How Blue Light Therapy Works?

If you’re amongst those who have tried it all, ointments and medications, nasty zit popping etc etc LED Blue Light acne treatments is for you! Along with its high efficiency to provide good results it eliminates all hassles any traditional treatment.

Blue light therapy has a wavelength of between 405nm to 420nm and is predominately used for its anti-bacterial benefits and hence serves as a potent cure for acne.Blue light at wavelength of 415nm is absorbed by a molecule called Porphyrin.  Prionobacterium acnes; the bacterium responsible for causing acne contains large amounts of Porphyrin. When blue light is absorbed by this molecule it releases free radicals into the bacteium, eventually killing it!

If you are suffering from acne then you may know that there are various causes (hormones, genetics, diet, etc.) but it always forms because of a blockage in follicles, skin organs that produce hairs. The sebaceous glands are attached to these follicles produce sebum. Excess of sebum allows the Propionibacterium acnes bacteria to propagate and form papules, nodules and other inflammatory lesions.

By using blue light therapy regularly, you will be able to eliminate the bacteria and reduce the inflammation, and thus see your skin get clearer and look much better.

For better results, it is recommended that you combine blue light for acne and red light therapy. Since, red light is proven to renew skin cells and thus it can reduce scars and redness caused by the inflammation.  


Research says: Blue light, particularly in the wavelength range of 405–470 nm, has attracted increasing attention due to its intrinsic antimicrobial effect without the addition of exogenous photosensitizers. Blue light therapy is a clinically accepted approach for Propionibacterium acnes infections. (NCBI)

The American Acne Foundation also affirms the efficacy of ‘Blue light’ treatment to heal acne.

• Blue light is natural and not harmful to the skin and has no side effects unlike the ultraviolet rays. UV rays are not used in treating skin disorders anymore because it causes skin cancer.

• Once the acne in your skin is exposed to the blue light, it causes a certain mechanism to kill the bacteria that causes acne. After several treatments, it will eventually cause the skin to clear out. There would be instances when blue light treatment is done individually while other times it is treated together with a topical medication.

Are there any side effects ?

One of the best available acne treatments is by using blue light therapy. This therapy is often recommended by dermatologists when topical creams and other methods have failed.  The blue light laser treatment methods has also been approved by the US Food and Drug Administration (FDA).

According to reviews made by the American Academy of Dermatology, blue light laser acne treatments are quite effective, however the academy notes that the therapy only works best for surface acne, and not for acne cysts.

There are very minimal reported side effects of the laser acne treatments like dry skin, inflammation around the treated areas, and discoloration which are often mild and disappear after one to two days. Dry skin can be managed with a moisturizer. Though no reports have been made and hard to prove, there are experts say that prolong exposure to blue light laser acne treatment can cause cancer.


Does vitamin D deficiency cause acne?

Busting all your myths about it, the answer is NO. The cause for acne as we have discussed above, lies in infection by P.acnes bacterium. Too much of sebum (oil ) secretion aggravates the problem since this bacterium thrives on sebum. 

But is there any link between vitamin D and acne?  What science suggests is that vitamin D is known to boost the immune system by activating the T cells, fights inflammation and also regulates certain hormones. So what we find is that low levels of Vitamin D make you susceptible to infections and hormonal imbalance that might take place and will trigger acne. Moreover, Vitamin D also suppresses sebaceous glands activity which helps to reduce the amount of oil your skin secretes thus helping to curb acne.

The final verdict is that you must be keen, to get optimum levels of vitamin D. Get a vitamin dosage chart and find out the right amounts, for it will help you fight this problem, but it still cannot be said that it it is the root cause for the problem, though it is an aid to alleviate the problem!


The Best thing about this Therapy!

You don’t always need to depend on a professional. You can DO IT YOURSELF too. A therapy session is usually performed at the doctors office but an important thing to note is that patients can opt to have the treatment done at home, because a wide array of home-based therapy kits are easily available. 

A study published in the journal of clinical and aesthetic dermatology supports the claim of ‘self treatment’ with ‘blue light’ and says: ‘Self-applied blue light treatment was reported to be easy and safe to use.’ (NCBI)
