What Is To Know About Cosmetic Laser Treatments (see pictures at the end of this text):
Each skin is unique and demands a different number of treatments. The doctor should evaluate the number of treatments which will be possibly needed in your case. Take treatments one by one and watch the result after each treatment. If there is no improvement after two treatments, you should probably consider stopping them altogether.
Achieving permanent hair removal or getting good results for cosmetic laser treatments is not a simple procedure. In case of hair removal, for example, it means that laser must destroy each hair root, otherwise hair will grow again. If you consider that each cm2 on man's chest may have up to 80 hair roots and on each cm2 of woman's face up to 300, you will understand the difficulties connected with such operations. Unless all hair roots are destroyed, the aesthetic result will be problematic. If hair roots are located deep in the skin, the laser operator has to work in very high energy range, sometimes up to 45-50 J which requires a perfect control of the laser.
Make sure you are treated by a physician who has a vast experience in laser cosmetic treatments and holds the Israeli license for medical practice. The physician who gives you treatments should assume full responsibility for your treatment and its results.
Please note: Laser treatments are safe and efficient only when they are performed by a licensed physician specializing in this domain. 
Therefore the use of laser for cosmetic treatments (unlike, for instance IPL), according to the regulations of the Ministry of Health, is reserved exclusively for physicians. 

Are there any Possible side effects?

Temporary Side Effects

After the treatment you may have temporary erythema (redness) or temporary per-follicular oedema (swelling/bumps).
Any initial reactions should settle down within a 48 hour period.
Aloe Vera Gel and cool/ice packs should be used to reduce irritation.

Rare Side Effects

The following side effects are very rare and can be avoided by following aftercare advice:
Hyper-pigmentation (darkening of the skin) and Hypo-pigmentation (Idiopathic guttate hypomelanosis, white spots) can be avoided by ensuring that you use sun protection cream (spf 50) and avoid sun exposure at least 6 weeks after the laser treatment.
Some people may experience skin crusting in the affected area. This is typically a 
minor issue but can be inconvenient. Crusting can sometimes lead to cause temporary scabbing. By taking care of the treated area after laser removal, such as by using sunscreen and avoid sun exposure, a person may prevent any lasting issues from this treatment. These expected conditions are known and recognised,
and will resolve themselves in a relatively short time.
