L. in Skin Care: A Review of Its Pharmacological Properties and Cosmetological Applications.

L. (witch hazel) is a traditionally used medicinal plant, well-known for its dermatological applications. The plant's bark and leaves contain a rich array of bioactive compounds, including phenolic acids, flavonoids, catechins, proanthocyanidins, and tannins, many of which exhibit antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties. These activities have been verified by numerous in vitro and in vivo studies, as well as limited clinical trials. The extracts have demonstrated effectiveness against bacteria, fungi, and some viruses. Moreover, the extracts exert anti-inflammatory effects by modulating cytokine expression and NF-κB signaling, improve skin regeneration, and protect against UV-induced damage and pollution. This review highlights as a complex botanical resource to be used in dermatology and cosmetology and shows that current research offers encouraging results for its future therapeutic use, especially in skin treatment.
