Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

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.

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

Camellia Sinensis Leaf Extract also has antimicrobial properties.

My HG barrier serum! After I started incorporating this into my routine a couple months ago, my skin has seriously gotten so much better. I struggled with inflammation and irritation, and this serum calms down my skin so much. I love that it not only contains Centella extract, but also its active ingredients which make it more potent. It also contains amazing stuff like niacinamide, ceramide, and peptide. Will always always repurchase. (Literally need to restock asap)
