I have very sensitive skin and it burns. So I had to wash it right off unfortunately.

Good Product
Sampled

This is a great lightweight serum to help combat wrinkles and aging skin. It feels nice when you put it on, but for me it isn't necessarily moisturizing, so I add a little moisturizer on top. overall not a bad product

nice vitamin c serum
Sampled

i have been using vitamin c serums for years to keep dark spots from surfacing for as long as possible. this felt nice. of course with any skin care, a sample can only allow you to see minimal effects on the skin. definite possibility for a future purchase.

Just like most moisturizers/serums, I didn't see or feel a difference in my skin.

Too Soon to Tell! Sample Size
Sampled

I loved the feel of my skin immediately after applying this cream. I also felt some firming after applying but since it is only a sample size I think its too soon to tell if it truly lightens fine lines. The price for the full size is a bit pricey to chance the effectiveness. Possibly if I can find it at a discount price I would consider purchasing.

Well i am trying this product. So i am waiting to see results. I like all of Kiehl's products so i am hoping i see some improvement. The full size version is expensive so not sure if i will purchase.

Old Skin Needs This

Kiehl's products are consistently good and I think I will like this after a time. There is no instant cure for aging
