A study performed on 10 patients (9 females and 1 male, aged between 30 and 45 years) affected by papulo-pustular rosacea has been released. All patients were treated with topical 0.75% metronidazole and with systemic tetracyclines or clarithromycin until complete or almost complete resolution of the papulopustular lesions. Patients were then treated with a series of 3–4 peelings with a 25% salicylic acid solution performed at 3–4 weeks intervals. Complete resolution of the remaining inflammatory lesions and improvement of erythrosis was obtained in all the patients. Salicylic acid penetrated more deeply in the areas of inflammation which showed decreased erythema; papule and pustules were rapidly dried at 1 or 2 days after the peeling. These beneficial aspects of salicylic acid peeling are probably determined by the antimmicrobic activity of salicylic acid which also stimulates fibroblasts inducing an improvement of the vascular component of rosacea.
