I've always had a square jaw treatment once every 5 months, and
I didn't think it had much of an effect, but
there was a time when I didn't get it for a year
and it became completely square.
I think I felt the effect of Botox for my square jaw at that time.
So, I've been getting it regularly since then.
I heard that contouring injections need to be administered at least three times to be effective,
but for financial reasons, I only had one injection and
it didn't really work.
Later, I looked into contouring injections and found out that they also had side effects, so
I haven't had them since.
