Those recommendations have been written by the dermatologists of the « Laser » group, Department of the dermatology French society.
The aim of the laser treatment is to cause the destruction of the “abnormal” blood vessels making up the angioma by using a thermal effect (burning). It is a long cure, which need several treatments, within three months between each session per zone. It is not possible to predict the amount of treatments necessary (it can be more than 10). The angioma is progressively getting lighter but rarely disappears completely, especially if the angioma is thick.
The pain

The uninterrupted laser spots are painful, you can need a local anesthesia. You can use an anesthetic cream (EMLA ®) under an occlusive bandage during two hours before the session or get a local anesthesia by injection, you will experience a feeling of burning for few seconds. To treat the eyelid zone, using protective shell on the eye is mandatory. They will be applied after an anesthesia of the cornea by an anesthetic collyrium.
After the treatment
The treated zone will be whitish with redness on the periphery. During 2 to 3 days, a swelling can be noticed, especially on the zone near to the eyes and when you used a local anesthesia by infection. After few days, dry skin and small thin scabs replace the whitish marks. They will spontaneously disappear in few days, and you shall not pull them off.  Some phlyctenes (blisters or bubbles) can be noticed.
During 4 to 5 days, you will have to pulverize thermal water and clamming cream. You can use some make-up to cover and keep a normal social life. A sun protection using suncream is mandatory after the treatment.
On long term, a risk of having some consequences is really low. This risk is increasing after getting several sessions on the same zone:
  • Hypopigmentation: skin more whitish than normal. Those white marks reduce spontaneously with time.
  •  Hyperpigmentation: darker marks, which will disappear in few months. This phenomena is more common for darker skin and with sun exposure.
  • Other kind of scars have been noticed (atrophic, hypertrophic) but they are pretty rare with the new technologies.
