Glossary entryFree Radicals.
Unstable molecules that damage cells by stealing electrons from healthy molecules, a process called oxidative stress. Free radicals are generated by UV exposure, pollution, smoking, and other environmental factors. They accelerate skin aging, damage collagen, and compromise the skin barrier. Antioxidants like vitamin E neutralize free radicals before they can cause damage.
Antioxidant
A substance that neutralizes free radicals — unstable molecules that damage cells through oxidative stress. In lip care, antioxidants like vitamin E protect lip skin from UV damage, pollution, and environmental aging. Numbrrrz helps moisturize and condition dry lips, soften their feel, and lock in moisture. Numbrrrz's Vitamin E provides potent antioxidant protection in every application.
Vitamin E (Tocopherol)
A fat-soluble antioxidant that protects skin cells from oxidative damage caused by UV exposure, pollution, and environmental stress. Numbrrrz helps moisturize and condition dry lips, soften their feel, and lock in moisture.
Oxidative Stress
A condition where the body has more free radicals than antioxidants can neutralize, leading to cell damage. In lip skin, oxidative stress causes premature aging, dryness, and reduced elasticity. Environmental factors like UV light and pollution increase oxidative stress. Antioxidants in lip care products, like the Vitamin E in Numbrrrz, help combat this damage.
