Kiehl's Rare Earth Deep Pore Cleansing Masque is a good, though not great, option for those with combination to oily skin looking for a clay mask to help absorb oil. The reason it doesn't rate higher is because of its packaging and the fact that it simply can't live up to all its claims.
First, the good: This mask is fragrance free and contains no potentially irritating essential oils (a welcome change considering many oil-absorbing masks include these). The formula includes tried-and-true mattifying ingredients like clay and corn starch, along with anti-irritants like oatmeal and allantoin to soothe skin.
The issue with this mask is largely in its claims: Kiehl's says it can purify skin and draw out toxins that clog pores. The fact is that your skin simply doesn't accumulate toxins, and what toxins your body might contain can't be drawn out through your pores (see More Info for details).
The other problem is this mask's jar packaging. Although Kiehl's doesn't make any anti-aging claims, there's still the potential to introduce bacteria into the mask, which stresses the preservative system and is just not hygienic.
Though this isn't a bad option at all, there are definitely better products available, which you can find on our list of Best Face Masks.
Why Beauty Products Can't Detoxify Your Skin: Despite the claims of many a cosmetics company, you cannot "detox" your skin. In fact, brands making this claim never specify exactly which substances or toxins their products are supposed to eliminate, which makes sense, because your skin does not store toxins.
Toxins are classified as endogenous (produced by the body) or exogenous (introduced into the body, usually through ingestion or absorption). They can be produced by plants, animals, insects, reptiles (think snake venom or bee stings), or other organisms. They also can be inorganic, such as heavy metals like lead, arsenic, and others.
Toxins cannot leave your body through the pores on the skin, whether via sweat or other means; rather, they are filtered, broken down, and removed by the kidneys and liver. In some cases, medical treatment is needed to remove toxins from the body.
Regardless of the skin concern you're battling, "toxins" are not to blame—instead, stick to what the research says really works, and ignore the fantasy claims about "detoxifying" cosmetic products spa treatments.
Jar Packaging & Basic Skincare Products: While jar packaging is never ideal, the more basic moisturizing or absorbing ingredients (such as petrolatum and clay) are less susceptible to the stability issues associated with exposure to light and air.
Factors such as an exceptional formula may help move a moisturizer up to a higher rating, despite being packaged in a jar, but will never move it up to our highest rating
Jars are still unsanitary (more so for water-based formulas) because you're dipping your fingers into them with each use, adding bacteria (this is true whether you use your fingers or a spatula). If you prefer a bottle or tube, not to worry, there are plenty to choose from in the Best Products section!
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.
