Does Acne Light Therapy Work?

Sunlight or UV light has long been known to improve acne by killing bacteria in the skin. This has lead to the development to many acne light therapy devices, but do they really work and are they worth the money?

Blue Light Treatments

As many as one in 20 adults have persistent acne, which can prove stubbornly resistant to both over-the-counter creams and washes, and antibiotics.

If you are one of the many people who have tried some of the best selling acne treatments like Clear Skin Max or The Murad Acne Complex Kit but seen little or no improvement then acne light therapy might be the answer.

What is Acne Light Therapy?

Sunlight or UV light has long been known to improve acne. The reasons for this are not fully understood but it is thought to be due to antibacterial and other effects of the ultraviolet spectrum. Some of the visible violet light in sunlight activates a porphyrin (Coproporphyrin III) in Propionibacterium acnes which damages and ultimately kills the bacteria by releasing singlet oxygen.

Obviuously long term exposure to UV light to treat acne is likely to cause skin damage or even skin cancer so acne light treatments have been developed using the blue and red light wavelengths.

Are there and side-effects of light therapy?

At-home light therapy machines usually have very few or no side effects. In some cases, the treatmentcan cause slight irritation or redness but normally only in very sensitive individuals. The level of UV light in these devices is very low and appears to be well within the range of safety.

Do Acne Light Treatments Work?

Since the first acne light therapy product for home use were developed in 2000, several studies have taken place. Study results have ranged from “statistically insignificant” clearance all the way up to 81% clearance of acne.

Most studies suggest that and overall improvements of on average 76% for 80% of patients occurs over three months. In addition to this, most studies show that blue-red light performs better than benzoyl peroxide and the treatment is far better tolerated. However it’s also worth pointing out that approximately 10% of users experienced no improvement in their acne but as with most products, they can not be expected to work for everyone.
