How can you make your skin smoother and firmer?

I%26#039;ve lost a pretty decent amount of weight over the course of a pretty decent period of time ... the only problem is, I have all of these old stretchmarks (the white ones) and my skin%26#039;s not very smooth .... it doesn%26#039;t have the springy element that makes it stay back in place and whatnot. Any suggestions/remedies?|||Drink lots of water and do facial exercises. There are lots of books printed about facial exercises. It would be too complicated to explain here.|||tRY APPLYING OIL BEFORE A BATH. DO NOT USE SOAP.|||OH I%26#039;m sooooo glad you asked that because I just bought these mary kay products for about 60 bucks.
