Only used a few weeks, but do see benefits....I don't have much puffiness but does seem to "iron out" small wrinkles. Tho I use eye moisturizer over it and not sure if that's ok, directions don't indicate if ok. Found another product also good, Wunderlift, which much cheaper, but I believe Genucel more effective.
The plant cell therapy is excellent... however, the two "instant" puffy eye products didn't work for me and pill up if you put it under or over makeup.
