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 4 out of 5 by Good product but Do not like wasteful delivery method. Suggest tube or jar. I paid full price for this product, despite that I did once get a free sample. The review posts incorrectly. 25/01/16
Rated 5 out of 5 by best product ever This is the best product I have ever used!!!!! I am pregnant and have been struggling with chloasma. Since the first time I tried it I saw improvement and if I miss a day using this it comes back. IT has been a life saver. I can also see a drastic change in my "crows feet". 22/01/16
Rated 1 out of 5 by Will Give More Time I have been using the Line-Reducing Concentrate along withSuper Multi-Corrective Cream in the daytime and Midnight Recovery at night for a month. To now I haven't seen any improvements. The lines and wrinkles in my face seem to be the same as they were. I do give products a few months to work and will continue using them. I am in my early 60's and perhaps my skin is too far gone for anything to improve it. 06/12/15

Rated 5 out of 5 by amazing This is my first time purchasing Kiehl products and I am loving them. I have hyper sensitive skin and was very hesitant, now I only wish that I had tried them sooner. Thank you 20/11/15
Rated 5 out of 5 by Love love love! I've been using this product for 5+ years & receive compliments on the condition of my 60yr old skin. After applying, my skin feels soft and moisturied. Highly recommend! 14/11/15
Rated 5 out of 5 by Good stuff I have been using this serum in the morning and night for over a month and I love the way my skin looks and feels. This serum gives my skin a beautiful glow and I see an improvement in my skin texture. I like the fact that this has Vitamin C in it and will be ordering this again when I run out. I must say this is not very hydrating so I do layer this under a moisturizer. I have oily/combo dry skin and I find that I do need a moisturizer over this product. I dispense two pumps and it is just enough product to cover my face I then follow with sunblock in the day and moisturizer at night. The 1.7 ounce bottle should last me a while with just two pumps twice a day I hope. I am very happy with this product so far. 13/11/15
Rated 1 out of 5 by Did I get a lemon? The consistency of the bottle I purchased was really strange. It seemed like the ingredients were separating and it looked like curdled milk. I just finished the whole bottle, but when I looked inside there were thick clumps all around the inside of the bottle. Not sure what happened with the contents of mine, but something definitely happened to have made it separate. Trying to see if I should bother purchasing a new bottle to see if it's the same with all or I just spent $60 on a defective bottle. 13/11/15
