Hi, April.
There are many products out there that would help with stretch marks and sagging skin. I have to say that I recommend the Avon lotions for stretch mark reduction, tummy tucking, thigh reduction and breast firming. Of course, that's because I am an Avon representative. If you want more information about these products, you can check my website at
www.youravon.com/joneil or contact your local Avon representative.
I do recommend that you research any other product first, however. You can go on-line and do a search at Yahoo.com or Google.com to find out there are any negative (or positive) articles about each product written by credible medical professionals.
Hope that helps you with your concerns. Congratulations on your weight loss to date and good luck with your future endeavors!
