Does LED Work for Acne Treatment?

Acne - can't stand that nothing is working to reduce it.  I read about LED light treatments and that could work on acne, but  not  going that direction unless someone can tell me it works.  too expensive and time consuming if not.

LED Light Therapy is a light treatment that can be used to stimulate collagen production (reducing fine lines and wrinkles) and kill acne-causing bacteria on the skin, improving skin clarity—with no pain and no downtime.
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 LED works to improve acne

I have found LED blue light therapy very effective for treating acne but it does require multiple treatments.

LED light treatments in our practice are $35 per session and only $25 per session if done with another service such as a deep cleansing facial.

Typically patients will come in for two treatments a week for 3-4 weeks or until improvement is visible. At that point we gradually decrease the frequency of treatments. The treatment only takes about 20 minutes and does not leave any visible signs that you have had a treatment done.

I am only familiar with the Gentle Waves LED. I think it is excellent for post procedure treatments. It seems to really calm the skin. Gentle Waves generally gives the skin a nice tone and texture. Patients look more relaxed and healthier.

However, it does not satisfactorily addressall the causes of acne: sticky, plugged pores, bacterial overgrowth in the pores, excessive sebum output and the subsequent inflammation. It only works on the latter. So while it might be somewhat helpful in acne, there are far far more effective treatments available.

L.E.D.( Light Emitting Diode) can help to prevent and control papules, pustules, and typical acne quite effectively if done properly. The L.E.D. penetrates into the dermis and slows sebaceous glands that create oils in the skin that can cause acne. Non inflamed acne such as whiteheads and blackheads tend to respond less effectively. Multiple treatments are required. Treatments are typically done twice a week for a few weeks. We offer L.E.D. treatments in office for $50 per treatment. A home regime would also be prescribed as needed. It is always best to have a consultation before treating any skin concerns.

LED Blue Light Treatment For Acne

LED blue light therapy is often quite effective for mild to moderate acne. Acne is often exacerbated by the presence of bacteria, particularly  P.acnes which multiply in the sebaceous glands. The skin becomes inflamed when the body tries to fight these invaders. Inflammation is something that is worth addressing/preventing since it can lead to acne scars.

People with acne typically have more bacteria in their follicles than those without acne. Keep in mind that this is just a correlation. Bacteria is not the cause of acne breakouts.

LED works when the light is absorbed by the polyphorins which are produced by the bacterial cell bodies. This leads to the destruction of these organisms.

The Spectra laser, however, not only addresses bacteria, it also inhibits the activity level of oil producing sebaceous glands. And it also clears out blockages in your skin pores.

Blue LED light can be helpful for acne, particuarly preceded by Levulan

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Blue LED light can be helpful for acne by reducing colonies of bacteria responsible for acne and by exerting anti-inflammatory effects on the skin. However, the clinical benefits of Blue LED light multiplies when it is preceded by application of Levulan of various duration as determined by an experienced board-certified dermatologist when it used as part of photodynamic therapy (PDT).
