Dr. James Nordlund Discusses What Number SPF to Use

Group Health physician James J. Nordlund, MD, recently discussed sunscreens on WKRC-TV's Ask the Expert segment. He reported that suncreen standards will be changing in the fall, with the new numbers ranging from SPF 15 to SPF 50. Dr. Nordlund pointed out that a higher SPF number doesn't provide significantly more protection. Instead, applying the sunscreen frequently would be more important, he said.
