemicals, including:
– Parsol 1789 (a.k.a. Avobenzone)
TIP 4: What sunscreens are recommended
o Z-Silc has a wonderful sunscreen that has a full range of UV protection and rubs in smoothly.
o I would also recommend Neutrogena Ultra Sheer Body Mist, which contains Helioplex.
