TLDR The 755-nm alexandrite laser effectively and quickly treats trichostasis spinulosa with minimal pain and no side effects.
The study reported the successful treatment of trichostasis spinulosa (TS) in 20 patients using a short-pulsed 755-nm alexandrite laser. All patients, with skin types II–V, had TS lesions on the tip of their nose and received a single treatment with the laser. The procedure, which took less than 5 minutes, involved one to three passes with cold air cooling and no anesthesia. The treatment parameters were a pulse duration of 0.5 ms, fluence of 15–17 J/cm², and a spot size of 5 mm. The lesions disappeared immediately after treatment with minimal or no pain, and erythema lasted only 5–20 minutes. Patients were very satisfied, and the treated areas remained clear for 4 to 5 weeks, with no recurrence or adverse effects observed during the 3-month follow-up period. This laser treatment was found to be rapid, minimally painful, and effective for TS in patients with skin types II to V.
