At first, I was scared of doing this or that, so I only got Botox once, but it really didn't have any effect. ^-^ During the consultation, I was told that my face would be more effective in contouring the face than Botox, so I got it together, but I had to be greedy, and it hurt a little, but it was bearable, and it was as cheap as this and highly satisfying. I don’t think there is one. Tightening? I also got an injection once, but it was the most painful so I won't get it again, but it seemed to have the best effect.
