Abstract
AestheFill, a biostimulator containing poly-D,L-lactic acid (PDLLA) microspheres and carboxymethyl cellulose (CMC), is supplied as lyophilized powders in vials. It must be reconstituted with sterile water for injection into homogeneous suspensions before administration. In AestheFill, PDLLA microspheres do not dissolve in water, while CMC acts as a suspender for the PDLLA microspheres. However, CMC tends to form lumps when introduced to water. Agglomeration technology is utilized to prevent the formation of CMC lumps during reconstitution. This is why the lyophilized powders of AestheFill are agglomerated into granules. Reconstituting these granules involves several steps: wetting, sinking, disintegration, and dissolution. In this article, we summarize six different reconstitution methods for AestheFill. Additionally, our analysis identifies two key, time-consuming processes: the hydration of lyophilized granules and the dispersion of CMC and PDLLA microparticles.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

期刊介绍:
Aesthetic Plastic Surgery is a publication of the International Society of Aesthetic Plastic Surgery and the official journal of the European Association of Societies of Aesthetic Plastic Surgery (EASAPS), Società Italiana di Chirurgia Plastica Ricostruttiva ed Estetica (SICPRE), Vereinigung der Deutschen Aesthetisch Plastischen Chirurgen (VDAPC), the Romanian Aesthetic Surgery Society (RASS), Asociación Española de Cirugía Estética Plástica (AECEP), La Sociedad Argentina de Cirugía Plástica, Estética y Reparadora (SACPER), the Rhinoplasty Society of Europe (RSE), the Iranian Society of Plastic and Aesthetic Surgeons (ISPAS), the Singapore Association of Plastic Surgeons (SAPS), the Australasian Society of Aesthetic Plastic Surgeons (ASAPS), the Egyptian Society of Plastic and Reconstructive Surgeons (ESPRS), and the Sociedad Chilena de Cirugía Plástica, Reconstructiva y Estética (SCCP).
Aesthetic Plastic Surgery provides a forum for original articles advancing the art of aesthetic plastic surgery. Many describe surgical craftsmanship; others deal with complications in surgical procedures and methods by which to treat or avoid them. Coverage includes "second thoughts" on established techniques, which might be abandoned, modified, or improved. Also included are case histories; improvements in surgical instruments, pharmaceuticals, and operating room equipment; and discussions of problems such as the role of psychosocial factors in the doctor-patient and the patient-public interrelationships.
Aesthetic Plastic Surgery is covered in Current Contents/Clinical Medicine, SciSearch, Research Alert, Index Medicus-Medline, and Excerpta Medica/Embase.
