Laser treatment at spa.

i'm a 21 year old girl and my complexion is quite fair unfortunately i have some acne scars.I have tried several expensive creams and even natural remedies but still no effect.I have been to a beautician who told me that i have to do a laser treatment which is included in the facial.I did the laser treatment twice for acne treatment and i have to go for a thrice time as well for the scar treatment.I notice a great improvement but is it really helpful or it can cause damage to my skin later.
