Laser treatment sessions do not strictly require any preparation beforehand. Some dermatologists nevertheless recommend that you protect yourself with a sun cream in the two weeks preceding the procedure in order to put the cells which make melanin to rest and to
avoid any post-procedural hyperpigmentation.
What happens during sessions
Sessions last from a few minutes to one hour, depending to the area to be treated. Local anaesthetic or sometimes general, is given depending on the type of laser. This treatment can sometimes be painful.
After a laser session
Treatments with a conventional CO2 laser are particularly affecting, which is why they are used less and less. Not only do they do they require treatment with general anaesthetic, but they mean taking a few days off work. Recovering whole face takes at least two weeks and redness can persist from 2 to 3 months. Sun exposure is forbidden for almost six months.
With fractional CO2 lasers, isolation is advised for 5 to 7 days afterwards. The dermatologist or aesthetic physician will recommend the application of a repairing cream that is:
- rich at first, to eliminate the scabs that can sometimes appear (depending on the type of laser chosen)
- lighter after scabs have disappeared and for the time that the redness last.
For other fractional and light pulse lasers, it is not necessary to isolate oneself because only the redness will persist. That can be soother by a healing cream with a light texture, recommended by the dermatologist or aesthetic doctor.
Finally, with regard to the treatment of rosacea and other imperfections, the aesthetic practitioner can also recommend a healing cream to be applied for 2 to 3 days, to soothe the skin and reduce inflammation and redness.
It is essential to follow the advice of your dermatologist or aesthetic physician when following through these steps.
