This skin-lightening product contains far too many problematic ingredients to earn a recommendation. Things start off badly with alcohol as the second ingredient (which causes free-radical damage and other problems), and the only skin-lightening ingredient (ascorbyl glucoside, a form of vitamin C) of note is likely present in an amount too low for it to improve dark spots. Even if the vitamin C content were greater, the alcohol is a deal-breaker (see More Info to find out why).
Adding to the problem with alcohol mentioned above is the inclusion of several fragrance ingredients known to cause irritation; it’s almost a “who’s who” of every problematic fragrance ingredient known! See More Info to learn why daily use of highly fragranced products is bad for all skin types.
The formula contains some mineral pigments (mica and titanium dioxide) for shine and a subtle brightening effect, but this visual trick is strictly cosmetic; it cannot improve dark spots.
Last, the amount of salicylic acid is likely too low for it to function as an exfoliant—and even if it were present at a 1% concentration, this product’s pH is too high for exfoliation to occur.
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.
- High amount of alcohol causes irritation that is the opposite of anti-aging.
- Although the form of vitamin C included is good, the amount is likely too low to improve brown spots.
- The amount of salicylic acid is likely too low for it to exfoliate, and the pH is not within range for exfoliation to occur.
- Contains numerous fragrance ingredients known to cause irritation.
Alcohol in Skin-Care Products
Alcohol in skin-care products causes dryness and free-radical damage, and impairs the skin’s ability to heal. The irritation it causes damages healthy collagen production and can stimulate oil production at the base of the pore, making oily skin worse (Sources: “Skin Care—From the Inside Out and Outside In,”Tufts Daily, April 1, 2002; eMedicine Journal, May 8, 2002, volume 3, number 5, www.emedicine.com; Cutis, February 2001, pages 25–27; Contact Dermatitis, January 1996, pages 12–16; and http://pubs.niaaa.nih.gov/publications/arh27-4/277-284.htm).
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).
