POLYGONUM TINCTORIUM LEAF/STEM EXTRACT

Description

Polygonum tinctorium leaf/stem extract, derived from the Japanese indigo plant, is a potent botanical ingredient gaining attention in skincare formulations. This extract is rich in indirubin, a compound known for its anti-inflammatory and antioxidant properties. Research suggests it may help soothe irritated skin and protect against environmental stressors.

The extract's ability to inhibit the production of pro-inflammatory cytokines makes it particularly beneficial for sensitive and reactive skin types. It has shown promise in managing conditions like atopic dermatitis and psoriasis. Additionally, its antioxidant capacity helps combat free radical damage, potentially slowing signs of premature aging.

Polygonum tinctorium extract also demonstrates antimicrobial properties, which may aid in balancing the skin's microbiome and managing acne-prone skin. Its natural blue pigment, while not typically visible in final formulations, contributes to its unique properties.

When incorporated into skincare products, this extract is typically used at concentrations between 0.1% and 2%. It pairs well with other soothing ingredients like centella asiatica and can be found in serums, moisturizers, and targeted treatments for sensitive or compromised skin.
