I just had a talk with my doctor yesterday about this very subject.
NO...there is nothing that actually helps. Yes, it CAN tighten some over time, but the older we are (don't know your age, but I'm at 40) the less elastic our skin is.
She told me there are no "products" that will help the situation.
In the end, the only alternative is surgery. (she's not a surgeon, so it wasn't like she was pushing for that)
And then she said, "GOOD FOR YOU!" that you have this problem now.
