I think it would some, it would also weaken the muscles that are pulling on your forehead. Do you plan to stop wearing when you are 60yo or something? I think within 10yrs they will have all kinds of crazy things that can get rid of wrinkles.
You know when they do facelifts they put strings of something down under your skin and anchor them to the skin and behind your hairline or they just slice along behind the hairline take out a strip of skin and sew it back up a cm higher. Im pretty sure that is how most are done. that is a lot more serious than using your hairpice to pull back..
