The SMAS, or superficial muscular aponeurotic system, is a deep underlying sheath of connective tissue that lends the face its shape. As we age, the SMAS descends due to gravity and the weakening of this tissue. A well performed SMAS facelift will reposition the tissue up and back, causing a more sculpted and youthful jawline. The jowls will essentially disappear, although if you have very fatty jowls then liposuction may be recommended as well. In any case, the lower face will not appear heavier after an SMAS facelift, nor will the jowls “hang.” There are many facelift techniques that can be customized to individual patients, so I recommend having a consultation to find out what kind of facelift is best for you. I hope this helps.
