How Long Should You Use Red Light Therapy on Your Face?

When thinking about red light therapy, you should imagine it as an exercise for your cells. Similar to how you can use weightlifting for your muscles and cardio for a healthy heart and lungs.

Just as you wouldn’t expect immediate changes to your physique after going to the gym a few times, you can’t expect red light therapy to take effect after using it once or twice. Hence, you may utilize RLT for 20 to 30 minutes twice or thrice a week.

However, individuals respond to exercise differently; the same goes for red light therapy. So, changes come if you stick with them and persevere, and it’s important not to give up until that point. Even though waiting weeks to see results can be frustrating, patience is the key.

The skin light sensitivity

Red light has been proven to be completely safe to use on the facial region multiple times. Though skin color, tone, and thickness affect how your skin will react to absorbing the red light photons.

People react differently every time, so two people cannot get the same results in the same amount of time. Because of this, it might also be smart to consult a medical professional about how sensitive your skin might be to this type of therapy and how it would react.

Altogether, your body ailment, overall health, and skin type are all factors you need to consider to determine how long you can use light therapy on your face.

Session duration

Participants in one of many studies utilized red light twice a week. It was found that after 30 sessions, the skin issues on their faces showed significant improvements.

After that, less frequent sessions might help maintain skin improvements and provide fantastic anti-aging effects.

Sessions should last somewhere between 10 and 15 minutes each; exceeding that period is not recommended.

Finding the optimal dosing

It’s generally recommended that you experiment with a particular duration and intensity of red light to find the right dosing.

Light intensity, also known as irradiance, is defined by how far the light source is from you. For example, administering treatments for skin conditions around 12″ to 18″ is ideal. But for face treatments, you should keep it at a distance of about 18″ to 24″. 

So, when trying to find the right intensity for your treatments, ensure it’s in the margins of that distance. Ensure yourself while wearing some eye protection for light therapy.
