Well I am not really sure why exactly this is called twenty four hour eye repair serum because it most definitely does not work that quickly. I applied it to my puffy mildly wrinkled eyes, and have yet to be amazed by it. After quite some time of use there was a reduced swelling and less puffiness in my eyes. It doesn't do much for the wrinkles that I do have so I can't imagine that it would do anything at all for people older than me. (I'm twenty) In my opinion this is just a cheap knock off version of other products and you shouldn't waste your time on it. It makes a lot of fancy promises but sadly does not live up to them by a long shot. Effectiveness I probably wouldn't end up buying this again or recommending it to anyone. It is a cheap imitation product which is surprising for this brand since I have used other products by them that worked pretty well. This isn't one of them though so skip it.
