Glycerin 

Glycerin is a by-product of soap manufacturing and is a clear, syrupy liquid, usually derived from vegetable oil and obtained by adding alkalies to fats and fixed oils. It is a solvent humectant and emollient in many skin care products, as it absorbs moisture from the air and thereby helps products retain their moisture. It improves the spreadability of products and has definite skin moisturizing benefits.

PRO-puh'-leen GLY-kaul

Propylene Glycol is a common moisture carrying ingredient in skin care. It acts as a humectant by absorbing water from the air. It penetrates the upper layers of the skin well and leaves a nice feel.

Rated 5 out of 5 by My Go To Serum I got this as a sample when I was purchasing eye cream. This serum is WOW! I used it for 4 nights and saw a huge difference in my skin - had blemishes that were beginning to diminish. I was astounded at how fast this stuff works and delighted. This is my GO TO serum....Love, Love, Love it! 08/02/15
Rated 5 out of 5 by I noticed a difference after the first use! I've had very oily skin for most of my life - that being said, over the 6 months, I have noticed that I've begun to see some signs of aging - particularly, I now have some fine lines showing on my forward. I bought this product last week and noticed that the lines of my forward had all but disappeared after the first use. I've now used it 3 times and the lines that were visible last week when looking into the mirror from a regular distance are now so faint that you can only see them when I move my face a few inches from the mirror. How this could already be working, I have no idea.... But it is and it has! I can't say that it would work for everyone, but I'm seriously impressed and how quickly I've seen a difference. 24/01/15
Rated 5 out of 5 by Love this product! I purchased this product approximately 3 months ago on a recommendation from my daughters. They have used Kiehl's products for over 2 years and encouraged me to try this concentrate. I love it! My skin is softer, healthier-looking and I have had several comments recently of 'do you ever age'? I think I'm hooked! 25/09/14
Rated 5 out of 5 by I absolutely love it! I just started using this product a week ago, and already notice an improved appearance in my skin. I love how soft and smooth my skin feels. 21/08/14
Rated 4 out of 5 by After trying a sample of this product I bought a big bottle of it right away. It was a lot more expensive than I was expecting but it left my skin feeling really smooth. I'm not sure how well it works on wrinkles and fine lines but the texture feels like my favorite make-up primers and seems to have a similar effect. Although it absorbs into my skin it leaves a bit of a greasy film and leaves my face a little shiny (not in the glowing, dewy way.) I don't mind the greasy residue I leave behind though because my skin no longer feels dull or dry after using it. 12/08/14
Rated 5 out of 5 by Awesomeness! This serum is a must have! I have red cheeks with some acne scars that are fading and my skin tone is starting to smooth out. I love love love this!! 10/08/14
Rated 5 out of 5 by Love it! I tried this concentrate about a year ago and right away, I loved the tingling sensation of the vitamin C. My skin feels soft and my wrinlkes do look smaller and less defined. Can't go one day without it! 20/05/14
Rated 5 out of 5 by Addictive! This stuff is totally addictive. I'm not sure why but I ignore all others and only want to use this. Makes my skin feel incredible that my entire body is begging for me to use it. If it cost less, I would slather myself in it. 11/02/13
