I said I would buy again, but I'm not 100% sure. Don't get me wrong - this is a great product. Nice serum in a glass bottle with a glass dropper. Makes my skin feel so soft. I'm just not sure if I'm getting any kind of "firming" from it but maybe if I keep using I will see results. There are no colors or fragrances in their products, but in some of them you can smell natural ingredients in them. I'd rather have them smell natural! The bottle of this serum is going to last me forever, too. I've also been putting it on the backs of my hands.
