So I discovered StriVectin has this 30-day trial offer where you can order a 1 0z. StriVectin-SD sample for free just pay shipping of $6.50! (This a $34.50 Value!) They say the 1 oz. size is enough for 4 weeks of use, I am assuming on your face of course. This is an awesome deal and a great way to try an expensive product before you buy and also a chance to really use it and have a chance to see results first. I received mine today and I am excited to try it out. I am all about anything that can prevent or help improve signs of aging! If you would like to try it for yourself go here http://www.strivectin.com/freetrial and sign up for yours!
