My weight has yo-yo'd twice in my adult life (once in my early 20s and now in my mid 30s), and I'm currently on the decline for the second (and, I hope, final) time. I'm a little concerned about loose skin because I am older and this is my second time being >200 lb. In addition to maintaining a healthy eating and exercise plan, I'd like to do as much as possible to minimize loose skin. I currently use Atralin 0.05% for acne, and I've read that retinol can help build collagen. Is it safe to apply the Atralin to my problem areas (upper arms, legs, and lower abdomen) every night during my weight loss? I expect to reach my goal weight in April 2012 (7 months from now). I plan to see a dermatologist in early 2012 to discuss lasers and dermabrasion, but I want to know what I can do in the meantime. Thank you.
