The only "con" I could foresee regarding this procedure is the possible risk of people suspecting you had work done because the results are in fact immediate. No one noticed that I had had anything done...because I had choppy bangs at the time so if you want to disguise your work for a couple of days I would recommend getting some bangs.
I have relatively wrinkle-free skin but wanted to simply prevent the deep furrow that plagues the foreheads of the women in my family. I e-mailed Dr. Palmer's office, got an appointment within a couple of days and was in and out within thirty minutes. It was literally less painful than a quickly plucking a few stray eyebrow hairs and the results are immediate. I am a regular now.
