Lipo and weight loss, left with saggy, lumpy arms. How can I improve the rippling? (Photos)

I posted a question about my arms previously but inadvertently left out what may be important information. I have lost a considerable amount of weight over the past 3 years. Approx a year and a half ago, prior to weight loss, I had lipo on my upper arms. Now my skin is saggy and lumpy/rippling. Is there a treatment that could improve the appearance of my arms, I can almost deal with the sag but the rippling really bothers me
