مقایسه‌ی دو کرم ضدآفتاب در پیش‌گیری از آفتاب‌سوختگی

Background and Aim: Considering the prevalence of sunburn and its complications and the importance of preventing it, we conducted a study to compare a brand sunscreen with SPF = 60 (cream A) and a domestic sunscreen with SPF = 50 (cream B) in hikers. Methods: The clinical trial was carried out on 50 participants in shiraz. 0.4 ml of the cream A was applied to one side of face and the same amount of cream B was applied to other side as control. The participants were exposed to the sun for 5 hours. The assessment was performed 3 hours after the onset by a dermatologist and 24 hours later by the participants themselves based on erythema, burning, itching and satisfaction with the products. The data were analyzed using McNemar and chi-square tests. Results: Cream B in 82.2% and A in 76.2% of cases prevented sunburn. Also, the participants' satisfaction was 95% and 82% for using B and A creams, respectively. Sunscreen A and B did not show significant difference in prevention of sunburn, but side effects such as burning and itching were observed more in cream A and paricipants satifaction was more with cream B. Conclusion: Overall cream B had less side effects and participants were more satisfied with it.
