Although it didn't help with my dark circles like advertised, it works wonders in reducing puffiness, especially if using it in the AM like I usually do. I actually apply it all over my face, leaving it feeling smooth and great overall, also thanks to its consistency, which is almost gel-like and not greasy at all.

Around 3 weeks of application, so here's my thoughts.

The good:
* effective for my puffy eyes. my main concern upon buying is actually my puffy eyes. i can see that this has visibly reduced my puffiness.

On the fence:
* not sure if it does anything for my dark circle. i don't have a very distinct dark circle to begin with, so its hard to tell.

The bad:
* mild irritation for the first few days of application. maybe i used a tad too much? but there's no more irritation after that few days.

Ive been using this for a few weeks now, every morning and night. But i still have not really seen a difference in my under eyes. i will continue using it though. there is no harsh scent and it feels nice and makes my under eye area soft and hydrated. I just wish there was more of a difference. i still have bags and dark circles

I decided I needed something to help with the dark circles in my under-eye area.

As I have combination skin (oily T zone & dry cheekbones + under eye area) with vascular rosacea (hence, sensitive skin), I needed something that fitted in with my skincare.

Having note that my skin does not flare up when exposed to Citric or Lactic Acid (which this product contains), I decided to give it a try.

BEST decision ever made!
It not only reduced my under-eye dark circles (please inform yourself before purchasing this for this specific issue, as it might be caused by a multitude of issues, that no product could ever fix!), but because I decided to use it on my entire face (I mean, hello! It has: Maltodextrin, Caprylyl Glycol, Glycerin & Glycine Soybean Seed Extract [these 2 being very good for my dry cheekbones], Hyaluronic Acid and Urea - all of which are perfect for skin hydration), it improved my skin soooo much. Every time I apply this, my skin immediately brightens and get a healthy glow (which lasts for hours!).

I am now half way through my second bottle and do not intend to stop using it.

I recommend this product to everyone, BUT because it contains Citric Acid, Lactic Acid and Benzyl Alcohol, I recommend patch testing it before first use (as you should do with every new product you use!).

I used this caffeine solution for a few weeks but didn't see a huge difference, maybe I didn't have enough puffiness to really see a difference but it definitely didn't help with my dark circles. Have you ever had puffy eyes after a good cry the night before? I was really hoping this product would save me from that but alas, not a miracle in a bottle.
