Blue Light Treatment for Acne: Safe & Effective ?

Blue light therapyFor centuries, people who had acne were told that they needed the sun to “dry out” their skin. While both dryness and sun are enemies of healthy skin, it turns out the old advice to expose acne to the light of day was partially correct. Visible blue light, it turns out, can kill acne.


*Visible blue light kills acne bacteria.
*Three blue light treatments kill about 99.99% of acne bacteria that the light reaches, although some acne bacteria live deep in pores.
*Red light therapy can help shrink the sebaceous glands that produce the oil that clogs pores.
*Light treatment alone, however, only treats blemishes and pimples after the fact.
*A complete acne care system is always needed in addition to blue light treatment of acne. Blue light treatment helps you get control over acne, but a complete acne care system helps you keep control over acne.

How Killing Bacteria Heals Acne

Before getting into how blue light kills acne bacteria, it is helpful to review how killing acne bacteria cures acne. Many people suppose that if they just kill acne bacteria, all their acne problems are over. The fact is, bacterial infection is just part of the problem of acne.

Skin pores sit on top of oil-producing sebaceous glands. The sebum produced by these glands keeps the skin flexible, and also helps transport dead skin cells from the bottom and the lining of the pore up to the surface of the skin where they can be rinsed away.

Sometimes dead skin cells clump together and clog the pore. Or inflammation of the skin triggers production of excessive amounts of skin oil. When this happens, acne bacteria can be locked inside. The bacteria attempt to “break out” so they can move on to another pore first by consuming excess sebum. They break down skin oils into essential fatty acids that are beneficial to them but harmful to the bacteria. This can keep them in check. But if the problem is the pore is clogged with dead skin, then the bacteria have another way out.

Bacteria release chemicals sensitizing surrounding skin cells to inflammatory chemicals released by the human immune system. The immune system releases histamine and interleukin-8 to attack the bacteria, but winds up attacking the skin. A pimple pops up and provides the bacteria an escape route. Many bacteria are killed by the immune system, but many survive to colonize another pore.

Killing bacteria stops them from making skin sensitive to inflammation. But just killing bacteria does nothing to stop production of excess skin oil or to repair the skin. Killing bacteria is always just part of acne skin care. It’s also necessary to follow a skin care routine to keep the skin in balance.

How Blue Light Kills Acne Bacteria

Blue light treatmentAcne bacteria are killed by visible blue light, that is, light you can see, not UV light, of wavelengths between 407 and 420 nanometers. The bacteria have pigments in their protective cell membranes that resonate at those frequencies. These pigments break down the membrane, eventually killing the bacterium.

On a Petri dish, three exposures to blue light kill about 99.99% of acne bacteria. In the skin, the kill rate is not as high. That is because blue light cannot reach very far into the skin, and acne in deep pores or in cysts beneath skin are unaffected. Even so, many people who use blue light report noticeable results in as little as a day, because killing bacteria stops inflammation—the immune system stops producing inflammatory chemicals to kill bacteria because the bacteria are already dead.

Red Light Relieves Inflammation

Blue light has an immediate effect on pimples, and a longer-term effect on whiteheads and blackheads. Blue light can keep whiteheads and blackheads from getting worse, although they have to be removed from the skin by other means.

The addition of red light to skin treatment, however, treats deeper pores. Red light can travel further into the skin than blue light. It can also generate heat at the level of the sebaceous glands. If red light is not used in excess, it can shrink the glands and reduce sebum production. If so much red light is used that the skin burns, however, the effect is the opposite greater sebum production.

Using Light to Treat Acne

The best way to use light to treat acne is to use a combination of blue light and red light, but making sure the light is not so intense that the skin burns. It is even better to treat the skin with intense pulsed light, short bursts of multicolored light that can heat and shrink the sebum-producing pores.

Blue light for acneA red and/or blue home light treatment lamp is not going to cause any kind of damage to the skin if it is used as directed. People who assume that if a little light cures acne slowly a lot of light must cure it fast usually suffer serious problems from light therapy.

Intense pulse light, however, is riskier. Since it heats glands that lie deeper in the skin, it can cause burns and swelling unless it is used exactly as directed. Never, ever give yourself longer or “extra” light treatments beyond the recommendations of the makers of your lamp.

What You Need to Do In Addition To Light Therapy to Achieve Blemish-Free Skin

Blue light therapy can kill acne bacteria in your pores, and red light therapy can shrink sebaceous glands beneath your pores, but you can’t achieve lastingly blemish-free skin without careful attention to cleansing, moisture, and exfoliation.

It is essential to use the right cleansers in the right way to keep oil from accumulating on your skin. Harsh detergent cleansers, however, can actually increase the production of oil in your skin.

It is essential to keep skin moist to keep it flexible so pores stay open. Even oily skin can dry out, especially around the eyes. You will also maintain a healthier skin color if you keep your skin moist.

Oil and bacteria are not the only things that can block your pores. Flakes of dead skin can tighten your skin and keep pores from emptying, too. Exfoliation can help keep your skin loose and free of fine lines and wrinkles as well as blemishes, but you have to use the right product for your skin, at the right concentration and at the right pH.


Now there is effective acne treatment without costly acne medications. Discover the benefits of blue light therapy…

“Blue light treatment is a major breakthrough and could be an excellent alternative for those patients who have had minimal success with traditional therapies…” — Dr. Arielle N.B. Kauvar

What is Blue Light Acne Treatment ?

Blue light acne treatment uses blue light (405nm-470nm) to kill acne bacteria on and under the skin instead of topical or oral medications. Throughout the treatment, the skin is exposed to a blue light source for a short period of time ranging from only a few seconds up to 15 minutes depending on the product. In-home treatments are recommended daily until acne is either cleared or under control, then the frequency is reduced to maintenance treatments twice to three times per week. Blue light is an effective acne treatment, but it’s not a cure, so consistent treatments will be necessary to keep acne under control.
How Does Blue Light Acne Treatment Work?

Blue light kills acne bacteria. How?

Blue light acne treatmentWhen blue light strikes acne bacteria cells it sets off a chemical reaction that causes the bacteria to self-destruct. No harm is done to any other cells on or in the skin. Here is a more scientific explanation from the AAD:

« Blue Light gets at the core of what causes acne eruptions: P. acnes, the bacterial responsible for causing acne inflammation, pumps out tiny molecules called porphyrins. When those porphyrin are exposed to certain wavelengths of light, they produce free radicals that kill the bacteria. Without P. acnes around to cause inflammation, acne clears up. » American Academy of Dermatology 2002

Research Leading to FDA Approval for Blue Light Acne Treatment

Almost every blue light acne treatment on the market today bases its marketing on this study, done at the Imperial College of London, and published in the British Journal of Dermatology in 2000. Here are the highlights:

• 107 patients with mild-moderate inflammatory acne (acne vulgaris) participated in the trial.
• The blue light peaked at 415nm, the red light peaked at 660nm (What does this mean?)
• Patients used the lights in-home for 15 minutes daily
• There was a 76% drop in visible acne over 12 weeks
• Combination Red and Blue light therapy was ‘significantly superior’ to blue light alone or benzoyl peroxide.
• Blue & Red light improve acne by combining anti-bacterial and anti-inflamffatory action.
• Red & Blue light phototherapy is a safe and effective treatment for acne vulgaris.

Based on this research and similar studies (detailed below), the first blue light acne treatment « system », ClearLight, gained FDA approval in 2002.

Since then, many smaller studies have been done all over the world, all confirming the effectiveness and safety of blue and blue & red light acne treatment. A few are listed at the bottom of this page for your continued research.

Red Light Speeds Acne Clearing and Helps Prevent New Scars

Visible red light (630nm-700nm) therapy is an effective, scientifically and clinically proven acne treatment that speeds the skin’s natural healing process and efficiently prevents scarring. David Olszewski, EE, IE, and co-author of Light Years Ahead: The Illustrated Guide to Full Spectrum and Colored Light in Mindbody Healing discovered that there is a 200 percent increase in the speed at which skin heals when it is exposed to visible red light.

In fact, in 1903, Niels Finsen won the Nobel Prize in Physiology for his use of red light in small pox treatment for the acceleration of healing and the prevention of scarring. Finsen also used the same red light techniques to treat lupus patients, successfully aiding in the treatment of this often disfiguring disease.

How Does Red Light Work in Acne Treatment?

When different wavelengths (colors) of light shine on the skin, they are absorbed into the skin, setting off natural processes within the body. This is called often called photobiostimulation.

Visible red LED light is capable of penetrating the skin to a depth of about 8 to 10 mm. Once absorbed, the light provides adequate energy to stimulate the body’s natural healing processes. This makes visible red light therapy an ideal acne treatment, as it decreases inflammation, speeds acne clearing, and reduces scarring – exactly what acne sufferers are looking for.

If you would like to get the most out of your light therapy for acne, combine both blue and red light for the best possible result in the least amount of time.


How to Use Blue Light Therapy to Clear Up Your Acne

Blue light acneBlue light therapy for acne can reduce up to 60 percent (!!) of your acne. That’s a fact that has already been scientifically proven. If you combine blue light therapy with traditional treatments, such as prescription creams and antibiotics, you can keep your acne completely under control. The best thing about it is that it’s a natural treatment that basically kills Propionibacterium acnes (P. acnes), the bacterium that causes acne inflammation. It’s also completely painless.

New technology devices combine blue light with red light – Which If you combine the blue lights that kill bacteria with red lights, which help reduce inflammation and improve healing.

These therapies can also improve skin texture and lessen the appearance of scars, so they may be good treatment choices for people with both active acne and acne scars.

How Does Blue Light Therapy Work and is it Proven Scientifically?

To put it simply, it has been proven that blue light therapy for acne – in the 405nm-420nm spectrum – actually kills Propionibacterium Acnes(P. acnes) bacteria. P. acnes bacteria create tiny molecules called porphryins. When porphyrins are exposed to blue light they produce free radicals that kill the bacteria that cause inflammatory acne. It sounds quite complex, but it’s a wonderfully simple solution.

In 2000 an independent research study performed by the Imperial College of Science Technology and Medicine at Hammersmith Hospital in London determined “We have found that photo therapy with mixed blue-red light, probably by combining antibacterial and anti-inflammatory actions, is an effective means of treating acne vulgaris of mid to moderate severity, with no significant short-term adverse effects”. (Data from

Remember: P. acnes multiply very fast, so ongoing treatment is necessary for best results.

Blue Light Therapy for Acne – Tabletop Device or Handheld Device?

Blue light therapy for acneTabletop light therapy devices usually require 10-15 minutes of treatment once a day and you have to sit very close to the device. Handheld devices require you to hold the device directly on the acne areas for at least 30 minutes – twice a day. Obviously hand held devices are cheaper than the Tabletop devices and it really depends on how much time and patience you have for your self treatment.

Side Effects and One Important Warning

Possible side effects of blue light therapy include temporary redness and dryness in the treated areas, but these are only temporary. The level of UV light in these devices is also very low and appears to be well within the range of safety.

Warning: One type of acne that does not respond well to blue light therapy, and which may actually worsen as a result of treatment is called nodulocystic acne. Don’t use this therapy if you have this kind of acne.
