Super ingredient taurine is skin care’s version of a wake-up call—so if your skin looks dull and tired, then it’s time to get acquainted. And honestly, whose skin doesn’t look dull and tired sometimes? Between dehydration, pollution, late nights, you name it, life’s daily stressors add up. Enter taurine, a key ingredient in Clinique iD Active Cartridge Concentrate for Fatigue. It helps to boost circulation and instantly gives skin an energized radiance. Let’s go.

Energy drink darling
Taurine is an amino acid that’s naturally produced by your body and found in your brain, eyes, heart and muscles. It’s also a common ingredient in energy drinks and touted for its assistance in (among other things) maintaining hydration and balancing electrolytes. Although the name “taurine” is derived from the Latin word taurus, which means “bull” or “ox,” taurine has nothing to do with actual bulls. Or oxen.

Better than a shot
In skin care, legendary taurine is a powerful form of anti-fatigue. When applied topically, taurine re-energizes skin to minimize the signs of fatigue. How? It boosts circulation and inter-cellular energy—helping with rehydration; so your skin instantly looks and feels more awake. Not dull. Not listless. Not tired. And with continued use, taurine can give you real improved radiance with a renewed glow, sort of like you’ve been unfazed by the daily grind. What stress?

Turn on the radiance
If you look as tired as you feel, then taurine is for you. If you look tired but you feel great—one of life’s cruel ironies—then taurine is for you too.
