I cannot say enough about this product...I absolutely LOVE IT!!! I received this product as a free sample with another product I ordered on Amazon (Oleavine rice-based phytoceramides-oral capsules), and I thought it was from Oleavine, but after contacting them about wanting to order, they said they were not going to be offering it. (I think I know why as it is NOT their product), however I was so impressed with these I searched and searched the Internet. All I could find was Elizabeth Arden's and didn't want to pay the $70+ for 30 day supply (having 2 boys in college). Finally in my determination, I found these on Amazon and much to my delight it was the same formula (which I compared with & like better than Ardens) & the same capsule design as my free samples and at HALF the price of Eliz.Arden's!!! I was so happy & ordered right away.I have been using this product for about 2 weeks now (including my free samples) and I've never seen a product work instantly, but this does! My skin is instantly softer than it has ever been, literally like silk! I have been taking phytoceramides orally for over a year now & could see & feel the difference in my skin, but had no idea that a topical ceramide serum would provide such results. I use this product in the morning after cleansing, toning, & vitamin c serum. It goes on a bit greasy, but absorbs in about a minute. Then I apply my moisturizer & makeup. I had a couple of fine lines around my eyes & this product has made them disappear as well as evening out skin tone. I also have some fine lines around my mouth & a little patch on my neck & I can see this product is helping with those as well. I will happily order more of these when a refill is needed. I have not experience any irritation at all, even around the delicate eye area. BTW, I tanned alot in my youth and for many years really didn't do much for skin care except cleanse & moisturize, but over the past year & a half I have been diligent about my skin care (except sometimes I still fall asleep with my makeup on), but I have really seen results, so it's never too late! I am now 47 and while I do see a much more youthful look to my skin, others tell me I look in my 30s, so I will take their word for it :D (and of course continue using this!)
