Best Rx: Marietta Dermatology & The Skin Cancer Center

Dr. Robert M. Harper from Marietta Dermatology & Skin Cancer Center answers a reader’s question about sunscreen selection:

Q: What should I look for in a sunscreen? I apply first thing every morning but am still getting color and areas of discoloration.

A: When selecting a sunscreen, look for a product that states on the bottle “UVA/UVB broad-spectrum coverage of at least 30+.” Another significant fact is that the ingredients needed to maintain the integrity of coverage only last approximately three to three and a half hours, so reapplication is key even on overcast days, as the sun is always shining. Also remember sunscreen should be applied 15 to 20 minutes prior to sun exposure for optimum results and to prevent further sun damage to the skin.
