Until some time ago, some skin lesions such as basal cell carcinomas, flat warts, keratoses, and actinic lesions could only be treated surgically. Today, medical technology has made available a non-invasive therapy that is very targeted, well-tolerated, and highly effective.
Non-invasive action against certain diseases of the skin
Photodynamic therapy (PDT) consists of a particular LED light source with high intensity and with a specific wavelength that activates the action of a particular drug, 5-aminolevulinic acid (5-ALA), that, when applied to diseased skin, penetrates just the altered cells, selectively destroying them and eliminating their causes through a photochemical reaction and without harming the surrounding healthy skin.
5-ALA is applied on the lesion, then the affected area is exposed to the LED light, activating the drug. The time required for treatment is variable, but is generally around 20 minutes.
The result is seen within one month and, sometimes, a second treatment may be recommended.
The treatment is generally well tolerated. After exposure to the LED light, the skin is reddened and, for two or three days, should not be exposed to natural or artificial sources of radiation. In the days following treatment, you may notice the formation of a flaky scab which is to be medicated, and heals after one to two weeks at most.
This is for anyone who has pre-cancerous lesions on the skin, particularly on the face and scalp.
The elimination of precancerous lesions is essential to avoid the occurrence of more serious diseases. In addition, after the photodynamic therapy, the skin's general condition greatly improves.
