Guide on the best blue light therapy for acne

Acne is commonly associated with the teen years, but breakouts can occur at any age. Acne during your adult years can be even more frustrating, because fewer of your friends and colleagues are suffering with you.

Keep reading to learn more about blue light skin treatment for acne, including how it works to fight breakouts and what kinds of at-home machines are available.

What is blue light therapy?

Blue light therapy is a groundbreaking technology that heals acne from the inside out by killing the bacteria that causes acne to form.

The devices reviewed below target propionibacterium acne (P. acne) – the bacterium responsible for up to 90% of acne cases. P. acne lives deep within the hair follicles, where it blocks the release of oil. This blockage causes blackheads and blemishes to form.

Blue light therapy is able to penetrate the skin to kill P. acne at the source.

Advantages of blue light therapy: it’s natural, painless, non-invasive, and (in most cases) won’t cause irritation. Treatment is simple and has shown to be very effective in treating hormonal acne. There is no down time after treatment

Disadvantages of blue light therapy: devices can be expensive, but are less expensive than professional treatments.

Blue light therapy doesn’t work for everyone, and is less effective when used to treat severe cases (including cystic acne).

Blue light therapy utilizes high-intensity light, so you shouldn’t treat areas near the eyes and you should always wear protective eyewear (most kits include protective goggles).

Blue light acne treatment side effects include light sensitivity, skin sensitivity, nausea, and headaches. These side effects are minimal compared to what you may experience from antibiotics or topical acne treatments.

Blue light therapy is only effective when used in cases where the acne is caused by bacteria. If your acne is caused by something else, blue light therapy will not work.

Pregnant woman and individuals younger than 13 should not use blue light therapy.

Silk'nSilk’n is a popular brand in skincare, offering many at-home devices for acne, anti-aging, and hair removal.

Expect to see results 6-8 weeks after completing the treatment course. Silk’n claims users do not need to wear protective goggles during treatment, but I would recommend doing so ayway.

BlueMD does not use harmful UV rays, but make sure to wear the goggles provided when you’re using it.

This model is on the expensive side, but it will save you hundreds compared to professional blue light treatments.

Of the three machines reviewed here, BlueMD is the best acne light therapy device overall.

Amazon customers gave BlueMD 3 out of 5 stars.

Note: The key with all of these devices is consistent use. Don’t expect to see results overnight.

Blue Light & Cystic Acne

Acne-minCystic acne can be difficult to treat because the bacteria involved multiply very fast.

At home devices like the ones described above have not been overly successful in treating cystic acne. Individuals with cystic acne are advised to visit a dermatologist before starting any sort of treatment.

A professional blue light treatment course for cystic acne typically involves 1-2 treatments per week for up to 8 weeks. The cost of a single treatment ranges from $40 to $200.

Side effects may include temporary dry and/or red skin. Using blue light to treat cystic acne is a relatively new idea, so it is possible there may be other side effects.
