I had horrible 11 lines for as long as I can remember. Botox always scared me from all the 'horror stories' i have heard. However, I became very self conscious of the lines to the point where I decided to go ahead and do it.
My dermotologist told me of the side effects, droopy eyelid, horrible headaches, etc. However, she said that she used about half of what most places use because with botox the lesser the better.
The pain was just a little pinprick, and there was no topical pain. I did have a headache for about a week, but other than that, I have been very pleased,
