Blue Light Therapy


Blue Light Therapy

Narrow band blue light phototherapy is well known as a method of reducing jaundice in newborn babies. Now it is seen also as having a promising role in treating mild to moderate acne but from a medical and scientific viewpoint, blue light therapy remains an understudied, investigational acne treatment, ie – more research is required to demonstrate it has a proven safety track record and identify its long-term effects.

Blue light therapy involves directly exposing the entire skin area affected by acne to either a continuous or intense pulsed light which has been shown to have anti-bacterial and anti-inflammatory effects. A typical treatment requires two sessions per week over four to five weeks.

As with any therapy, there are risks involved. Unfortunately, there is only limited information about the short-term side effects and risks with even less known about blue light’s longer-term safety.

Short-term side effects

During treatment and in the weeks following therapy, some people will be affected briefly by:

  • Photosensitivity (sensitivity to light)

  • Worsening of acne (possibly more likely to occur in people with severe acne)

  • Skin pigment changes (uneven or blotchy increase in skin pigment)

  • Skin dryness

  • Redness and swelling of treated areas

Long-term side effects

Sunlight is known to have a number of harmful effects on the skin which can be delayed for years or decades after excessive exposure.Although there is no data on the long-term skin effects of repeated exposure to intense blue light, potential concerns include:

  • It may suppress the skin’s immune system.

  • It may cause photo-ageing of the skin.

  • It may contribute to skin cancer risk.
