Blue light is a non-invasive intense pulse light treatment that uses a specific blue wavelength light to reduce acne-causing bacteria known as Propionibacterium. This blue light also functions to reduce sebaceous gland size and/ or function and has anti-inflammatory properties. Studies show that this wavelength of IPL improves red macules, irregular pigmentation and improves inflammatory acne lesions.
The painless treatment involves a short appointment where blue light IPL is done. Generally, 2-3 sessions per week over a 4-week period is required for blemishes to disappear and skin to regain its normal appearance. Blue light treatment comes with very few side effects and may include slight irritation or redness that resolve quickly.
Blue light treatment has been used safely and effectively in the treatment of acne alone or in combination with topical and some oral medications to synergize their effects. Blue light can also be used in combination with red light therapy and is a great add on to peels and microdermabrasion.
