How long do thigh lift outer dissolvable stitches take to dissolve? Also, my doctor advised me to clean these sutures with hydrogen peroxide, but I've read that this will cause them to lose strength. What is the best product for cleaning these outer sutures?I am 3 weeks post op; could my stitches be weakened by the hydrogen peroxide and how would I know if they have? Most importantly, will this affect the quality of my thigh lift result?
