How can I improve my skinny ankles? (photos)

I do more calf and ankle liposuction than anyone I know, I am suprised you would want fat injected to this area.  As people age them seem to want more contouring and thinning below the knee.  Fat injected here would help but has the potential to be lumpy unless harvested with a very gentle smooth method like with water assisted harvesting (Body Jet is an example).  PRP along with the fat will keep it lasting longer.  I suggest only seen an expert for this type of treatment.  Best, Dr. Emer.

Interesting question. Requests come in more often for the opposite as certain ethnicities (Asian females) can be victim to "cankles" where they do not like how their calves taper too subtley to their ankles. In short, yes, fat grafting or placing a custom implant would work. Custom implants would likely leave a scar, though. Fat grafting has an advantage of being permanent without leaving scars. Post operatively,  You would have to keep your legs elevated without any compression to the area for several weeks - this is something to consider. Another non-surgical alternative would be Botox for your calves to shrink down the muscle there so that it may be in better proportion with your ankles. There are lifestyle adjustments to this, however. Best to see a board certified plastic surgeon in person  to discuss your goals.
