I don't know what happened but I have the joker smile now, should I stop fillers? (Photos)

This may be due to placement. Keep in mind, a combination approach is needed to get the most improvement. I recommend fillers for the folds themselves but also lifting around the mouth and cheeks to build underlying anatomical support. In our practice we combine sculptra with other fillers "layered" on top and lasers, rf treatments, J Plasma and peels to get the most conservative natural look. Please see a facial sculpting expert.

Hello!
From looking at your pictures I would say that you are a great candidate for fillers and should continue using them. I think the problem lies with the placement of the product. You have a lot of fullness in the pout of the lip but the sides become tapered and thin which gives the Joker appearance. You also have volume loss of the sides of your chin (marionette lines) that further perpetuate that look.  I think placing more product to the sides of the mouth and in the marionette area would help to soften the harshness of your smile.
Best of Luck!
