PCL Microspheres
PCL microspheres have been widely used in medical applications, especially in the field of cosmetic and plastic surgery. They can be injected subcutaneously to stimulate collagen production and improve skin elasticity, resulting in a natural-looking volumizing and rejuvenating effect. Due to its extensive range of uses, PCL microspheres hold great promise in revolutionizing medical treatment methods, providing healthcare practitioners with more accurate, secure, and efficient treatment options while simultaneously ensuring patients a more pleasant and hassle-free experience.
