Patients diagnosed with post-inflammatory hyperpigmentation, men, and those with disease duration <1 year reported lower sunscreen usage, a recent study found. These groups might benefit from increased counseling on sun-protective behaviors. Researchers conducted a cross-sectional study with 404 adults who complained of cutaneous hyperpigmentation. They found:

• About 67.5% reported using a product containing sunscreen, and 91% endorsed using one with a sun protection factor of ≥21.
• Among the participants, 48.5% were not sure if their sunscreen provided broad-spectrum protection, and only 7.6% reapplied every 2 hours.
• The odds of a patient with melasma using sunscreen were 6.7 times the odds of a patient with post-inflammatory hyperpigmentation using sunscreen.
• Additional predictors for sunscreen use were female sex and disease duration of ≥1 year.
• In a multivariate analysis, the odds ratio of sunscreen use among African Americans compared to whites was 0.31.
