Love love love and more love

I have been using this product for 3 or 4 years now. Helps with fine lines. It's hard to find a vitamin c product with a pump. Ascorbic Acid (vitamin D) breaks down very fast chemically when exposed to air. So it's important that it comes in a pump. Love this products!

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.

I didn't see a difference
Sampled

I honestly didn't see a difference using this serum. I think I really need stronger acid serums in order to reveal my best skin. I'm not a fan of Kiehl's in general - I think most of their money is spent on marketing, not on the actual products themselves.

Love all Kiehl's products!
Used it before I put on my tinted moisturizer every morning! A great product to use day or night.

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.

Very Nice Product

I was very happy with this sample. The texture of this product is really nice and silky. I used it once or twice a day under my moisturizer and noticed a difference in my wrinkles.

In Love!

I have a mid size deeper wrinkle on my forehead between my eyes. I used this just on the area of deeper wrinkles. They disappear. I use it in am and pm ....concentrating directly on wrinkle/trouble spots.

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.
