Vacuum-assisted Hydration before the Back-and-forth: A Novel Accelerating Method for Reconstituting Injectable Poly-D,L-lactic Acid

Abstract: usually <1 minute. (See Video [online], which displays the employment of the VAH method with subsequent back-and-forth method for reconstitution of injectable PDLLA.

“…7 It can be quickly prepared by vacuum-assisted hydration and then the back-and-forth reconstitution method. [7][8][9] Its unique properties of quick preparation, easy injection and adjustable thickness make PDLLA an ideal filler for this method. We recommend wide placement of the filler, not just correcting the "troughs" or "grooves."…”

“…Reconstituting injectable PDLLA with sterile water for injection (SWFI) to form a homogeneous suspension is needed before injection. [1][2][3][4][5] In our past experience, we often use SWFI from 1.5 to 24 ml to reconstitute a vial of injectable PDLLA for a wide range of applications such as from deep injection for volume augmentation to superficial injection for skin quality improvement.…”

“…This method is based on the fact that when the amount of the suspension is diluted by SWFI to its double fold, the density of this suspension halves. First, we use vacuum-assisted hydration 5 and the back-and-forth method 3,4 to reconstitute injectable PDLLA into a thickest suspension. After taking the required amount of this thickest suspension for injection, we dilute the residual amount of this suspension by the same amount of SWFI.…”

“…Considering that the hydration time of the PDLLA lumps is a crucial step in the reconstitution process, in 2021, they introduced an even faster "vacuum-assisted hydration" (VAH) prior to the back-and-forth technique, which only takes less than 1 min. 5 In 2023, Victor Cheong modified and proposed a different VAH method. This article aims to introduce this new method and compare it with the previous VAH method.…”
