1. Fat filling failed. Due to the serious technical foundation, the forehead fat filling is excessive, and there is a phenomenon of longevity. After absorption, the local filling is uneven, and the fat necrosis produces a lump after local filling. These phenomena can be repaired. In these cases, fat can be dissolved and liquefied by cortical light welding (laser fat melting), so that excess and necrotic fat can be excreted. Cortical light welding can make the skin compact, restore the elasticity of fat-filled skin and avoid wrinkles.

2. Due to too much single filling, the amount of fat filling depends entirely on the doctor's experience, and less filling may affect the surgical effect because the fat is absorbed; And if it is filled too much, there is a risk of fat contracture. Experienced doctors and formal procedures are the key to the success of autologous fat filling. Everyone's body absorption is different, and how much fat can survive depends on the operation: liposuction is mild and does not damage fat, and the purification process does not damage fat cells.

Hard lump after liposuction:

1. Improper liposuction by doctors causes local hematoma, and scar contracture and hyperplasia are formed during recovery;

2. After the operation, the pressure is too strong, the effusion is blocked, and the skin is hard;

3. Liposuction does not completely suck out liquefied fat, forming cellulite.
