I've been using the Sciote Vitamin C Eye Treatment ($65) for a few weeks now. I usually put it on in the morning before my moisturizer. I have used it in two ways: Sometimes I may just dab it on the orbit of the eye area, or I use it with the "Opal", a eye-rejuvenating machine which helps lift and hydrate the eye area.
I find it goes on smoothly, has no smell and is not tacky either. It dries quickly so when I need to use concealer, it seems to be dry already, so the concealer doesn't glide on as smoothly and I have to add more of it. The eye area feels tight; the circles may be a little less noticeable but not gone. It seems to reduce some puffiness in the eye area as well. I wear contacts, so I do touch my eyes a lot and this product did not bother them. I don't seem to have too many crows feet, so I would say it has helped in that area. As far as for the price, I think a good price point would be around the $40-50 range. If I used it at night, maybe the dark circles would have been better or maybe they should just call it a hydrating and firming eye cream rather then a treatment. I'm in my late 50s and still searching to discover the eye cream, treatment, etc., that will lighten or diminish my circles. I would rate it a 3.5 out of 5.
