Prostrolane Inner B

Prostrolane Inner B

Innovative Dermal Filler with Sustained Release Technology & Novel Peptide Technology for reduction of localized fat accumulations.



Many people around the world are suffering from obesity because of eating habits, lack of exercise and/or congenital problems. Lipolysis is one of the most difficult clinical parts to solve effectively in the medical esthetic field.  Although many lipolytic products have been on the market for a long time, they were not meeting patients’ needs due to their poor efficacy and side effects.

With noble lipolytic peptides and its sustained release technology, we developed very safe and effective product which can give the most satisfaction to patients and doctors.

Caregen has been accomplished remarkable research achievements in targeted fat reduction and has developed Prostrolane Inner-B.
Prostrolane Inner-B is a sterile medical device, dermal resorbable implant that contains a Sodium hyaluronate and peptide complex (Nonapeptide-32, Pentapeptide-43, Tripeptide-41, Octapeptide-11). Prostrolane Inner-B is a transparent gel supplied in a glass syringe. The product is for single use only.

Site of application:
Face (double chin, jowl), abdomen, upper arms, love handles, thighs and knees.
Prostrolane Inner B injectable gel is indicated for deep dermis implantation for lipolysis of moderate to severe double chin, abdomen, buttocks, back of the thighs.

Active ingredientsActive ingredients:
– Nonapeptide-32: Promotes the metabolic cycles of glycolysis and gluconeogenesis.
– Pentapeptide-43: Decreases lipogenesis and promotes lipolysis.
– Tripeptide-41: Stimulates lipolysis and promotes cell regeneration of tissues.
– Octapeptide-11: Activates cell regeneration. Improves the appearance and tone of the skin.

Prostrolane Inner-B performs targeted fat reduction through activation of AMPK, PKA and ERK pathway which strongly increases lipolysis in accumulated lipid droplets by phosphorylation of ATGL and HSL, (increases secretion of triglyceride, free fatty acids).
In addition, Prostrolane Inner-B stimulates AMPK phosphorylation which leads inhibition of Lipogenesis by preventing PI3K-AK phosphorylation which is typical signaling pathway of triglyceride synthesis.

Looking at the benefits of Prostrolane Inner-B
1) The size of adipose tissues are reduced without fat cells necrosis, so the side effect is dramatically reduced compared to other products.
2) The product can give continuous and most effective lipolytic effect for 2 weeks with one injection.
3) The formulation is very soft which gives minimized pain and super comfortability to patients and doctors.
4) Unique and exclusive patented technology makes it difficult for competitors to copy, so it can have a
unique market position in the market.
5) The Product accelerating lipolysis, at the same time, and strongly down-regula ting lipogenesis.


Prostrolane Inner B injectable gel is indicated for deep dermis implantation for lipolysis of moderate to severe double chin, abdomen, buttocks, back of the thighs. Prostrolane Inner B lipolysis injection aims for reduction of localized fat accumulations.
