Cutaneous Ageing Signs
Facial cutaneous skin ageing is defined by wrinkles, pigmentary disorders, telangectasia, the appearance of increasing unwanted hair, dryness, atrophy..
Non invasive intense pulsed light efficiently act upon the two major components of heliodermic ageing (= cutaneous ageing signs caused by sun): exposure): telangectasia (vessels) and lentigos (ageing marks).
Besides, laser treatment results in a better and nicer skin colour, skin tightening, skin smoothing.
The treatment may even lead to indirect signs of collagenic stimulation which improve skin tone and partially remove fine lines. For the last 10 years, vascular or pigmented disorders photorejuvenation have been treated with pulsed lights.
Pulsed lights may also be used to remove hair, although laser hair removal are more efficient in that case.
These lights produce very short duration pulses, (a few miliseconds) and very high luminous intensity (4000W/cm²), within the spectrum of visible lignt and infra red radiations (550 to 950 nm).
A cold gel is being applied on the skin area to be treated. The patient is wearing black protection googles through which he/she cannot see. The smooth handpiece glass surface is being laid down on the skin and emits pulsed light. The patient feels some light tickling, similar to the effect of a snapping elastic. Anesthesic creams are sometimes used but seldom necessary. Each session lasts about 20 minutes.
Protocole treatment generally consists in a serie of 4 to 5 sessions separated from 2 to 6 weeks between each other. Regular meetings are being scheduled. Fluencies are being progressively increased along the sessions in function of skin tolerance and efficiency. The objective is to obtain light erythyma and greyish pigmentary lesions. If the patient accepts to be a little bit more « marked », the amount of sessions may be diminished.
Transitory more marked lesions are necessary to obtain a positive result. The laser treatment makes pigments ascend, which accentuates the lesions, making the marks darker and causing micro scabs. It makes vascular elements more visible (possible aspect of purpura) and sometimes causes a peri ocular oedema. The patient can go back to work with covering make up. After 8 days, almost all treatment signs disappear.
- skin telangiectasia and lentigos
- hand lentigos
- coli erythrosis (red “décolleté”)
- Riehl melanose(red and pigmented neck, sometimes with the aspect of “dirty skin”)
