How Long Does Teosyal Usually Last?

Teosyal products can last approx 6 - 18 months depending on which Teosyal product is used. The longevity varies between patients. Hope this helps.

There are several products in Teoxane's Teosyal product range. They have different uses and different duration of actions. When you have hyaluronic acid filler injected you also have collagen and elastin formation within the product. This enhances the duration of action. However, at the same time your body's ageing mechanisms are working against this so there will be personal variation in the duration a filler will last. 
Teosyal Products
1) Ultra Deep used for volume enhancement. eg Cheek, chin, temple. Lasts 9-20 months
2) RHA 4 Volume in dynamic areas as well as cheeks and facial contours. Lasts 12-22 months
3) RHS 3 / Global Action / Deep lines - Deep dynamic wrinkles, Nasolabial folds, marionette lines 12-20m 
4) RHS 2 Moderate dynamic -  wrinkles forehead and glabella.  9-18 months
5) RHA 1 fine dynamic wrinkles, neck, décolletage, bar code wrinkles in skin. 9-12 months
6) Redensily I  Hydration and prevention of the signs of ageing on the face, neck décolletage. 3 sessions at 3 week intervals, maintenance 1 session 3x a year. 
7) Lip fillers - using Teosyal Kiss, RHA 3 or RHA2 depending on the volume needed and the dynamic stretching of product due to the area. Lasts 6-9 months.
In my opinion if you take the minimum duration and add 3-6 months onto this (apart from lip treatment) this will give you the typical product duration for most people. 

Teosyal has a very similar "lifespan" when compred to other fillrs such as Restylane or Juvederm.  In the cheeks it last about a year.  In the smile lines and around the mouth it last about 6 months.  It varies which each individual and area injected.
