Treatment Tech: Light Therapy
Red Light Therapy is one of the fastest-growing, noninvasive treatments in the beauty industry. As skin experts, we’re using other wavelengths like blue, green, and yellow or combinations like red & blue together, which studies show far more effective than blue light alone for acne.
Compared with blue light phototherapy, benzoyl peroxide, and white light control, blue-red light phototherapy is associated with more significant improvement in inflammatory lesions and results in a lower comedone count.
The incidence of patient reports of dryness/itch was significantly less for blue-red light phototherapy compared with the other modalities which makes Light Therapy a great addition to existing treatment programs.
