Study summary

Malassezia folliculitis is a common dermatological disorder. While antifungal agents generally demonstrate efficacy in application, the prevalence of recurrence and drug resistance remains a common occurrence. Supramolecular salicylic acid represents a novel class of superficial chemical peel agents, exhibiting keratolytic, anti-inflammatory, and bacteriostatic properties. Zinc pyrithione has broad spectrum antibacterial, antifungal, and anti-inflammatory effects. In the present study, investigators evaluated the clinical efficacy of topical application of supramolecular salicylic acid in combination with zinc pyrithione for the treatment and prevention of Malassezia folliculitis recurrence. All data are recorded and compared after the end of the experiment. The enrolled patients received daily application of topical supramolecular active zinc anti-dandruff lotion, in conjunction with weekly application of 30% supramolecular salicylic acid, for a duration of 8 weeks. Lesion counts, Malassezia detection, clinical symptom scores, patient satisfaction, and side effects were recorded at each visit till the week 12.

What researchers measure

Primary outcomes

  1. lesion counts

    The counts of skin lesions, including papules, pustules, and papulopustules.

    Time frame: From enrollment to week 12

  2. The reduction rate of lesion counts

    The reduction rate expressed as (lesion counts at baseline - lesion counts at 8 weeks)/lesion counts at baseline×100%.

    Time frame: From week 1 to week 12

  3. Clinical efficacy

    The clinical efficacy after the treatment was classified as follows: clinical cure (refers to lesion reduction rate of 100%, negative Malassezia detection), obvious improvement (refers to lesion reduction rate of 70-99%, positive or negative Malassezia detection), moderate improvement (refers to lesion reduction rate of 30-69%, positive or negative Malassezia detection), and no improvement (refers to lesion reduction rate \<30%, positive Malassezia detection).

    Time frame: week 8 and week 12

Secondary outcomes

  1. Clinical symptoms scores

    The degree of clinical symptoms, including pruritus, scale, greasiness, and erythema, was classified as 0 (none), 2 (mild), 4 (moderate), 6 (severe).

    Time frame: From enrollment to week 12
