Looks like you have lost a considerable amount of weight.  You should be congratulated--not easy to do.  The bad news is that further weight loss will not improve your considerable skin laxity.  The only answer is to remove all of that excess skin with an abdominoplasty (tummy tuck).  There is no definite minimal age.  Surgeons look at overall physical condition, degree of skin laxity, and maturity when deciding who and who not to operate on.  If you're healthy and have realistic expectations and are willing to accept a scar, looks like you might be a very good surgical candidate.  Your abdomen would look significantly better following a tummy tuck!  Good luck!
