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.

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 1 out of 5 by Would not spend the money again!! I purchased this product after reading the amazing reviews both online and in a magazine or two. I was extremely hopeful and thought it would be great. i was NOT expecting any sort of "miracle" but i did think i would notice some form of improvement. First off the texture and look of the serum is strange. Initially I thought the product had gone bad but after researching, I found that it was correct in colour and texture. I have used the product now twice daily for 60 days and have seen no visible signs of improvement in lines, skin texture, colour, etc. Truthfully considering the price and the results i would definitely not purchase this product again and would advise anyone else to do the same. 27/10/15

Rated 5 out of 5 by BEST PREVENTION SERUM I love this product as both a treatment and a preventative measure. The texture is really nice, not too watery or thick, but rather a light cream that just melts as you apply it. I have been using the product for over a year, and have noticed an improvement in my skin texture, and especially a reduction in the appearance of fine lines. And best of all, no new lines.... which is why I just can't get enough! The name of the product was a bit intimidating for me as I am only in my late twenties, but it works very well, and now it's an absolute must have for me! Highly recommend this product for both treatment and prevention! 13/07/15

Rated 5 out of 5 by Excellent serum I have been using this serum for years and I absolutely love it. I hate the feeling of anything on my skin and this is so light that it feels like nothing at all but the effects are definitely noticeable. 12/07/15
