How Does Blue Light Therapy Work?

Almost everybody experiences acne breakouts at some point in their life, some more severe than others. This inflammatory issue is brought on by the build-up of bacteria on the skin that can cause inflammation, discomfort, and unsightly blemishes. To heal and get rid of acne, one must first kill this bacteria. Blue lights are able to kill the bacteria naturally, in a way that is safe for your skin. The process is safe and easy and requires no chemicals or ointments to be applied to the skin before treatment.

In some cases, patients can receive blue light therapy at their doctor or dermatologist’s office. The way it works is that your doctor will either sit you in a blue-lit room or place a blue light mask on your face or other affected areas of the skin. It’s as easy as that and has no recovery time. The blue antibacterial light waves are able to penetrate the skin and begin killing off bacteria immediately. This process can also be done to treat staph infections and oral gum disorders.

Today, several products are available that allow you to perform your own blue light therapy at home. The most popular products are blue light masks, and wearing one for a short amount of time during your normal skin-care routine can keep your face clean and free from acne. Another popular home product is a blue-light mouthpiece. These can be worn on the teeth for a brighter smile and to combat gum disease-causing bacteria.

Cons of Blue Light Therapy

It is normal to have concerns with any type of cosmetic or medical practice. There are very few risks involved with blue light therapy, but be aware of the following:

  • Eye protection must be used during therapy, because prolonged exposure to the lights may damage your vision over time.
  • People with drug-resistant non-seasonal depression should not use phototherapy, as it can induce mania. Furthermore, studies have shown that blue light therapy is not effective in treating non-seasonal depression.
  • Some individuals report temporary headaches and eye strain. Nonetheless, these symptoms are not an indication of a permanent injury.
  • There may be a flare of acne. However, it is only transitory.
  • Allergic reactions (e.g. hives or eczema) may appear.

Tips on How to Use Blue Light Therapy

Follow these simple steps to begin curing your acne at home with blue light therapy:

  • Make sure that your face has been thoroughly cleaned and patted dry before you begin therapy. This allows for the light to easier penetrate your skin without anything else, like dirt or oils, getting in the way.
  • Put on the protective eye-wear provided with your light therapy mask. If one is not included, bu sure not to turn the light on until the mask is fully in position.
  • Place the mask on your face, paying special attention to proper placement around eyes.
  • Once the mask is properly placed, you can go ahead and turn on the blue lights.
  • Wait the recommended time for your specific mask. In most cases, this will be about 10-15 minutes.
  • That’s it! Remove the mask and carry on with your day.

Making Blue Light Therapy More Efficient

The effects of this therapy are best maintained through consistent treatments. Because the process is so safe and simple, you can work it into your skin-care routine every day or night. This ensures that no acne-causing bacteria has a chance to build-up and keeps your skin looking clear and fresh at all times.

As we noted above, this therapy is much more effective when done on a freshly washed and dried face. Dirt and oil sit on top of your skin and can actually block the blue light waves from properly penetrating your skin’s surface.

Precautions to Remember Before Trying Blue Light Therapy

This process is usually safe and risk-free. The only precaution that you need to take before trying this therapy for the first time is to wear protective eye-wear. Be sure to never stare into the light source, as this may damage your vision over time.

Blue light therapy is becoming increasingly popular as a cosmetic practice, especially for inflammation and acne. It is incredibly effective and has less associated risks or side-effects than any almost any other acne treatment. All of the benefits of this therapy far outweigh the one possible drawback, which is eye irritation or damage. It’s a great option for anyone who wants to move away from harsh chemicals in their skin-care routines, or for busy individuals who need something fast and simple to work into their hectic schedules.

You can purchase a light therapy mask for home use and follow the steps described above. Nonetheless, to prevent certain risks, we recommend scheduling an appointment with a specialist. Try blue light therapy under the supervision of a dermatologist to start seeing the results that everyone is raving about.
