I have suffered from acne so i had a lot of dark spots on my skin. I was very afraid of lsers touching my face but I was assured it would be fine b/c they woul put gel on my face before they zapped my spoys. I saw minimal results after the first application. However afte three treatment they were almost completly gone. Each treament cost me 75 dollars for less than 10 minutes of owrk but I think it was worth it. I no longer have to wear makeup to cover anything up.
