Intense pulsed light (IPL) devices can be used in acne treatment in combination with conventional topical and oral medications. 

A new study published in Lasers in Medical Science evaluated the efficacy and safety of IPL therapy, using a dual-band filter – 400-600 nm and 800-1200 nm, in facial acne vulgaris treatment.

The present study recruited 23 patients with acne vulgaris, who were treated on both sides of the face. Treatments were performed in 2-week intervals for a total of five sessions. The final visit for the clinical evaluation was 2 weeks after the fifth treatment session. 

It was noted that the mean number of papules, pustules and comedones, and the melanin index, was significantly reduced at the final visit of patients. However, sebum production and the erythema index showed no statistically significant differences after treatment. 

From the results, it was inferred that IPL treatment using a dual-band filter can be an alternative for patients who are unfit for systemic acne medication. Furthermore, it can be used with conventional acne treatment for better treatment results.
