Significance of Light-Based Therapy in Acne Treatments

Significance of Light-Based
Posted date on Sep 25, 2019

Acne is a distressing problem and sometimes so stubborn that no medications or treatments seem to work. Nowadays, LED has become the latest and most advanced treatment option to clear away the skin imperfection with minimal downtime. It is a medical treatment that involves the exposure of light of particular wavelength over the skin through a light-emitting diode. For acne, blue light phototherapy is used to kill the bacteria, Propionibacterium acnes or P acnes. This therapy is FDA-approved and has no side-effects. It is highly beneficial for people who suffer from mild to moderate acne.

How does blue light work for treating acne?

The excessive production of sebum results in clogged pores which obstructs the hair follicles thus form a microcomedo. The accumulation of cellular debris, lipids, and other environmental pollutants lead to colonization of P. acnes that leads to an inflammatory response resulting in acne formation. With the blue light treatment, the bacterium causing acne absorbs the blue light and gets destroyed by a free radical mechanism. This therapy also tends to shrink down the oil glands in the skin, which makes a person less prone to acne. The number of sessions required for clearing up acne depends upon the severity of acne and area of treatment.


The patient’s face is cleansed thoroughly with a gentle cleanser, and all the dirt or makeup is removed. The doctor will provide goggles to the patient to protect the eyes while the patient sits under blue light. The patient does not face any pain or discomfort while undergoing treatment. After treatment, some inflammation or redness may become noticeable over the treated area, which subsides quickly. The treatment requires no downtime, and the patient can apply makeup directly after the procedure. One should avoid touching or picking the blemishes on their skin between the treatments. One should follow the advice of dermatologist regarding the use of products and home care techniques during and after the treatment. The follow-up sessions are required to maintain results. The results are noticeable between 2-4 weeks or even sooner.

Benefits of Light-Based Therapy

  • Safe and gentle: Since only light at a particular frequency is used over a properly cleansed skin, the non-invasive treatment is completely safe and gentle over the skin. People with very sensitive skin types may experience redness, dryness, and swelling which tend to resolve on its own.
  • Painless: The patient does not feel any pain or discomfort. The patient has only to lie down and let the skin be exposed to the blue light. One can immediately resume their daily activities after treatment.
  • Drug-free: Many clinical studies have proven the efficacy of blue light to be 30-40% more than topical antibiotics. Thus, the treatment superficially eliminates the cause of acne and gives better results.
  • Appropriate for all body parts: This treatment can be performed not only over the face but also on the back, arms, chest, etc. where sebaceous glands are overactive.

Combined Red-Blue Light Therapy

The combined light therapy is very effective for improving the skin. The red light stimulates collagen and the blue lights kill bacteria. This helps to remove blackheads, pustular lesions and also improves the skin texture simultaneously.
