The wrinkles in this area are simply folds due to the need for mobility in your legs. It is a very normal finding. However, if you wish to reduce the laxity in the skin, then skin tightening with microneedling radiofrequency such as Morpheus 8 or Fractora could assist in this. I do not recommend fillers to smooth these wrinkles as they may add bulk to the area and appear bulky or rub on your underwear line. I am not a plastic surgeon and cannot state much about thigh lifts other than they leave awful scars on many patients and are typically reserved for those who have a LOT of laxity in the skin due to excessive weight loss. As a gynecologist, your labia majora appear normal.
