Lissolis is not a muscle,

Mainly the adipose tissue in front of the cheekbones. Its position is an inverted triangular tissue 2 cm below the eye. When you smile or make an expression, you will bulge slightly because of the extrusion of facial muscles, just like a round and bright apple, hence the name "risorius". For example, the goddess scene of online celebrities, the girl who goes against the sky is her greatest weapon.

Lissolis will shrink with age and look old. Risorius can restore fullness through plastic filling, which can make people look young. Some beautiful women have delicate facial features and good skin, but because they are thin, their faces are bony and lack the softening of fat before cheekbones (that is, risorius), they feel more inaccessible.

Because the position of cheekbones and Li Souris is very close, many people are silly and can't tell the difference between them. The real risorius is not muscle or bone, but adipose tissue under the cheekbones. Only when you smile can you see a small bump. Because the cheekbones are too close to Risolius, many people will be confused.
