Camellia Sinensis Leaf Extract is derived from the leaves of the tea plant. Black tea, green tea, and oolong tea are all harvested from this plant.

Camellia Sinensis Leaf Extract has many benefits. It contains polyphenols, a strong antioxidant. Antioxidants help fight off free-radical molecules that damage skin cells. The antioxidants in green tea neutralize free-radicals from the sun. This gives the skin some extra UV protection, but should not replace sunscreen.

Many components of tea have anti-inflammatory properties. Polyphenols and L-theanine help soothe the skin and reduce irritation. L-theanine is an amino acid that makes up most of the amino acids found in tea leaves. The caffeine in Camellia Sinensis Leaf Extract helps calm inflamed blood vessels.

Camellia Sinensis Leaf Extract also contains Vitamin Bs, linoleic acid, magnesium, calcium, iron, and zinc.

Camellia Sinensis Leaf Extract also has antimicrobial properties.

Research has shown both drinking Camellia Sinensis Leaf Tea and applying it to the skin can help boost skin elasticity and hydration. Studies also show using tea extract may reduce sebum, or oil, production.
