Keratosis Pilaris: Treatment Practices of Board-Certified Dermatologists.

Keratosis pilaris (KP) is a chronic disorder of follicular hyperkeratinization and perifollicular erythema with lesions affecting the extensor surfaces of arms, upper legs, and buttocks. While there is some evidence that laser therapies and topical therapies such as lactic acid reduce the follicular papules of KP, support is limited with respect to which topical treatments dermatologists utilize and their perception of efficacy. A 16-question survey was distributed to a random sampling of the ODAC Conference listserv to determine which topical treatments dermatologists utilize the most, the duration of therapy needed with various treatment modalities, and the effectiveness of topical and laser therapy for treating KP. Our study found topical lactic acid is the most used first-line therapy for KP (43.63% of survey respondents), followed by salicylic acid (20.72%). Laser therapy is only utilized by 8.76% of survey respondents, with a lack of insurance coverage and proper equipment limiting its use. KP is often recalcitrant to treatment, and our study demonstrated that over 60% of respondents found recurrence of KP lesions within three months of stopping salicylic acid treatment and OTC moisturizer treatment. The data herein can be used to better utilize the selection of topical and laser therapies for the treatment of KP. J Drugs Dermatol. 2023;22(10):985-989 doi:10.36849/JDD.7534.
