A MACS facelift is one of a continuum of face lifting technique styles which have progressed over the last 50 years. There are 3 basic layers of tissues to be "lifted" in the face:the skinthe SMAS (a fascial corsette underlying the skin which keeps the tissues tight and together)the soft tissues including muscles, fat, nerves and blood vessels. Most facelift techniques use the first 2 layers to perform the lifit.the skin is most recently redraped in a superolateral (upward and outward) rather than backward direction and the excess is trimmed.the SMAS is pulled and tightened in a superior (upward) direction and the excess trimmed or doubled over to add more volume.the soft tissues maybe volumized to fill, soften and change the contours and folds of the face. For example, fat or filler maybe used in the cheeks, temples or nasolabial and marrionette folds. During the initial healing process, swelling and pulling of the skin or deeper tissues can cause this wave form you present in your photo (thanks for sharing it with us). Other considerations are redraping the skin or pulling the SMAS in a backward direction. My suspicion is that the tissue tightness will relax during the next few weeks as the swelling diminishes. In approximately 3 months with some appropriate massage, you will observe a more natural appearance.It is best that you return to your surgeon and review with him / her your concerns so he / she may instruct you as to what to do and provide his / her experience in managing this issue. I hope this was helpful. I wish you the best!
