Therapeutic Approach

Keratosis pilaris (KP) is a common condition characterized by keratotic, follicular papules with varying degrees of surrounding erythema. It most often affects the lateral face, extensor arms, and thighs and is prevalent in children. Although KP can improve by late adolescence, it persists into adult life in at least one-third of patients. Patients (or their parents) should be counseled about the benign nature of KP, and expectations should be tempered as treatment may minimize the symptoms temporarily but does not eradicate the condition. In the author’s experience, simple measures such as avoiding drying or irritating skin care products and the frequent use of bland emollients are reasonable first steps, especially in young children. Patient age, motivation, and tolerance of adverse effects are factors to consider when choosing therapy. Keratolytics are usually initiated if emollients are not sufficient. Cost and inconsistency and/or impermanence of outcomes limit the utility of procedural interventions for KP. Studies of treatments for KP tend to be limited by low numbers of patients, combinations of several treatments, and heterogenous assessment of outcomes, making the overall quality of evidence low to moderate.1 See Table 35-1.
