What Lecithin Injection is and what it is used for?
Phosphatidylcholine, the active ingredient of Lecithin injection, is derived from soy bean
lecithin. Chemically, the phosphatidylcholine molecule consists of a head group
(phosphorylcholine), a middle piece (glycerol), and two tails (the fatty acids, which vary). The
phosphatidylcholine molecules present in the tissues of organisms may vary depending on the
radical of the fatty acid linked to the molecule.
The injectable lecithin is clear yellowish liquid, free from visible particles.
The Lecithin Injection is used in:
-Body slimming: Loss weight
-Obesity treatment
How does Lecithin Injection work?
The most widely recognized action mechanisms for phosphatidylcholine are those of an emulsifier and tensoactivator. Phosphatidylcholine behaves as a detergent in the subcutaneous level, causing nonspecific lysis of fat cell membranes. Phosphatidylcholine has been shown to reduce the systemic levels of cholesterol and triglycerides.
How to Use Lecithin Injection?
The technique used for body slimming and obesity treatment was subcutaneous infiltration with undiluted lecithin (250mg/5ml).The injection was injected into the fat deposit following a multi-injection pattern according to the shape of the fat deposit. The amounts of lecithin injected into each fat deposit ranged between 5 ml and 30 ml per application according to the individual needs of the patient.
For the detailed injection parts and dosages, please see the table here below.

Abdomen/waist/hip

Inject 0.7~0.8ml on a spot and move to next half an inch or a centimeter distant.

|
Face (double chin)

For those areas with small fat deposits were infiltrated at only one central
point, whereas in larger areas, the injections were at equidistant points of
approximately 1 cm. At each application site, 0.2ml was injected, totaling 0.2
to 5.0ml (10-250mg) per session

Other parts such as
armpit, upper arm,
back and thigh
|
Adjust (mostly less than abdomen/waist/hip) injection quantity according
to the obesity degree of the part to be injected.

It does not matter if there are any particles present in light inspection, just shake well before Use.
Possible side effects
The common side effects are pain, swelling and erythema, which typically lasted for 2-3 days. Haematomas also occurred in some patients.
No serious side effects or complications were noted in clinic. Using the correct technique, injecting lecithin may be a safe and efficacious alternative to liposuction in patients objecting to surgery.
