walnut extract. Can have antioxidant properties (Source: Journal of Nutrition, November 2001, pages 2837-2842). There is no research showing this to have any benefit for skin.

walnut oil. Emollient, nonfragrant plant oil. See natural moisturizing factors.

walnut-shell powder. Abrasive used in scrub products.

water. The most widely used cosmetic ingredient; it is almost always listed first on an ingredient label because it is usually the ingredient with the highest concentration. Yet, despite claims of the skin's need for hydration and the claims regarding the special type of water used, it turns out that water may not be an important ingredient for skin. Only a 10% concentration of water in the outer layer of skin is necessary for softness and pliability in this part of the epidermis (Source: Skin Pharmacology and Applied Skin Physiology, November-December 1999, pages 344-351). Studies that have compared the water content of dry skin to that of normal or oily skin don't find a statistically significant difference in moisture levels between them (Source: Journal of Cosmetic Chemistry, September/October 1993, page 249). Further, too much water in the skin can be a problem, because it can disrupt the skin's intercellular matrix, the substances that keep skin cells bonded to each other (Source: Contact Dermatitis, December 1999, pages 311-314). The most significant aspect of the skin's health is the structural organization of the intercellular lipids and the related materials that keep skin intact and prevent water loss (Sources: Trends in Cell Biology, August 2002, page 355; and Journal of the American Academy of Dermatology, August 2002, pages 198-208). See natural moisturizing factors, and oxygenated water.

Water-based Liquid Foundations. Water-based liquid foundations provide light to medium coverage. Most come in a dewy finish. The emollient content in these foundation allows other makeup like eyeshadows and blusher to be blended easily later on.

water-binding agent. Wide range of ingredients that help skin retain water (moisture). Glycerin is one of the more typical and effective water-binding agents used in cosmetics. One group of water-binding agents can mimic the skins actual structure and can be of benefit in a formulation; these include ceramide, lecithin, glycerin, polysaccharides, hyaluronic acid, sodium hyaluronate, mucopolysaccharides, sodium PCA, collagen, elastin, proteins, amino acids, cholesterol, glucose, sucrose, fructose, glycogen, phospholipids, glycosphingolipids, and glycosaminoglycans. No single one of these is preferred over the other because even though they are all effective, none of them can permanently change the actual structure of skin. See natural moisturizing factors.

watercress extract. There is some evidence that when consumed in the diet, watercress has some anticancer and antioxidant properties (Sources: Journal of Nutrition, March 1999, pages 768S-774S; and Food Chemistry Toxicology, February-March 1999, pages 95-103). Whether these properties translate to skin when the extract is applied topically is unknown. However, because watercress is a source of mustard oil, it can be a skin irritant.

waterproof eyeliner.  Keep the liner light and even. You can use a cotton bud to smudge a little liner and achieve an exotic look. The liner can be applied with a lighter line on the inner eye and thickening as it goes outward to offset the effect of close-set eyes. The right application of eye liner makeup can create the effect of more expressive eyes. Liquid eyeliners that are alcohol based are waterproof.

waterproof foundation.  Sometimes the extra coverage of a foundation may not really last for a long time. This is especially possible in summer due to the humidity and high temperatures that may prevail throughout the day.  During these days waterproof foundation is of great help to your skin.
Waterproof foundation comes in different shades to suit a variety of skin types.

water proof cosmetics. (to include: water proof eye liner, water proof eyeliner, waterproof cosmetics, waterproof eye liner, waterproof eyeliner, waterproof eyeliner  , waterproof liquid eyeliner , waterproof liquid eyeliner, waterproof make up , waterproof non toxic cosmetic foundation, best waterproof eyeliner) Does not come off in the water.

water proof makeup.  A makeup that is impervious or unaffected by water in its liquid form.

waterproof mascara.  Makeup that is used to darken and thicken the eye lashes and is water-resistant.

wheat germ glycerides. Used as emollient and thickening agents in cosmetics. See glyceryl ester, and natural moisturizing factors.

wheat germ oil. Emollient plant oil similar to all nonfragrant plant oils. See natural moisturizing factors.

wheat protein. See natural moisturizing factors, and protein.

whey. Milk contains two primary proteins, casein and whey. When cheese is produced the more liquid components, whey and casein, are separated from the cheese. When eaten or taken in oral supplements whey protein can have significant antioxidant properties (Source: Journal of Dairy Science, December 2001, pages 2577-2583) as well as anticancer properties (Source: Anticancer Research, November-December 2000, pages 4785-4792) because it generates the production of glutathione in the body, which is a significant antioxidant. Whether or not any of those benefits translate to skin is unknown. In skin care products it is most likely a good water-binding agent.

white camellia extract or oil. Used as a fragrance in cosmetics; it may be a skin sensitizer.

white nettle. Contains components that can have both anti-irritant as well as inflammatory properties (Source:

white oak bark extract. See oak root extract.

white tea leaf extract. The minimally processed buds and leaves of green tea. There is research showing white and green teas to have the highest concentration of antioxidant properties (via their polyphenol and flavonoid content) of all teas, and several in vitro and animal studies have shown green tea and white tea to have anticancer and antimutagenic properties. However, even though tea flavonoids are effective antioxidants, it is unclear to what extent they increase the antioxidant capacity of humans, and there is no research showing what their activity means for skin. It appears that white and green tea share similar amounts of the polyphenol Epigallocatechin-3-gallate (EGCG), which is teas main antioxidant. The conclusion drawn is that white and green tea have nearly identical antioxidant activity (Source: Biochemical and Biophysical Research Communications, Volume 296, Issue 3, August 23, 2002, pages 584-588.) See green tea.

white willow. See willow bark.

wild ginger. See ginger.

wild yam extract. The roots of wild yams were used in the first commercial production of oral contraceptives, topical hormones, androgens, estrogens, progesterones, and other sex hormones. Diosgenin, a component of wild yam, is promoted as a natural precursor to dehydroepiandrosterone (DHEA). Some wild-yam products are promoted as "natural DHEA." Although diosgenin can be converted to steroidal compounds, including DHEA, in the laboratory, this chemical synthesis does not occur in the human body. So taking wild-yam extracts will not increase DHEA levels in humans (Source: Natural Medicines Comprehensive Database, There is no research showing wild yam has any effectiveness when applied topically on skin. If anything, the studies that do exist have demonstrated that topical application of wild yam has little to no effect on menopausal symptoms (Source: Climacteric, June 2001, pages 144-150). See DHEA.

willow bark. Contains salicin, a substance that when taken orally is converted by the digestive process to salicylic acid (beta hydroxy acid). The process of converting willow bark to salicylic acid requires the presence of enzymes to turn the salicin into salicylic acid. The digestive conversion process that turns salicin into saligenin, and then into salicylic acid, is complex. Further, salicin, much like salicylic acid, is stable only under acidic conditions. The likelihood that willow bark in the tiny amount used in cosmetics can mimic the effectiveness of salicylic acid is at best problematic, and in all likelihood impossible. However, willow bark may indeed have some anti-inflammatory benefits for skin because, in this form, it appears to retain more of its aspirin-like composition.

willow herb. See Epilobium angustifolium extract.

wintergreen oil. Can be very irritating and sensitizing (Source: Natural Medicines Comprehensive Database, See counter-irritant.

witch hazel. Can have potent antioxidant properties (Sources: Phytotherapy Research, June 2002, pages 364-367; and Journal of Dermatological Science, July 1995, pages 25-34) and some anti-irritant properties (Source: Skin Pharmacology and Applied Skin Physiology, March-April 2002, pages 125-132). However, according to the Consumer's Dictionary of Cosmetic Ingredients, Fifth Edition, Ruth Winter, 1995, Random House), Witch hazel can have an ethanol [alcohol] content of 70 to 80 percent. Witch hazel water contains 15% ethanol.The alcohol can be an irritant. Witch hazel also has a high tannin content (and tannin is a potent antioxidant), which can also be irritating when used repeatedly on skin, though when used for initial swelling from burns it can reduce inflammation.

wrinkle reduction.  Eliminate moderate to deep lines and creases due to aging and photodamage.
Organic Cosmetics. There are natural potions containing grape seed oil, cocoa butter, rosewater, borax, aloe Vera, and anhydrous lanolin, which keeps the skin smooth like silk. The beauty of natural productsis that it has natural oils, contains no petroleum based waxes or oil and they naturally help heal and moisturize

wormword. Herb that has antioxidant properties (Source: Journal of Agricultural Food Chemistry, November 2001, pages 5165-5170).

Wu wei zi. Also known as Schisandra chinensis, this herb can have a constricting effect and can be a skin irritant.
