Kiehl's is Bae
Sampled

I LOVE Kiehl's products. This is my favorite so far. Boy does it moisturize and smooth out lines. I'm not sure the effects are lasting, but it definitely makes lines look smoother when you apply it. I pout it between my brows and along my smile lines under my makeup and was happy with the results. It improves the look of your skin right away. A larger size would provide more data as to whether it has lasting effects on lines.

Great on my skin

Highly recommend this serum. After I do my nightly skin regime I put this on last and I wake up my skin is still glowing like a new baby.

Felt nice

I used all my sample up within the week while it felt really nice and made my skin feel hydrated I don't think it did anything for my fine lines.

Nice

So far I like it. It's still too soon to see if it actually does what it's suppose to. It's light n fresh not oily smell is not to strong

Love it!

This product is non-greasy and leaves my face feeling very soft. I haven't noticed any brightening to my face, but I have noticed that my skin is more even-toned after use.

Couldn't tell a difference

I could not tell a difference with this. I am not sure if it is something you need to use long term but I did not see anything.

runny
Sampled

I didn't care for this product. I felt like it was runny and I didn't see any results. I wouldn't buy a full size of this product.
