I bought this product elsewhere in late March and decided that I would stick with it for a while to see if it works by giving it time. Today is April 26th so it's been about 43 days since I began taking this and 2 wks ago I ordered 2 two packs of this collagen because I have noticed some hair thickness and a little plumpness in my face. I take it when I wake up every morning as it's on my nightstand and I know I won't forget. I love the product and it's very affordable and I can't wait to reap the full benefits as time goes by. I know this is a longer than usual comment but I wanted to be honest about my review and how I got here.
