Introduction
The difference between fat and fat gel used in facial fat filling lies in their sources and processing methods, tissue structures, duration of effect, absorption rates, and recovery periods. Generally, fat has good biocompatibility, lasts longer, and requires a longer recovery period. In contrast, fat gel has relatively poorer biocompatibility, also lasts longer, but has a shorter recovery period.
Generally, facial fat grafting involves filling depressed areas with fat or fat gel. The usual reference price for facial fat grafting ranges from 3,000 to 10,000 yuan per session, with noticeable improvement typically visible within 7 to 15 days. The main differences between fat and fat gel used in facial fat grafting lie in their sources and processing methods, tissue structures, duration of effect, absorption rates, and recovery periods. A detailed analysis is as follows:
1. Differences in Source and Processing
Fat mainly comes from areas such as the abdomen or inner thighs and contains oils. Fat gel, on the other hand, is processed from extracted fat into small fat particle clusters through special treatments, such as purification.
2. Differences in Tissue Structure
Fat mainly consists of fat cells and fibrous tissue. Fat gel generally consists of adipose-derived stem cells and other active components, such as various growth factors.
3. Differences in Duration of Effect
Fat grafting primarily involves transplanting fat cells, which can survive easily and offer longer-lasting effects, potentially lasting 1-3 years. Fat gel contains more growth factors and is easily metabolized, resulting in shorter-lasting effects, typically lasting 6-12 months.
4. Differences in Absorption Rate
After fat grafting, there is less likelihood of rejection reactions with surrounding tissues, better biocompatibility, and a slower absorption rate. Fat gel has poorer compatibility with surrounding tissues and is absorbed more quickly.
5. Differences in Recovery Period
Fat grafting has relatively minor side effects but requires a longer recovery period, usually taking 1-2 weeks for full recovery. Fat gel recovery is shorter, with natural appearance typically restored within 3-5 days.
Prior to undergoing fat grafting, it is recommended to consult with a doctor to understand your individual condition before selecting the appropriate material. Additionally, to ensure safety, it is advisable to undergo the procedure at a reputable hospital.
