Powerful-Strength Line-Reducing Concentrate Serum $140 Value

If you are looking for that one product that is a must....this is it. I used many different skin care products in the past and in an effort to slimline the morning process, I began eliminating one product at a time to see which one was most effective. A week after Kiehls, Vit. C was eliminated, I saw a difference. This product does what it says it will. Fine lines...gone, even skin tone...done, smooth texture...there. I make sure I NEVER run out

I was looking for a new vitamin C serum when I finished my Drunk Elephant CFirma and Sunday Riley CEO. I read many great reviews about this concentrate so I gave it a go. This product has a great unique texture that the other 2 products I mentioned don't have. It glides on very smooth and feels almost like a primer. I use and oil on top of this and my daily moisturizer. Products layer beautifully on top of this concentrate. I've used this for about 3 weeks now so I have not seen long term results yet (vitamin C is a slow and steady type of a treatment) if this gives me the same long term results as the Drunk Elephant C Firma I will be gladly switching. Just for reference - I have normal to oily skin and I am 35.

This is wonderful cream. I use it in the morning and at night. I have been using it for several years and buy it in the largest bottle it is available in. It makes my skin feel tingly and smooth. I think it has made a difference in the appearance of fine lines. I use a lot of Kiehl's products, and this is one of my favorites.
