Differences in the application of PLLA with different intrinsic viscosities
Cosmetic and Dermatology Applications: Although PLLA is primarily used in medical settings, its derivatives or specially formulated products with controlled intrinsic viscosity can be designed for aesthetic applications like dermal fillers. Lower viscosity PLLA may be preferred for superficial treatments requiring a smoother injection and faster initial effect, whereas higher viscosity formulations can be used for deeper tissue augmentation or longer-lasting volume restoration.
Description | PLLA is a biodegradable thermoplastic aliphatic polyester, it can be completely degraded in the body. The product is excreted by metabolism and it does not have harm and side effects on the human body. Therefore our products are currently widely used in the field of medical devices, such as absorbable sutures, tissue engineering scaffolds, orthopedics, skin filling; microspheres, nanoparticles for drug delivery, etc. | ||||
