What is the correct pressure to apply when wearing the chin strap post chin, neck liposuction? I am on day 4 post neck, chin lipo and buccal fat removal. The surgeon told me the correct pressure is imperative, but I am unable to gauge what that might be. What is too tight? What is too loose? Am I actually wearing this thing to create the contour of the result? In that case it will be very important to position the straps a specific way. Thanks in advance for your feedback!
