Simulated daylight photodynamic therapy (SDL-PDT) using white light (MedisunR) is very efficient in treating multiple actinic keratosis on the face and scalp. This treatment is initially combined with a low intensity fractional CO2 laser. Then the MetvixR (methyl aminolevulinate) cream is applied, which, thanks to the micro perforations created by the CO2 laser, will penetrate the skin effectively. The skin is then exposed to white light for 1 hour at the surgery. This leads to the accumulation of protoporphyrin IX in the precancerous or cancerous cell, which causes its destruction.
In contrast to conventional PDT with red light, which is very painful, you will not feel any pain apart from a slight tingling. Consequently, this treatment does not require a local anaesthetic or the interruption of your anticoagulant treatment. Following this treatment, the skin will be red and peel for a week.
This technique can be carried out all year. Following treatment, a daily application of a high-protection sunscreen is absolutely necessary all year round.
Prior consultation with a dermatologist is compulsory. Together, you and your doctor will assess which treatment is best suited to your needs and what the possible side effects might be. Based on this discussion, the doctor will also provide a quote.
