Light itself is 100% painless. Photomodulation is simply streaming photons at you, no different than standing near a light bulb.

You may experience a warm sensation on the order of 2 to 4 degrees Celsius during the session from the SLEDs. After treatment, you should reduce direct exposure to the sun as much as possible.

Who shouldn't use this therapy? Some contradictions are: connective tissue damage, autoimmune disorders, pregnancy, use of light sensitive medication, Accutane, ALA or retinol-based cosmetics.

Please discuss this with your practitioner.
