Why did you pick this product vs others?: I have been using this product for 2 days and can see a difference in the appearance of my skin. 40+ this does help with fine lines. I can already see my smile lines appearing less noticeable. A little goes a long way. You don't need to use a lot, or it will look like clown makeup, and you will have to work it in, but it is not a big deal. Also, if you have sensitive skin, I wouldn't buy a product clearly listed as extra strength. It will work as an extra strength product.
