Light Therapy in the Treatment of Acne Vulgaris

In recent years, a number of studies have evaluated the treatment of acne using electromagnetic waves, such as lasers, photodynamic therapy, visible light or radio waves. While the efficacy of laser treatment is still uncertain, photodynamic therapy shows promising results, but with marked side-effects, as destruction of sebaceous glands. Treatment with blue light (405-420 nm wavelength) also appears effective and can be regarded as an treatment option for inflammatory acne.

“…Despite a wide variety of treatment options, there is a growing demand among both patients and practitioners for fast, safe, and side-effect-free interventions [8]. Various forms of phototherapy with visible light have been shown to be effective in the treatment of acne vulgaris [9].…”

“…Absorption of the appropriate wavelength of light energy causes the creation of a highly reactive free radical species leading to the destruction of the bacterial cell wall [10]. Infrared laser light selectively targets the dermal layer where sebaceous glands are located [8]. The heat from the absorbed energy creates thermal injury and alters the structure of the sebaceous glands.…”

Background: At-home phototherapy devices for the treatment of acne have emerged as an appealing treatment option and as an effective adjunct treatment to existing modalities. The principal goal of the study was to determine the changes in the number of inflammatory lesions in acne patients. Methods: Patients received instruction for daily at-home use of Silk'n Blue device for 12 weeks. Follow-up visits were conducted at 1 and 3 months to collect data. Results: Fifteen subjects with mild to severe cases experienced improvement over the course of the trial. The decrease in mean inflammatory acne counts (from 41.26 to 24.46) and mean percent reduction (41.8%) were statistically significant (p < 0.001). Some participants experienced percent reductions as great as 67%. No adverse events were recorded. Conclusions: The Silk'n Blue device is a safe and effective modality for at-home treatment of mild, moderate, and severe inflammatory acne vulgaris with proper use.

“…Although absorption and photodynamic excitation are most efficient between the wavelengths of 400 and 430 nm, with enough light, the reaction may be initiated with a variety of different wavelengths. Factors that influence P. acnes photoinactivation and thus act as parameters for laser/ light-based therapies include porphyrin concentration (depending on acne lesion type), effective fluence, wavelength of the emitted photons, and temperature at which the reaction is carried out [18].…”

Over the last two decades, lasers and light-based therapies have been developed to treat a wide variety of cutaneous maladies. Given the prevalence and number of patients who suffer from refractory acne, alternatives to existing care are constantly sought after. In this review, we discuss the evidence currently available to justify the use of laser and light-based modalities and conclude that in combination therapy, such approaches provide a safe and effective treatment for acne vulgaris.
