Autologous fat is the excess subcutaneous fat cells taken from certain parts of the human body, and then the aspirated mixture is purified and injected with drugs to obtain composite fat particles, and the complete fat cells are then transplanted to the parts that need fat filling by injection, such as breasts, face, etc., to treat flat breasts, asymmetry of both breasts, superficial micro wrinkles, thin lips The use of autologous fat transplantation is used to treat flat breasts, asymmetric breasts, superficial wrinkles, thin lips, thick lips, etc. Autologous fat grafting has been used for more than 100 years in the treatment of plastic and traumatic reconstructive surgery. Autologous fat grafting has a wide range of indications, such as for filling subcutaneous depressed facial defects or deformities, such as unilateral or bilateral facial atrophy, facial soft tissue dysplasia, depressions in cheek, temporal, frontal and orbital areas, depressions caused by facial surgery or trauma, too thin upper lip or too short human middle, too deep nasolabial folds, small earlobes, etc.; for congenital breast dysplasia, breast atrophy after breastfeeding, bilateral breast size asymmetry , nipple depression deformity; for depression after liposuction, soft tissue depression in other parts of the body, such as hip, thigh, calf curvature, etc.; soft tissue atrophy of the hand (commonly known as chicken claw hand). The graft is autologous tissue, and its biological characteristics are far superior to any prosthetic material, so it is pentotoxic and harmless to itself, and will not produce immune reactions and rejection reactions.
