Is Blue Light Better Than IPL for Treating Acne?

i underwent a few IPL acne treatments and they didn't do anything but cause me pain. Is Blue Light Therapy or some other LED treatment the way to go to get rid of acne?

Blue light for acne

Although FDA has approved Blue Light therapy for acne, our results have been inconsistent. I believe that results are better when Blue light is combined with levulan. However, this is an off label use for Levulan.

There is no head to head comparison of these two treatment modalities. However, I presume that you are referring to the use of these two devices along with levulan or Metvix which helps these modalities work much better, as without application of these agents, the results are not that impressive. I would talk to your dermatologist to see what is best for you, as with various prescription creams, pills (antibiotics, oral contraceptive pill, accutane), chemical peels etc, we now have many options that don't have to break the bank either.

Blue light works better when preceded by Levulan application

Blue light therapy alone can be quite modest in its efficacy for acne treatment. Photodynamic therapy (PDT) using either Blue light and Levulan or Red light and Metvixia works much better in reducing inflammation and minimizing cystic acne lesions. Most experienced board-certified dermatologist would recommend a series of 4 treatments about 2-4 weeks apart. Prepare to experience mild sunburn like redness and peeling for few days after each photodynamic therapy.

Add Levulan to Blue Wavelength IPL

IPL using the blue wavelength is not nearly as effective for acne treatment without the addition of Levulan. Levulan is attracted to the porphyrins produced by the P. Acnes bacteria. When the light source hits the porphrins, the nearby bacteria give up the ghost.

PDT therapy, which this is called, is an excellent adjunct to standard acne treatment. It should not be used in place of it, however.

I do not think L.E. D. treatment has much use in acne therapy.

Blue light VS IPL for Acne

If IPL hasn't been working for you the LED light treatments are always great for acne. 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. We often combine LED Light Therapy with other treatments, such as medical facials and/or chemical peels, for even more dramatic results, customized for each patients’ needs. Another laser option is the Smoothbeam, the only FDA approved laser for treatment of acne on the face and body. Also treats acne scars. This treatment has no pain and no downtime. This is an excellent treatment for hard to treat acne.

Blue Light Therapy for Acne

Yes, blue LED light therapy would be a better option for treating acne than the IPL.  IPL is only effective for acne when used to activate a photodynamic therapy solution such as Aminolevulinic Acid.  Blue LED light therapy however can be very effective even when used independently from other therapies.  The wavelength of the blue LED light works to kill the p.acne bacteria that causes 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.
