Tested on animals:Yes
This fragrance-free moisturizer from Kiehl's is a clear example of the formulary influence parent company L'Oreal has had on the brand. The core ingredients in Powerful Wrinkle Reducing Cream are identical to those in several Lancome moisturizers, including those that cost a lot more. Does that mean this Kiehl's moisturizer is an anti-aging beauty bargain? Sadly, no. L'Oreal's attempts at anti-aging skin care has been far more hype than substance, and this not-so-powerful cream is one more example of a product that's mostly just hype.
What we have here is a basic moisturizer for normal to dry skin. The tiny amount of plant extracts, calcium, and copper are minimally helpful for skin, especially given that this product is packaged in a jar (see More Info to find out why you should never buy an anti-aging moisturizer packaged in this manner).
Along with being just a moisturizer with minimal anti-aging power, this product is incapable of minimizing pores as claimed. If anything, the emollient ingredients in this cream can make pores become more enlarged and potentially clog pores (and when pores become clogged, they don't get smaller!).
What about the copper PCA and calcium PCA? There isn't a shred of published research proving either ingredient has any impact on skin's elasticity, firmness, or any other aspect of aging. And even if there was some solid research showing the way, we doubt the teeny-tiny amounts this moisturizer contains would be enough to bring about a noticeable change in skin. What you'll see from this moisturizer is smoother, softer skin, that's it. Like any emollient moisturizer, when applied over dry skin wrinkles will look less apparent—but for true anti-aging "power" your skin deserves more than what this can provide!
- Moisturizes dry skin without feeling greasy.
- Jar packaging won't help keep the key ingredients stable during use.
- A standard moisturizer formula that's not as powerful or wrinkle-reducing as its name states.
- The emollient ingredients this contains cannot minimize pores as claimed.
- There's no published research showing copper or calcium improve skin's elasticity.
The fact that this wrinkle cream is packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, vitamins, antioxidants, and 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 are unsanitary because you're dipping your fingers into them with each use, adding bacteria which further deteriorate the beneficial 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; Beautypackaging.com, and www.beautypackaging.com/articles/2007/03/airless-packaging.php).
