Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Camellia Sinensis Leaf is the leaf of the tea plant. These leaves are used to make white, oolong, green, and black tea.
Tea leaves have 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.
Research has shown both drinking Camellia Sinensis Leaf Tea (green tea, white tea, oolong, black 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.
