Juls,
Thanks a lot for your professional input.
The reason I asked is that my beauty expert is evasive and unclear. I will be changing beauty parlors, because my skin is now breaking out in acnes. I think it has to do with the fact that my skin was badly irritated after my first session. She gave me a lot of new creams she sells - of course, she is promoting her own skin cream - and when I asked her the same questions I asked you, her answers are like: "Well, it can and it can not." When I persist, she becomes irritated.
She claims to be able to take out the lines under my eyes, which are not deep anyway but when I ask her about how many sessions I need, she says: "We´ll see", but tried to charge me for 8 sessions. This is not acceptable to me, so I´m calling her after my lunchbreak to cancel my next session.
Thanks again and I´ll certainly ask you about more info.
