This is a decent, somewhat basic mask for dry skin that contains a good amount of skin-repairing glycerin plus urea, an ingredient that definitely helps support Kiehl's claim of this mask providing long-lasting hydration. What's doing very little, if anything, to hydrate skin are the "glacial proteins and desert plant leaves" boasted about in the claims because these plus the hyaluronic acid are present in very small amounts.

Assuming that the plant extracts were used in great enough concentration to benefit skin, they wouldn't hydrate; rather, they'd function as antioxidants—which is where this mask's jar packaging comes into play. Antioxidants break down with repeated exposure to light and air, so this type of packaging is the wrong way to go if the goal is keeping those good-for-skin ingredients stable during use. See More Info for the full scoop on the problems jar packaging presents.

In better packaging, this fragrance-free mask would be worth trying, and with a few formulary additions, it would be a brilliant option for dry skin.

  • Contains proven hydrating ingredients for dry skin.
  • Leaves skin feeling soft, smooth, and replenished.
  • Fragrance-free.
  • Jar packaging won't keep light- and air-sensitive ingredients stable once opened.
  • Contains a teeny-tiny, likely inconsequential amount of the called-out glacial protein and desert leaf ingredients.
  • A basic formula that's not as exciting as it could've been.
More Info:

More Info: The fact that this product is packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, vitamins, antioxidants, and most other state-of-the-art ingredients break down in the presence of air, so once a jar is opened and lets the air in these important ingredients begin to deteriorate. Jars also present a hygiene issue because even if you wash your hands or use a spatula to remove the product, you're introducing bacteria that causes further breakdown of key ingredients (Sources: Free Radical Biology and Medicine, September 2007, pages 818-829; Ageing Research Reviews, December 2007, pages 271-288; Dermatologic Therapy, September-October 2007, pages 314-321; International Journal of Pharmaceutics, June 12, 2005, pages 197-203; Pharmaceutical Development and Technology, January 2002, pages 1-32; International Society for Horticultural Science, www.actahort.org/members/showpdf?booknrarnr=778_5; and www.beautypackaging.com/articles/2007/03/airless-packaging.php).

Brand Overview

Kiehl's At-A-Glance

Kiehl’s has been around for quite some time, with its origins in a New York City-based pharmacy established in 1851. The brand is perhaps best known for its apothecary-style packaging and its best-selling (and celebrity favorite) Lip Balm #1.

Though the brand claims its products are made with the finest naturally-derived ingredients, most of its formulations include synthetically-produced ingredients as well. Like most skincare companies the line contains both good and not-so-great offerings; Kiehl’s main misstep is that many of its products contain fragrance ingredients that could irritate skin, particularly sensitive skin.

Note: Kiehl's is categorized as a brand that tests on animals because its products are sold in China. Although Kiehl's does not conduct animal testing for its products sold elsewhere, the Chinese government requires imported cosmetics be tested on animals, so foreign companies retailing there must comply. This requirement is why some brands state that they don’t test on animals “unless required by law.” Animal rights organizations consider cosmetic companies retailed in China to be brands that test on animals, and so does the Beautypedia Research Team.
