The L'Oreal Skin Genesis eye serum ruined my face....I used this product about a year in a half ago, and it has changed my skin forever. Sure some people would love to get rid of dark circles under their eyes but thats not what I had in mind. I have not been able to tan under my eyes ever since I used it for only a month of use no less. I am so disappointed in this product, I even contacted L'oreal and they offered no suggestions to help reconcile this situation. I have a feeling it contains a bleaching agent. I am only 30 and used this as a preventative mainteance type thing. Never had a problem...
