Key Ingredients
Vitamin C

Pure Vitamin C

Rated 5 out of 5 by from Wonderful ! Totally in love with it ! This is the most lovely product that I have used ! I will use it for my whole life . I love the texture , the smell and the effects over all. It works great on my skin , left a good feeling on it . I use it 2 times a day and it absolutely has changed my skin , it's soft like a baby skin . The price is unconsidered with the effects . Definitely worth the price and definitely is the best product followed by Ultra Facial Cream . Thank you Kiehl's . I love all the products !

Rated 1 out of 5 by from Will not repurchase I really should’ve tried a sample of this first. It has a silicone feeling on application and is hard to apply. It has no brightening effect whatsoever, in fact it’s so matte it makes me look worse. I appreciate these serums need to be used consistently for a long period of time to see any effect but this is joyless to use. Plus it’s expensive.

Rated 5 out of 5 by from Did you get botox!!! I used Too much of sample of this product. Its a bit deceiving as it looks like a cream but its consistency is more oily- going a long way. Because i used too much by how it came out, i waited to go to bed- not wanting to stain my pillow. At work the next day my coworker made me “ wrinkle my forehead “ to prove i hadnt received botox. The effects of this product were so good. I ordered it and am using it now. I still use it generously and let it sit for 1-2 hours before going to bed. I have dry skin& am in my 50’s and need it generously. Love the warming sensation when putting it on. It a ts like a mask that you dont wash off. It will be completely absorbed in the morning.

Rated 1 out of 5 by from Causes breakouts I rarely write reviews but after using this product I felt it necessary as this product was such a waste of money. I never have breakouts or get spots but after using this serum I had several breakouts & spots which were very irritated & inflamed. I really liked how the serum felt and think it instantly smooths lines, only temporarily, and it feels good on the skin during application. However, after about one week of using this product, I begun to notice breakouts happening in places where this product was applied. I stopped using the product for a while and as soon as I used it again after a break of 2 weeks I had the same breakouts again. I will not use this product anymore, nor will I recommend it to anyone. Steer clear of it.

Rated 5 out of 5 by from Noticeable Difference This is the first skincare product where i have actually seen a difference in my skin after using. The product is quite a unique texture and i did get the warming sensation it mentions on this page, but after a few days I had a comment from a colleague and i actually skipped foundation.. my skin just looks a lot less dull and a lot more even, and my fine line on my forehead has really noticeably improved!! very happy with this plus the aqua gel suncream that i also bought

Rated 5 out of 5 by from amazing! I honestly cant live without this stuff! for years I've tried everything and spent so much money on skincare and this is the only one I see results with. I have a deep wrinkle in the middle between my eyes and this literally smooths it out so much and people comment on how nice my skin is. I dont wear foundation anymore because I dont need too. if this stuff ever stopped, I dont know what I'd do!

Rated 3 out of 5 by from Acne scars Young black woman with hyperpigmentation: I bought this because it contains vitamin C, which I was told (by the salesperson) would lighten my acne scars, even though that's not how it is marketed. Having used it for a month now, I can say that whilst my skin definitely looks brighter overall, it hasn't done much for my scars.

Rated 5 out of 5 by from Great face serum! Tried a sample and then switched to this from the Age Defender serum. Much more effective. Really kind of revealed the underlying and fresh skin. I’m apply twice a day followed by Facial Fuel over it. Only been using for a couple of weeks now but very impressed so far. Best Kiehls product that I’ve used to date.
