Blue Light Therapy for Acne treatment
We use different light wave therapies—either separately or together to achieve optimal, customized results:
Red light therapy: Activates collagen production to improve the visible signs of aging, to restore glowing, healthy-looking skin. It can also be used to reduce age spots, sun damage, and overall redness, flushing, and dilated capillaries. Red light therapy can also reduce the appearance of bruising and reduce healing time. Results are often immediate.
Blue light therapy: Kills acne-causing bacteria, without harming skin, to improve skin clarity and reduce future breakouts. Results are often seen after just one treatment.
Blue light therapy works!
Blue Light Therapy is performed using a blue LED (light emitting diode) Light. The wavelength of the blue LED works to kill the p.acne bacteria implicated in acne, therefore reducing acne lesions.
This is a painless and extremely effective procedure.
I recommend having treatments about 1-2 times a week for 6 treatments. Some patients may require more treatments depending on the severity of their acne.
Unfortunately blue light therapy will not help with acne scarring. One would want to consider chemical peels, microdermabrasion or Mixto laser resurfacing to improve acne scars.
Blue Light Therapy kills Acne Bacteria
Blue light therapy is a safe, effective option for inflammatory acne (red pimples, pus bumps). It can be considered a safe, long acting alternative to antibiotics. The spectrum of light (411nm) used with blue light therapy activates a chemical compound (porphyrins) found in the bacteria associated with acne (p. acnes bacteria). This chemical activation ultimately results in the death of the bacteria.
Results usually take 6-8 weeks to see their full effect, but results may last for up to 9-10 months. It is still wise to continue topical therapies during and after Blue Light therapy ot maximize and extend these results. It is very safe and comfortable treatment.

Blue Light treatments can help acne
The Blu-U and other Blue Light devices like it help with acne by killing acne bacteria. We use the Blue Light treatments in combination with ALA (amino levulanic acid) for the treatment of severe acne to shrink the sebaceous (oil) glands. This treatment is typically used by our patients as an alternative to Accutane.
Blue Light treatments will not help with acne scars.
BLU-U light therapy more useful when preceded by Levulan, namely Photodynamic Therapy (PDT)
The advantage of BLU-U light therapy is attributed to absolutely no downtime. However, BLU-U as a stand alone therapy is mildly helpful for acne and not at all for acne scarring.
On the other hand, photodynamic therapy (PDT) which is BLU-U, preceded by Levulan (a metabolite of hemoglobin in red blood cells) application can be a very useful adjunct for resistant inflammatory acne vulgaris as there has been documented eradication of bacteria responsible for triggering inflammatory acne as well as reduction of sebum production.
Typically, one may benefit from a series of 4 PDTs, 2-4 weeks apart with increasingly more aggressive protocol involving combination of incubation time (the duration Levulan is left on the skin) and exposure time (the duration in front of the BLU-U light).
