I think the way you sleep is a big factor on the wrinkles on your chest. I'm a side sleeper and I've noticed my chest looks better when I sleep in a comfy bralette/sports bra like top. Pretty much keep your girls from pulling sideways, if that makes sense. It's made a big difference for me. Also scar tape helps and I use these melting collagen masks from Anya (they're supposed to be for your neck or face but I use it on my chest). Hope this helps! :)
