Does Anyone Have Any Information on the Corner Lip Lift (Depressor Anguli Oris-dao Release)? (photo)

I cannot find as much information on the depressor anguli oris-dao release procedure as other lip lifting procedures. Is this a good solution to folds around the lips or are there better way to address this? I was told not to use restylane as it can form weird shapes when I move my mouth or limit my mouth movement.
