Abstract
Background: Patients with rosacea and demodicosis have high facial skin Demodex densities (Dds), which decrease with benzyl benzoate (BB) treatment.Objectives: To evaluate the impact of topical BB (+crotamiton) treatment on Dds and clinical symptoms during prolonged follow-up and to compare low (12% once daily) and high (12% twice daily or 20-24% once daily) BB dose regimens.Methods: This retrospective study included 344 patients (103 rosacea, 241 demodicosis) observed for 7.1 ± 0.5 months. Dds were measured on two consecutive standardized skin surface biopsies and symptoms evaluated using investigator global assessment. Compliance was considered good if patients correctly followed treatment instructions.Results: At final follow-up, in the 248 patients with good compliance, Demodex density had normalized in 217 (88%) and symptoms cleared in 204 (82%). The high dose was associated with better compliance and faster results than the low-dose. The higher the initial Dd, the longer it took to normalize. In the 96 poorly compliant patients, treatment was less effective and slower.Conclusion: These findings indirectly support a key role of the mite in rosacea and suggest that topical treatment with BB (+crotamiton), especially the higher dose, may be a useful alternative treatment for rosacea as well as for demodicosis.
