To improve patient care and outcomes, leading dermatologists from the Cutis Editorial Board answered 5 questions on sunscreens. Here’s what we found.
What sun protection factor (SPF) do you recommend for the majority of your patients?
Fifty percent of dermatologists we surveyed recommend SPF 30. SPF 50 was recommended by 26%, SPF 50+ by 21%, and SPF 15 by only 2%.

Half of our Editorial Board recommends sunscreen with SPF 30, with many recommending SPF 50 or higher. This trend toward sunscreens with higher SPF is consistent with a survey-based study with 97% of dermatologists stating they were comfortable recommending sunscreens with an SPF of 50 or higher and 83.3% stating that they believe that high SPF sunscreens provide an additional margin of safety (Farberg et al). These trends are supported by a randomized, double-blind, split-face clinical trial in which participants applied either SPF 50+ or SPF 100+ sunscreen after exposure to natural sunlight. The results showed that SPF 100+ sunscreen was remarkably more effective in protecting against sunburn than SPF 50+ sunscreen in actual use conditions (Williams et al).
