I was looking for a new serum. I had previously tried Graydon's face lotion, Skin Stuff(which I also love), and thought this could be a good option. It is light weight and silky and I literally noticed a difference over night but wanted to wait to review to see what happened over time. It is lighter than what I had been using before and was initially worried. When I think back, I actually felt the same about their lotion. The smell is subtle but fresh and lovely. I use it morning and night and after about 2 weeks my skin is feeling more hydrated and noticeably happier(I had been without a bio-retinol for a month or so). I always know when something is a keeper when I'm excited to use it and other people notice my skin. Two thumbs up from me - definitely worth it and the added bonus for me is I can use the same serum morning and night and it doesn't contain a whole bunch of scary ingredients. Im excited to try the rest of their products!
