Combined Photobiomodulation and Static Magnetic Fields to Reduce Side Effects from Laser and Radiofrequency Treatments for Dermatological Conditions.

Background: Photobiomodulation therapy (PBMT) can significantly reduce inflammation and relieve pain, including postoperative pain and edema. The study aimed to evaluate the performance of a photobiomodulation-based device that includes a static magnetic field (SMF) to treat laser- or intensive and fractional radiofrequency-related side effects, such as pain, redness, and edema in patients treated for different dermatological conditions.

Methods: The study had a prospective, non-randomized, single-center design. Male and female patients aged 18 years or older underwent one or two PBMT-SMF (anti-inflammatory or anti-edematous) sessions on the same day, once or twice a week, after laser or radiofrequency facial treatments due to various dermatological disorders. Variables and efficacy assessments were pain, redness, edema, and their reduction from baseline to the last visit.

Results: Twenty-seven patients were included, seven (25.9%) men and 20 (74.1%) women, with a mean (SD) age of 43.7 (14.1) years. Seven (25.9%) patients were treated with radiofrequency, and 20 (74.1%) patients with a vascular laser (three [15%] for angioma, two [10%] for scars, three [15%] for erythrosis, and 12 [60%] for rosacea). After the PBMT-SMF protocol, overall mean pain reduction was 40 percent, and redness and edema reduction were shown by the pictures taken before and after the PBMT-SMF procedure.

Limitations: The primary limitations were the small number of patients and no quantitative variables for redness and edema.

Conclusion: PBMT-SMF reduced edema and inflammation after treatment with lasers or intensive or fractional radiofrequency for facial conditions, and probably, analgesic and anti-inflammatory drugs.
