Horizontal neck wrinkles develop as a result of the aging process. Stromal vascular fraction (SVF) gel, which is rich in extracellular matrix and functional cells, can be produced by a series of simple mechanical processes, including intersyringe shifting and centrifugation.

This study aimed to assess stromal vascular fraction gel in the treatment of horizontal neck wrinkles.

This single-center study included female patients with horizontal neck wrinkles (Fitzpatrick types II to IV) treated with either SVF gel or botulinum toxin type A (BTX A) injection.

SVF gel was first diffusely distributed subcutaneously along the neck line and then injected in a diluted way intracutaneously at points 0.5 cm apart along the horizontal lines.

BTX A was injected at points 1.5 cm apart (2 U in each injection site).

Satisfaction and improvement scores were compared between the two groups, and the collagen content of the neck wrinkle was compared by histologic evaluation before and after treatment.
