The best Vitamin C serum
I have tried a few different Vitamin C serums and this is by far the best, it absorbs really quickly, smooths my skin and it feels lovely. Great to use under spf and make-up. Highly recommend.

Impossible to absorb
Disappointed. Although the texture of the cream is very velvety and nice to apply...this eventually does not get absorbed by your skin and leaves your face in a layer of shiny oil that you can then need to wipe out. I discovered it's highly based on silicone so I guess that's the problem.

Part of my daily routine now!
This is one of the first products I tried from Kiehl’s, I loved it from the beginning and now I am ordering my second. I have dry skin and it didn’t dry it in fact it nurtured it and smoothed it out. I’m in my early 40’s and I can say it is making a difference in my fine lines care routine and also in keeping the skin clean of any eruptions.

My holy grail product
I’ve tried ALOT of skincare over the years and this is my holy grail product that I continue to re-purchase everytime I’m out. Put a bit on at night and by morning my fine lines are noticeably gone! They come back over time but I think this product is keeping them at bay from getting any worse. Lovely feeling product too.

Soft and nourished
I have been using this cream for over a year and it definitely feels rich and absorbent against my skin. My skin feels smoother and softer and well nourished.
