It's not uncommon for our injectors to refer to the "triangle of youth" if you have been in our clinic previously. The shape of our faces in our youth is much like an upside-down triangle, with a majority of volume in the cheeks and a slimming effect on the lower face. During aging, this triangle flips. The face may appear "saggy" or "hollow" when bone density is lost, fat pads are reduced, and collagen production is slowed. To reverse the triangle of youth, we can use facial fillers to rebuild the foundation and add volume again. Full-face rejuvenation or "liquid facelift" procedures often involve injecting filler in areas such as the temples, cheeks, under eyes, lips, and chin. Full-face rejuvenation is an excellent option for patients who are looking for a non-invasive way to tighten sagging skin and add volume and contour. An injectable, dermal filler (we use hyaluronic acid fillers at our practice) and neuromodulator are combined in a targeted manner to restore volume to the face, smooth out wrinkles, and lift as well as sculpt the face during this non-surgical facelift. The primary function of dermal fillers is to add volume to the face, while the primary function of neuromodulators is to smooth out fine lines and wrinkles. The duration of fillers can range from 6-18 months, depending on the area treated. Lip fillers have a different concentration of hyaluronic acid than cheek fillers. Lip fillers are usually touched up every 6-9 months, while cheek fillers can last well over a year. An injectable enzyme can be used to dissolve the filler if it needs to be removed for some reason.
