This is a pricey product yet it goes a long way. it encourages you to have a regular facial cleansing routine then add 4-5 drops to smooth all over your face and neck. Believe me. a little goes a long way. It helps to renew your skin and to have a good night's sleep while it works. it's a great beauty tip to have.

I'm a HUGE Kiehl's fan. I use this product along with UFC cleanser, toner & cleam and avocado eye cream. I've never tried oil based serum before but since I have very dry skin I think I find more moisturizing. I only need couple of drops to cover all of my face & neck so it lasts long time.

I only use a 1-2 drops at night and it make my skin smoother, softer, moist and even glow on the next day morning. Also it smell good, long-lasting and absorbs fast on the skin. Definitely worth a try!!

I really like this! I ordered some shampoo online and got a free sample of this. I love the way it makes my skin look on application. Very glowing and hydrated. $50 isn't out of line for a serum and I think it's worth it for this product. I actually like it better than some serums I've tried that are more expensive. I would purchase this.

I found it made my skin itch. I have heard it is great but not for my skin. It is also very pricey!!!

Another great product from Kiehls. I got a free sample of this product with an order I made. It has a great, relaxing scent, feels very light and leaves my skin "glowing". As with most products from Kiehl's the price is a bit high so I'm not sure if I'll be purchasing. If you can afford to treat yourself - I highly recommend this product!!

I got a sample of this from Kiehl's.

I really liked how light this product was. I have combo skin so I was wary of putting oil on my face but it sank right in and didn't feel oily at all. I mainly concentrate this on my cheeks because that's where I tend to be drier and when I wake up in the morning they feel so supple and soft. The smell is so nice too, the lavender is perfect for night time.

The only thing I don't like about it is the price. I'm currently trying out some other alternatives for my night time moisturizer/serum.

Another little gem from Kiehl's that I love.
If you have dry patches, want something light for night time or added moisture, then this is the product for you.
Although it's an oil, it absorbs sooo quickly! Even though it's advised to use 2-3 drops, I use about 1/4 of the pump because I love the feeling of the oil on my skin.
This is amazing to use, especially in the winter time when skin tends to get dry and parched easily.
Mine lasted a very long time, however, due to the essential oils being exposed to the air, the lavender smell changed slightly overtime. Not really a big deal but I don't get that relaxing aroma after a few months.

I was a little worried about trying this as my skin is so sensitive yet I'm prone to breakouts.I tried just one drop and was surprised and how far that it goes!It absorbs so quickly and is very lightweight my skin feels so smooth like velvet.The key ingredient is evening primrose which is rich in omega-6 and essential fatty acids and very effective in skin repair.

The smell is so heavenly I love it its so calming and relaxing.It is expensive but worth it!My skin is improving and feels so healthy and smooth Ive been using it for a week now in the evenings after cleansing my face and there is dramatic changes.I highly recommend this product.

I've been using this new product from Kiehl's for about 2 weeks and it is AMAZING! I've got smaller pores, better tone and a glow to my bare skin. It's got a light natural lavender scent that helps me relax for sleep after a long, tough day. Great stuff - I doubted it alot, but I'm a convert now!
