Neem Extract description

Primarily from India where it has a long and storied history, neem extract can be from the bark, seed, or leaf of this plant; the root, flower, and fruit forms are rarely used in skincare products. The extracts have antioxidant and skin-calming benefits and may also help reduce the population of harmful microbes on skin's surface. Polysaccharides in neem extract can contribute to skin's hydration level, while significant antioxidants include quercetin and beta-sitosterol. Neem stem as a water-based extract contains multiple beneficial ingredients for skin that are believed to help visibly repair its appearance and improve hydration.
