I like this. It doesn't cause any breakouts, it makes my skin feel noticably firmer and is great under make up. You need to use a very small amount so I think the bottle is going to last a long time.
This stuff is FANTASTIC! The Holy Grail! I used it to look a little firmer, and realized it works on my adult acne. I find most products to be disappointing: they don't do anything. With this one, I saw a difference within about one week. Highly recommended!
