LED Light Therapy

Blue light therapy is a pain-free non-invasive treatment which uses light to treat various skin conditions which are on or just beneath the skin. Blue light therapy can be done either at home or at a dermatologist office.

Blue light therapy is used to treat sun damage, acne and prevent skin cancer. It removes precancerous skin lesions and cancerous skin lesions which have not spread to other parts of the body or metastasized. It also reduces sebaceous hyperplasia or enlarged oil glands and improves the skin texture. It as well removes scars that were caused by acne.

How blue light therapy works

Blue light therapy is usually done as an outpatient procedure except if it done on a high risk basis such as treating skin cancer. Each session lasts about fifteen to thirty minutes depending on the severity of the condition being treated and the area.

When going for a treatment session it is advisable to go with a makeup free skin. Goggles to protect the eyes will be provided for the duration that the patient sits or lies under blue light. The procedure is pain free and there is no discomfort.

After the treatment there may be some redness and inflammation on the treated area but that fades quickly. The results of the treatment become visible between 2-4 weeks but they may show up earlier. Several treatment sessions are needed to get the optimal results. Unlike other photodynamic treatments you do not need to avoid the sun after the blue light therapy.

Skin infection happens to be the biggest risk in the case of post-treatment blisters which may occur and left untreated.
