Which is best to use for wrinkles around the mouth, and whst is the average cost?

I recommend a combination approach to get the most improvement for this area. 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. Cost will vary. Please see a facial sculpting expert. Best, Dr. Emer

There are various treatment options depending on multiple factors such as how deep the wrinkles are, whether the lines are there at rest or only with movement, etc. I'd suggest a proper in-person assessment with your dermatologist. A filler is often a great option (e.g. Restylane fine lines, Juvederm Ultra or Volbella, Redensity-II), sometimes alone or with a little bit of Botox. Laser resurfacing or microneedling are also good options for improving the texture/tone of the skin around the mouth. Cost is variable, depending on how much product is needed, which treatment is selected, etc. The choice of an expert physician injector such as a dermatologist to optimize safety and to give the best, natural looking and symmetric results possible is the most important factor.
