Can massages under the eyes, in the "bags" or "hollows" area, improve the appearance/improve the skin?

There are sites where people swear it works for them, but I worry it may just be wishful thinking? They say they massage the area pretty rough even, and it greatly improves the appearance. Supposedly it improves collagen production, but I know none of them are really experts. I worry; Isnt this area delicate, or could there be some truth to this? I know this is a site for surgical answers, but I'm looking for.something more subtle and natural, and sometimes these things actually work. thanks!
