Abstract Poly‐L‐lactic acid is presented as freeze‐dried preparation of 150 mg per vial and, according to consensus, the recommendation on your preparation is hydrate in sterile water for injection (SWFI) or bacteriostatic water at room temperature for ≥24 hours. (J Drugs Dermatol; 2014;13:s44) However, in these long periods of hydration, it is time‐consuming and costly for the physicians. To demonstrate the safeness of immediate reconstitution of facial biostimulation treatment with PLLA. A clinical prospective study with 26 Latin American female patients, aged between 27 and 80 years, complaining of facial laxity of treated with immediate PLLA reconstitution. One PLLA vial was injected per session in 12 mL total dilution. All patients had their pictures taken before and after the treatment in Photo Analysis Program Vectra 3D (Canfield ® ). A follow‐up 90 days was performed. The total of 58 facial applications of PLLA was reported in female patients with a mean age 52.62 (±13.46) years. Pain was reported in 17 injections (29.31%) and ecchymosis in 6 (10.34%). Also, 2 patients (3.44%) developed a nodule. None of the patients presented significant bruising, edema, or papules formation. Despite the literature declare that a longer hydration times (up to 48 hours) have been shown to reduce the risk of nodule formation (Aesthet Surg J; 2011;31:95), our study demonstrated the safeness of injection with immediate reconstitution and a very low adverse events rate. Immediate PLLA reconstitution is a great asset for physicians, injections in account of being less laborious, less time‐consuming, and reducing product loss for the injector.
