The apple muscle is not a real muscle, but it is a raised tissue located in the core area of the face, underneath the front of the zygomatic prominence. A girl with apple muscles gives her cheeks an apple-like curve when she smiles, creating a sense of femininity and approachability. It is because of the sweetness of the apple muscle when smiling that the apple muscle has become a new coordinate of fashion. So what are the apple muscles? The apple muscle is a collective term for the muscle, fat, and other tissues located 2 centimeters below the eyes, giving the appearance of an inverted triangle. When smiling or making an expression, this area bulges slightly due to the squeezing of the surrounding muscles, looking like a rounded apple, hence the name apple muscle. As we age, the skin loosens and shrinks, and the apple muscle inevitably sags and sinks. When the apple muscle loses its original roundness and firmness, not only will it look old, but it will also give people an unacceptable sense of meanness because of the high cheekbones. At this point, there is a need for apple muscle augmentation. Many beautiful women use fillers to create a youthful and lovely appearance of the apples, making their smiles even sweeter. Fat is the best filler for the face, and by grafting it to the apples, it can bring the original elasticity and softness to the apples. Fat grafting to fill in the apple muscle has a high survival rate, lasts for a long time, and improves the skin texture of the skin that has undergone fat grafting, making it an ideal filler material. Tear trough is the “pain” of many beautiful people, it is a groove caused by the atrophy of soft tissues at the lower edge of the orbital septum, which often extends from the inner corner of the eye to the lower orbital rim. The appearance of the tear trough may lead to more obvious bags under the eyes and dark circles under the eyes, making people feel haggard and affecting aesthetics. Fat grafting, on the other hand, can fill in this indentation and eliminate the tear trough.
