Malar Bags, which may appear as "cheek dents," generally manifest toward the outside, upper portion of the cheek area. Multiple factors may contribute to their development, among them the natural volume deflation and sagging that comes with aging and drainage problems in the small lymphatic vessels in the region. Owing to the latter, anything that affects fluid dynamics, like allergic reactions, fatigue, excessive salt consumption, etc. may worsen the appearance.of malar bags.
While malar bags are generally difficult to treat, sometimes, the restoration of volume, using a volumizing filler, such as Juvederm Ultra Plus XC judiciously injected in a 3D Vectoring pattern on the sides of the eyes, helps to pull upward and straighten the area immediately below and medial to it lessening the overall appearance of the dents. To pre-assess the potential benefit of this approach, your physician may try pulling the skin upward and outward to see if there is improvement.
Additionally, I have found that superficial placement and molding into place of small amounts of Belotero Balance, a hyaluronic acid filler, along the "dent" helps to elevate line and permit a more natural, rounded contour. The benefit of Belotero is that even when superficially injected, as typically needs to be done for this situation, it does not result in the Tyndall effect, a bluish discoloration of the skin due to light scatter often seen with other hyaluronic acid-based fillers when injected too high up in the skin.
I have generally found that this combination approach of superficial filler, particularly Belotero Balance, injected directly into the dent, and 3D Vectoring Lift of the crow's feet area to produce the most gratifying aesthetic improvement for cheek dents..
