So as long as you follow and keep to the schedule that the professionals created especially for you, there is no need to be afraid that you might be overdoing the red light therapy.

How Much Time Until You See Results

Seeing results for the first time is different for every individual. As we all have different ways of functioning, genes, and physiology, there is not one universal time after which every person sees the results.

In our experience, people usually see their first results between four and eight months. If you do therapy once or twice a month, you may see the results after four to six sessions. 

The best thing you can do is not over-obsess and check for results every day because even if there is some difference, you will not be able to notice it. Instead, you can check for results and take pictures every seven to ten days. Only this way will you be able to see whether there are some changes.

What Factors Influence the Perfect Red Light Therapy Dosage?

Although numerous factors can determine the correct dose of red light for every person individually, these four factors have the strongest influence on determining the dosage.

Therefore, before starting the red light therapy, the professionals will discuss with you the three most important things:

Your overall health 

You must disclose any health issues, illnesses, physical and mental health conditions, worries, etc. It is best if you do not hide anything, as that can slow down the entire process and might cause some unwanted complications.

Your skin’s light reactivity and sensitivity 

As this therapy is strictly through a red light, the professionals must see whether your skin will tolerate the red light and whether there will be any adverse reaction.

The condition(s) you want to treat 

In order to help you, the professionals will need to know what conditions you want them to treat so they can determine the frequency and duration of the red light therapy sessions.

The goals you want to achieve 

By discussing what goals you want to achieve and what your expectations are after the red light therapy ends, the professionals will be able to give you an answer on what you can expect and how much your condition can improve. That way, you won’t have false and big expectations if they can not treat the condition entirely with red light therapy.
