How much can I improve my thighs and butt with lipo?

Liposuction can address the "pear shape" by removing excess fat from the outer thigh/ saddle bag region.  Sometimes liposuction should be circumferential, removing inner, outer, anterior/front and posterior/back thigh to reduce volume.  Knee liposuction may further contour the legs. 

you need to post photos and it looks like you dont have much fat but you may have loose skin, so that would need to be discussed with you as to treatment for that is very different.  if not done well, the skin on the legs can sag more after liposuction and give a terrible long term result. so please see an expert leg contouring needs to be done by someone who does this frequently.
You need a formal evaluation by an expert in body shaping and contouring to determine what is best.  Traditional liposuction awake and smart liposuction are old methods and do very poorly for tightening skin or significant skin tightening or contouring.  Small problem areas can be improved slightly by these methods.  The best in body contouring not only removes fat with energy devices like VASER ultrasound but also internally heat the skin with radio-frequency devices such as J PLASMA/RENUVION, InMode BodyTite, ThermiRF to heat the under surface of the skin and tighten it at the same time as fat removal. These combinations are called 4D HIDEF VASER contouring and can only be done by a well . trained body contouring specialist. At the same time fat should be harvested, PRP and stem cells added and injected into muscles or indentations/cellulite to get body shaping and contouring.  This is known as a Brazilian butt lift when you inject the fat to the buttock for contouring and lifting, but fat can also be used in areas such as the chest/breast, arms/shoulders, calves and face.  Cellulite should also be treated with cellfina, sculptra, subcision and/or fillers such as bellafill, renuva synthetic fat, or sculptra.  If skin is very loose before surgery then it will need to be removed such as lower abdominal skin (tummy tuck/abdominoplasty), breast skin (breast lift), arm skin (brachioplasty).  Overall you need a full assessment, but simple liposuction alone will not tighten skin and needs a combination of various methods -- fat removal, skin tightening, defining, fat grafting, skin removal -- to get the best in body contouring and body sculpting.  Dr. Emer.

Thank you for your question. To provide a valid medical opinion I will need to see pictures of you body from different angles. I would suggest to be treated by board certified plastic surgeon with experience in this procedure, to get the best desired results.
Respectfully,Dr. Emmanuel Mallol Cotes.-

OK, first off your photos do not demonstrate that you are classic pear shaped, give yourself some credit! You appear fit and more revealing photos of your legs are needed in order to answer your questions with more detail.
Generally speaking, traditional liposuction utilizing small cannulas, micro liposuction, appears to be a reasonable option for you if there is extraneous fat in your legs. Extreme care and expertise is needed in someone like yourself with muscular legs and only modest fat circumferentially because overly aggressive treatment can cause skin irregularities and dents which can be hard to correct. Consult with a board-certified plastic surgeon in our area to greatly increase your chances of the best possible result. Virtual consultations are certainly an option during a lockdown.Good luck.

Photos without the leggings would be helpful. The concern in repeat liposuction of scar formation is always an issue. The disproportion of the thighs is not evident in the photos shared. If you are muscular in the legs, liposuction can not reduce the impact of this but would address excess fat, if any.
