Has anyone had any success with firming skin or helping lessen loose skin with certain lotions? If so, which do you recommend? Has anyone tried any lotions that have keratin in them?

The one I use "seems" to firm my skin somewhat, but the #1 reason I use it is for how long it moisturizes my skin in this dry winter air (also I notice how much dryer my skin has gotten since the pre-op diet). It is called CeraVe Moisturizing Cream for normal to dry skin. They have other products in their line, as well, and I find them very reasonably priced (I think the big -16oz- tub was around $13 at Walmart). The moisture lasts all day, I mean, when I wash in the evening, you can still feel the layer of moisturizer. There is no scent, and I have found it GREAT for my face, hands, body...all over. I don't need to reapply during the day, even on my hands, unless I wash them a lot throughout the day. Let us know what you find out!

Lotion does not affect excess skin . Sorry. I found that time and regular exercise has helped the most. Even so I will always have some extra skin unless I have plastics.
