Perlane is an FDA-approved dermal filler for implantation into the skin for the correction of moderate to severe facial folds and wrinkles, such as nasolabial folds. Perlane is generated by a Streptococcus species of bacteria.
Perlane differs from Restylane primarily in the size of the particles and the depth of the required injection. Perlane, used for deeper wrinkles, has larger particles that are injected deeper into the skin than Restylane. Perlane is not approved for use in lip enhancement, but Restylane can be used for this purpose in patients 21 years of age and older. Clinicalstudies showed no significant differences in the safety of Restylane and Perlane.
Perlane is comprised of biotechnologically engineered, non-immunogenic, stabilized hyaluronic acid gel particles. Hyaluronic acid is a natural substance found in all living organisms and provides volume and fullness to the skin. The three-dimensional gel particles in Perlane are hydrophilic molecules, attracting and binding to water molecules as they degrade, helping to maintain volume augmentation for about six months.
Perlane should only be administered under the supervision of a licensed practitioner.
Perlane Clinical Trials
Four U.S. clinical trials in over 500 patients were completed in support of the approved uses for Perlane. These trials evaluated the safety and effectiveness in mid-to-deep skin injection for correction of moderate to severe facial wrinkles and folds, such as nasolabial folds.
Perlane was shown to be effective when compared to other dermal fillers with respect to the correction of moderate to severe facial folds and wrinkles. Studies showed that at three months roughly 87 to 92 percent of patients reported an improvement in wrinkles, and at six months 63 to 71 percent of patients were still reporting improvements.
