Thank you for your question regarding if your scar will flatten. It appears you had a spiral medial thigh lift or crescent thigh lift. Also, you may have had a banana roll removal or an inferior buttock lift. Nonetheless, this scar should flatten you only three weeks out of surgery. It takes at least 6-8 weeks for scars to mature and flatten. Even then, it takes slightly longer to recover completely. I suggest you apply compression to this area and continue exercising and moving. Again, these scars will flatten. Just give it time. I hope this answers your question regarding whether your scars will flatten. I specialize in thigh lifts. I hope that I have answered your questions regarding the thigh reduction. If you have any more questions regarding the thigh lift, thigh reduction, vertical thigh lift, medial thigh lift, spiral thigh lift, crescent thigh lift, or thigh lipo, please contact my office. Please seek an experienced, board-certified plastic surgeon with significant experience performing thigh lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 thigh lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
