Theanine Description

Theanine is an amino acid that has emollient, humectant, and soothing properties on skin. It can be lab-synthesized but also occurs naturally in green tea leaves and some types of edible mushrooms. Consumption of green tea has numerous studies supporting its benefits for overall health and vitality, and its theanine component is of strong worth for use in skin care, too.

Its low molecular weight allows it to penetrate past skin’s surface, where it works within its epidermal layers to attract and hold water, thus maintaining skin’s hydration. It also works within skin’s uppermost layers to offset factors that lead to signs of inflammation.

Theanine is used on its own in foods and caffeinated beverages to enhance flavor (it tastes of caramel which offsets the bitterness of caffeine). As such, it is considered safe for use on skin although usage levels of theanine in cosmetics haven’t been established.
