I was sceptical after reading the bottle, but it really does work. Fine lines vanish.

Great Product
Purchased

My skin is dehydrated at the moment and it's starting to show some lines. This Concentrate is helping me moisturise my skin very efficiently. I couldn't say that it removed my lines (yet!), but it drastically improve the elasticity and texture of my skin. It looks better and fuller.

Couldn't tell a difference in lines

I'm 31 and starting to get some smile lines around my eyes. I was happy to get this sample and I used it every night until it ran out. It felt soothing and nice around my eyes, but I didn't really notice a difference in the appearance of lines. It did feel nice and warm going on though, so I'm sure it was doing something -- maybe preventative for further development of line, but I couldn't really tell. Maybe if I'd used it longer.

Worked wonders!

Although the directions indicate not to apply around area, I read them a little too late and wound up doing just that. I did notice that after just 2-3 days the difference in the fine lines I get underneath my eyes were less noticeable.

Love this product!
Sampled

I just turned 40 and all of a sudden am super conscious about all the little lines and wrinkles I am getting under my eyes! I was so excited to get this sample in my box and after making the sample stretch as LONG as I could, I am going to have to break down and order some! It is a little on the expensive side but I was really pleased with the results from the sample and felt like the little lines disappeared. I really love Kiehl's brand (which I had never used prior to joining Birchbox).

Amazing

I have been using this on my brow wrinkle (the frown one) and it works. It has reduced this line a lot and it was pretty deep. Also, been using on my crow's feet and it diminishes those lines too. Definitely a purchase in my future. Love Kiehl's anyway.
