What's the difference between Stylage M or L and Revanesse Kiss?

Hi there, The dermal fillers you mentioned in your post are all hyaluronic acid based fillers, however they differ based on factors such as cohesiveness, thickness, duration/durability. These characteristics determine the outcome of your treatment. The important thing is to be sure that you’re injector has the knowledge and expertise necessary to choose the filler and the technique that will give you the full, natural look you are hoping to achieve.

There are many HA fillers approved for dermal filling in Canada. Each company has a portfolio of products with characteristics designed for different indications. It is important that you know what products are used but you need to trust the knowledge, credentials and experience of your provider to make the best choice for you. No manufacturer can claim superiority of their products but choosing products with a longer history of use and more scientific study is an important factor in making recommendations to my patients. Neither of these products would be my first choice. 

Most brand of dermal fillers have different fillers within their portfolio that will differ in thickness, cohesiveness , lifting  etc.. If you are looking for fuller but softer and natural lips I would personally choose Stylage M or Juvederm Volift ( called Vollure in USA). However, the experience of the injector is often more important than the filler itself. All the best, Dr.Michon
