This emollient moisturizer for dry skin contains an unusual ingredient: Euglena gracilis extract, which is a single-cell, chlorophyll-based microorganism normally found in water.
One study showed that a component isolated from this organism improved dry skin when fed to mice whose skin had been forcibly irritated with another substance (Source: The Journal of Veterinary and Medical Science, June 2010, pages 755–763). That's intriguing, but doesn't tell you if this ingredient would be helpful when applied topically, not to mention it won't remain stable during use because of this moisturizer's jar packaging (see More Info for details).
Although there are some good ingredients in this moisturizer, it's exceedingly overpriced for what you get, and contains enough fragrant bitter orange oil to pose a risk of irritation. Also on hand are numerous fragrant ingredients that research has shown to be irritating, which is one more reason fragrance-free is the best way to go for healthier, younger-looking skin (yet Decleor's luxury spa élan means fragrance is deep in this brand's DNA). See More Info to learn why daily use of highly fragrant products is a problem for skin.
- Contains some helpful emollient ingredients for dry skin.
- Lacks state-of-the-art anti-aging ingredients to improve wrinkles and firm skin.
- Overly fragrant formula puts skin at risk of pro-aging irritation.
- Jar packaging won't keep the most important ingredients stable during use.
Why Jar Packaging is a Problem:
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).
Why Fragrant Products Are a Problem:
Daily use of products that contain a high amount of fragrance, whether the fragrant ingredients are synthetic or natural, causes chronic irritation that can damage healthy collagen production, lead to or worsen dryness, and impair your skin's ability to heal. Fragrance-free is the best way to go for all skin types. If fragrance in your skin-care products is important to you, it should be a very low amount to minimize the risk to your skin (Sources: Inflammation Research, December 2008, pages 558–563; Skin Pharmacology and Physiology, June 2008, pages 124–135, and November-December 2000, pages 358–371; Journal of Investigative Dermatology, April 2008, pages 15–19; Journal of Cosmetic Dermatology, March 2008, pages 78–82; Mechanisms of Ageing and Development, January 2007, pages 92–105; and British Journal of Dermatology, December 2005, pages S13–S22).
