Dynamic phototherapy (DPT) is a non-invasive treatment method.
This new therapeutic alternative is aimed at selective destruction by light of pathological cells which have accumulated a photosensitising substance.
The specific active ingredient is incorporated into a cream (Metvixia).
After application, the cream is selectively absorbed by diseased tissues, making the tissues sensitive to light.
Under the effect of illumination with red light, the cream becomes active and destroys abnormal cells in a targeted manner; these are then eliminated by the body within a few days. Healthy skin surrounding the lesion is not affected.
One or two treatment sessions are needed.
Mild pain, redness, scabs and oedema may occur in the following hours or days. These symptoms disappear spontaneously within a few days.
DPT gives excellent results if the indication is appropriate.
The current indications are actinic keratosis of the face and scalp, superficial baso-cellular carcinoma and Bowen’s disease.
Other indications are currently being assessed such as acne, cutaneous photo-rejuvenation, psoriasis…
