DRYOPTERIS CRASSIRHIZOMA EXTRACT

Description

Dryopteris crassirhizoma extract, derived from the rhizome of the thick-stemmed wood fern, is a potent botanical ingredient gaining attention in skincare and haircare formulations. This extract contains phloroglucinol compounds, notably filixic acid and aspidin, which contribute to its biological activities.

The extract exhibits notable antioxidant properties, helping to neutralize free radicals and combat oxidative stress in skin and hair cells. It demonstrates antimicrobial efficacy, particularly against Propionibacterium acnes, making it valuable in acne-targeted treatments. Additionally, research suggests anti-inflammatory capabilities, potentially soothing irritated skin and scalp conditions.

In haircare, Dryopteris crassirhizoma extract shows promise in promoting hair growth by inhibiting 5α-reductase activity, an enzyme involved in hair loss. Its astringent properties may help regulate sebum production, benefiting both oily skin and scalp.

Formulations incorporating this extract typically use concentrations between 0.1% to 1%. It is water-soluble, facilitating its inclusion in various product types. While generally well-tolerated, patch testing is recommended due to potential sensitization in some individuals. Further research is ongoing to fully elucidate its mechanisms of action and optimal application in cosmetic products.
