Love the roller applicator [SEP] (Reviewed by my wife): I love the roller applicator of this under eye treatment.  It makes applying the product very easy and helps avoid wasting product.  The eye treatment smells great and goes on smooth.  It moisturizes well and leaves a little shine, reducing the appearance of dark circles and lines.  It is not a miracle product, however, and it does not get rid of really dark circles like the ones I have around my eyes.
