vesicle:small, fuild-filled spot 5mm or 0.20 inches or smaller in diameter. Burns, chickenpox, allergic reactions, shingles (Herpes zoster) and irritation form vesicles. A bulla is a vesicle larger than 5mm or 0.20 inches in diameter.
vitamin A:comes in various forms, most prevelant in skin care is Retinyl Palmitate (INCI name). Helps improve the texture of skin, including fine lines and wrinkles.
vitamin C:Ascorbic Acid (INCI name). Powerful systemic (internal) and topical anti-oxidant, water-soluble. Must be stabilized to remain potent and effective. Used to stimulate collagen production by the skin's fibroblasts. Also used as a preservative in cosmetics in its water phase and in its fat-soluble form. When vitamin C containing products become dark, the vitamin C has been used up and is nolonger active. Certain compounds such as Magnesium L-Ascorbyl Complex offer a unique form of vitamin C - it is converted into vitamin C by the skin's metabolism once absorbed by the skin - thus giving a fresh, potent and effective vitamin C. See Nancy K Brown AloCel C for one of the most potent vitamin C products available today.
vitamin D:regulates cell turnover - the speed at which new cells are produced by the skin.
vitamin E:Tocopherol (INCI name). Fat-soluble anti-oxidant, helps protect cell membranes from oxidation (free-radical damage) by binding to lipid (fat) free-radicals and neutralizing them. Used in skin care for its anti-oxidant, emmollient and preservative properties.
vulneraries:herbs that help promote the healing of wounds by promoting cell growth and repair. Others in this category include: cayenne, comfrey, garlic, rosemary, calendula and thyme.
