I paid for one session with a mix of worry and sincerity, thinking, well, there are no side effects anyway, so let's just get it done during a sale and let go of any lingering attachment. Since then, I've ended up paying for a total of three sessions bit by bit... At that point I thought I should have just signed up for a program instead... I live far away in the provinces, but I have already paid and left it on hold.
Honestly, it wasn't like my face looked dramatically huge and then became tiny as a button or anything (I have thick skin and round cheeks with plenty of fullness in the cheek area...)
