Does it matter whether you use a needle or cannula to fill in acne scars with dermal filler on the cheeks?

In our practice, broad based, depressed acne scars may be corrected permanently with microdroplet Silikon1000. These injections are superficial, and the filler is placed just below the scar with a small needle. I cannot imagine using a cannula for acne scar treatments. Thank you. Dr Joseph

I use cannulas for several purposes when injecting fillers into the face.  Acne scars are better injected with a needle so that subcision of the scar to release the scar tissue and create a pocket for the filler can be performed prior to injection of filler.

Acne scars can be treated very effectively if multiple techniques are used. Before injecting any filler, I like to use a cannula to diffuselynumb and subcise and then use a needle to go after stubborn individual strands of fibers tissue that contribute to the scarring. I can then lay down a thin layer of filler under the subcised scar with a cannula and then inject into the skin right underneath the individual scars with a needle. I prefer to use Bellafill® for this because it is more permanent and it is FDA approved for treating acne scars. Combining this with PRP and laser treatments will further enhance the outcome. Acne scars are tricky to treat, but we can get some very nice results using the right combination of techniques.
