The green tea and its history, from Asia to Europe.
The tea plant is a perennial shrub belonging to the Theaceae family. It can grow up to 15 meters in height, but in cultivation, it is pruned to a height of 1 to 3 meters to facilitate harvesting. Originating from China, specifically from the region of Yúnnán, it is grown in areas with mild climates and high rainfall. Its botanical name Camellia sinensis literally translates to "Chinese camellia".
According to legend, green tea was discovered about 5,000 years ago in China by Emperor Shennong. The invigorating and refreshing effects, as well as the medicinal properties of this plant, have contributed to its increasingly widespread use, particularly among Buddhist monks and the Chinese upper class.
It wasn't until the early 1600s that tea began to be imported into Europe via the Dutch East India Company, which held a monopoly on European trade with Asia. Due to its high price, it was unaffordable for the lower classes and only the upper classes consumed it. Pharmacists (apothecaries) sold it in their shops as a medicinal plant.
What is green tea hydrosol?
Also known as green tea leaf extract, this hydrosol appears as a mobile liquid ranging from colorless to pale yellow, with a honey-like scent. It is produced through a process called hydrodistillation, which involves treating green tea leaves with steam in a still. Two distinct fractions are then collected: the essential oil and the hydrosol.
Derived from the same plant, these two compounds have similar properties, but the hydrosol is less concentrated in active species, as the aromatic essences are present in smaller quantities. Therefore, it can be used without contraindications by children and pregnant women, unlike the essential oil.
The virtues of green tea hydrosol in cosmetics.
green tea hydrosolis recognized for three main functions:
Its decongesting action.
The linalool and benzaldehyde it contains stimulate microcirculation, which helps to decongest the eye contour area and thus reduce the appearance of dark circles. Its toning action also allows it to revive dull skin.
Its astringent action.
Green tea hydrosol is often recommended for oily skin, as its purifying properties help to tighten pores and refine skin texture. It also gently restores the skin's pH and sanitizes the skin without causing irritation.
Its antioxidant action.
The skin is daily assaulted by free radicals, reactive oxygen species naturally produced by the body. This phenomenon is normal, but stress, pollution, sun exposure, smoking, and of course, an unbalanced diet, promote their excessive production. The skin loses its elasticity and suppleness. Wrinkles form on the surface. Green tea hydrosol contains anti-radical compounds that stabilize and neutralize them. It is thus antioxidant and helps to fight against premature skin aging.
The antioxidant botanical mist with green tea from Typology is a portable treatment to be applied to the face at any time of the day. It revives the complexion's radiance and protects the skin.
