What Are the Common Side Effects of Red Light Therapy?

While red light therapy is typically safe, a small number of users may experience mild and temporary side effects. These effects are usually related to sensitivity to light or extended treatment sessions.

Commonly reported side effects include:

• Mild skin redness

• Temporary warmth in the treated area

• Slight skin dryness

• Temporary eye discomfort if protection is not used

These reactions generally occur when sessions last longer than recommended or when devices are placed too close to the skin.

Reducing session duration or increasing the distance from the device often resolves these issues.

Most people tolerate the therapy very well and experience no significant side effects.
