“…Recently, several clinical studies have shown that heat may be beneficial for acne [67][68][69][70], which raises a possibility for our subjects to have benefited from the mild heat from the LED device. However, the devices used in those studies were specifically designed to deliver thermal energy to the dermis while used in contact with the skin surface, whereas the one used for our study was equipped with cooling fans to avoid heat generation, consisted of LEDs which have low heatemitting property, and was positioned 3-5 cm above from the skin surface during the treatment.…”

Background and Objectives: Blue light is effective for acne treatment, inducing photodynamic destruction of Propionibacterium acnes (P. acnes). This study was designed to investigate the efficacy of combined blue and red light-emitting diode (LED) phototherapy for acne vulgaris. Materials and Methods: Twenty-four patients with mild to moderately severe facial acne were treated with quasimonochromatic LED devices, alternating blue (415 nm) and red (633 nm) light. The treatment was performed twice a week for 4 weeks. Objective assays of the skin condition were carried out before and after treatment at each treatment session. Clinical assessments were conducted before treatment, after the 2nd, 4th, and 6th treatment sessions and at 2, 4, and 8 weeks after the final treatment by grading and lesion counting. Results: The final mean percentage improvements in noninflammatory and inflammatory lesions were 34.28% and 77.93%, respectively. Instrumental measurements indicated that the melanin levels significantly decreased after treatment. Brightened skin tone and improved skin texture were spontaneously reported by 14 patients. Conclusion: Blue and red light combination LED phototherapy is an effective, safe and non-painful treatment for mild to moderately severe acne vulgaris, particularly for papulopustular acne lesions.

“…Photodynamic therapy, using a variety of visible wavelengths and a number of photosensitizing dyes, has been used to treat acne [17,18]. In addition to visible wavelengths of light, radiofrequency has also been used to treat acne [22]. Recently, the most commonly used laser modalities for treating acne with electromagnetic radiation are the infrared lasers [23][24][25][26][27][28][29].…”

Background and Objectives: Laser treatment using a 1,450 nm diode laser has been shown to improve acne and acne scarring. Its widespread adoption in younger populations has been significantly limited by discomfort. Study Design/Materials and Methods: Six subjects with active papular acne were treated in a pilot study to determine parameters for a split-face, double-pass, lowenergy protocol of 1,450 nm laser treatment. Sides of the face were randomized to receive single-pass, high-energy treatment (13-14 J/cm 2 ), or double-pass, low energy treatment (8-11 J/cm 2 ), for a total of four treatments delivered at monthly intervals. Acne counts and standardized, digital photograph were performed 2 months following the final treatment, and compared to pre-treatment counts and photographs. Results: Improvement was evaluated comparing pre-and post-treatment photos and averaged 2.5 for the highenergy, single-pass side and 2.3 for the low-energy, double-pass side, using a 0 (worse) to 4 (max improvement) scale. Acne counts were reduced 78% on the high-energy, single-pass side and 67% on the low-energy, double-pass side. Pain ratings on a 1 (min) to 10 (max) scale averaged 5.6 (range 1-9) for the high-energy, single-pass side and 1.3 (range 1-2) for the low-energy, double-pass side. Conclusions: Low-energy, double-pass 1,450 nm laser treatment effectively reduces acne counts 2 months posttreatment, and dramatically reduces the pain associated with treatment. The treatment parameters used in this study have eliminated the need for anesthetic cream in daily practice.

“…[1][2][3]6,7 Recently, nonablative lasers, light sources, and radiofrequency devices have been used to selectively deliver thermal energy to the upper dermis, inducing a controlled wound healing response in the papillary and upper reticular dermis without epidermal damage. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Histologic studies have confirmed production and deposition of new collagen after thermal damage induced by nonablative laser treatments. 10,14,18 Although previous studies have shown that nonablative laser treatments result in qualitative improvements in facial rhytids and scars, there has been an inherent difficulty in quantifying the effects of nonablative resurfacing.…”

Nonablative Radiofrequency for Active Acne Vulgaris: The use of Deep Dermal Heat in the Treatment of Moderate to Severe Active Acne Vulgaris (Thermotherapy): A Report of 22 Patients

Abstract: Nonablative radiofrequency appears to be a new safe and effective treatment alternative for moderate to severe acne vulgaris. Further research is in progress to evaluate this treatment modality in a larger number of patients.
