The biochemical theory of diamond lock cells originated from Scripps Institute in the United States and was developed according to the discipline of anti-aging genetics. Autologous fat was extracted and cultured in the national GMP standard laboratory. Active cells and various growth factors were mixed with autologous fat and injected into breasts in layers. The survival rate of active cells was over 95%. The extracted autologous cell tissue has good compatibility and reproducibility, so there is no need to worry about the chest not being high enough or stiff and unnatural after cosmetic surgery.
