Abstract
Aim: An ideal injectable material would be biocompatible with long-lasting effects. The relative polymerization and chain
length of the compound determines its viscosity, as measured by centistokes (cp). It is available in 350, 1000 and 5000
cp - the higher the number, the more viscous the oil. Most of the reports used 1000-cp silicone oil for filling purposes and
due to high viscosity, only microdroplet injection technique is recommended to avoid complications. This is the first report
of patient series using liquid silicone with a 350-cp viscosity The objective of this study was to explore the reliability and
efficacy of low viscosity liquid silicone for lower face contour correction.

Methods: Lower facial region of 43 patients including chin, nasolabial and melolabial regions were treated by low viscosity
(350 cp) liquid silicone. Instead of microdroplet tehniqe, retrograde linear threading technique was used. Total injection
volume was 6.0 ± 3.9 mL. At least two sessions were required for complete correction which are spaced one month apart.
Overcorrection was avoided. The treated areas had a soft and natural feeling with no lumpiness and stiffness.

Results: Mean follow-up period was 16.8 ± 14.3 months. The mean aesthetic satisfaction score was 4.51. No migration of
the material was seen which is revealed by palpation and no major complication was encountered. None of the patients had
any complaints regarding late facial deformity due to silicone migration.

Conclusion: Low viscosity liquid silicone is effective, well-tolerated and easy to use. It can be used as an alternative to
higher viscosity silicones to avoid technical errors and complications.
