Glucono-what?  It might be hard to say, but boy...does your skin love it!  The molecules that come together to form gluconolactone are naturally attracted to water. When this naturally occurring ingredient is applied to the skin, these "water hungry" molecules pull moisture out of the air and allow it to be absorbed by the skin. By drawing water droplets from the air in this way, gluconolactone helps to soften and soothe dry skin and replenish lost moisture. In addition, gluconolactone forms a barrier on the skin, preventing moisture already present in the tissue from evaporating. Gluconolactone provided up to 50% protection against UV radiation and UV radiation-induced elastin promotor activation.  This is but one of the top powerful anti-aging ingredients found in our ecologica Eye Protective Cream.
