The jury is still out on this product. I love No7 products but I just am unsure about this one. I THINK it might be making a difference so I plan on finishing it. I guess time will tell. 

I've been using this for about 2 weeks now. I have seen some difference. Nothing drastic.

I really didn't expect this to work, I was very skeptical but IT WORKS the puffiness has decreased...not gone totally, but my eyes look so much better with this product!!!

Noticeable improvement after multiple day use. Enjoyed the cooling sensation of applicator. Some product lost between the beads of the applicator. Easily twists from off to on.

7 days in and I am starting yo see results. I will continue to use this product as recommended and update.

It has taken at least 2 weeks to see any significant change, but it does seem to be reducing the dark circles.

I’ve been using this for about 3 days now it says noticeably lightens dark circles within a week mine are bad so I’ll give it two weeks I caught this on sale at Ulta and snatched it up I love this brand they have great products that actually work and aren’t too expensive so far not much difference though in my opinion we will see in an few more days so far though I’m really liking how my under eyes feel after using it

I have sunken under eye circle which creates some lines and shadow, also puffy above sunken area. This product is the only one that helps with that. Not a dramatic effect like what you see in women with injections, but enough for me to notice. It depuffs and smoothes out my undereye. It almost tightens the skin. Trick is to work fast before the product dries. Use a small amount. If not, it peels off. I use the applicator to spread the product, and tap lightly with my finger. One eye at a time. I'm an Asian with yellow skin, and medium to dark works perfect. Love this and will continue to use. Please don't discontinue!

I've never used a dark circle corrector before, but tried this one. It is great. It lessened the appearance of the darkness around my eyes. My skin appeared firm and plump. I was afraid it would irritate my skin, but it didn't. It's mild enough for people with sensitive skin.

I've added the no7 dark circle corrector medium/dark to my facial routine. It's smooth and blend well, not oil or harsh.
