Olay Regenerist is my favorite line of beauty products geared toward facial care. I love this Eye Lifting serum just as much as the other products in the line. It works so well to help lift the skin underneath my eyes, I could not imagine switching to another product or brand. In just one week I noticed a dramatic difference between before I used this product and after. It not only reduced the sagginess in my skin, it also reduced the appearance of the darkness. I simply apply once per night before I go to sleep and voila, results! The cream absorbs very quickly. It is so gentle on the skin. I have not had any problems with any kind of irritation. I even got it in my eye on accident once and it stung for a second, but my eye did not even turn red. I have missed a few nights here and there and it is not like the effects wear off without continued use. I love this stuff and recommend everyone give it a try.
