This cream-gel moisturizer contains fractions (extracts) of fruits and vegetables that function as antioxidants, but most of them aren’t present in amounts your skin will notice—even if they were, the poor choice of jar packaging means they won’t remain stable for long. See More Info to find out why jar packaging for products like this is always a bad idea.
The goal of this moisturizer for normal to combination skin is to reduce signs of “fatigue” before they become signs of aging, but one doesn’t cause the other. Yes, we tend to look “older” when we’re fatigued, but most signs of aging come from cumulative sun exposure, smoking, an unhealthy diet, menopause, genetics, and gravity; it has nothing to do with being fatigued. Being fatigued simply exaggerates what’s already there, but that’s not the same as fatigue causing signs of aging; getting a good night’s sleep and exercise is what you need to combat fatigue, not this product.
Even if there was stronger logic to the “fatigue causes signs of aging” claim, this fragranced moisturizer’s overall formula and unfortunate packaging leave much to be desired. It cannot work “non-stop,” but instead barely squeaks by, and your skin deserves more than that!
One more point, Biotherm’s claims and advertised ingredients would lead you to believe their products are all about natural formulations, and that is absolutely not the case. These products are steeped in synthetics, some that are great for skin, but also some that are definitely problematic.
- Silky, somewhat unique, cream-gel texture hydrates well.
- Jar packaging won’t keep the “fruit and vegetable fractions” stable during use.
- Contains fragrance ingredients known to cause irritation (explained in the More Info section).
The fact that it’s 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).
Irritation From Fragrance and Fragrant Oils
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).
