Blue light therapy is another name for photodynamic therapy. With this treatment, dermatologists have been able to successfully prevent actinic keratosis.
Actinic keratosis is a scaly bump that can range in size from a pinhead to an inch. It typically shows up on the face, head, forearms, ears, back of the hands, and lips when the body has been exposed to the sun. Approximately 10% of these lesions will eventually develop into the squamous cell carcinoma of skin if they are not treated.
This has the potential to decrease the amount of full-fledged skin cancers through photo-rejuvenation. This therapy is also able to treat large areas of skin with minimal discomfort and provides advantages over the other available treatment methods. The majority of people are candidates for this type of therapy including those with diabetes.
It is partially preventative and proactive. The people with the highest risks for developing actinic keratosis spend a great deal of time outside and do not wear protective clothing or sunscreen. The most vulnerable are farmers, individuals with red or blond hair, fair skin and green, gray or blue eyes. Even if the person has a darker complexion, an excess of sun exposure can put them at risk.
How does this treatment work?
The treatment begins when the photosensitizing liquid is applied to the area of the patient’s skin that is affected. The individual remains in a dark room for approximately sixty minutes to enable the liquid to absorb. The affected area then receives seventeen minutes of blue light. During this treatment, the individual must wear protective eye goggles.
It requires around seven days for the treated lesions to heal. There is often sensitivity to the sun during this period. It is extremely important for the person to wear protective clothing and use sunscreen for the first 24 to 48 hours.
