Revealing the Therapeutic Potential: Investigating the Impact of a Novel Witch Hazel Formula on Anti-Inflammation and Antioxidation.

BACKGROUND

Skin barrier health is crucial for preventive and corrective skincare across all skin types. Witch hazel (Hamamelis virginiana) extracts show potential in addressing skin issues, but their efficacy in treating chronic inflammation, improving skin barrier function, and combating UV-induced oxidation requires further investigation.

AIMS

To evaluate the efficacy of a novel formula containing witch hazel extracts in treating chronic inflammation, improving skin barrier function, and combating UV-induced oxidation.

METHODS

We employed a novel ex vivo chronic inflammation model to assess anti-inflammatory effects, measuring key pro-inflammatory cytokines. Barrier function markers, such as loricrin and transglutaminase-1, were analyzed. An ex vivo model with UV-induced Reactive Oxygen Species (ROS) elevation was used to evaluate antioxidant properties, measuring specific ROS markers like 4-Hydroxynonenal and carbonylated protein.

RESULTS

The novel witch hazel formula significantly reduced pro-inflammatory cytokines in both 2D and ex vivo models, including IL-6 and IL-8, demonstrating potent anti-inflammatory effects. Barrier function markers showed notable improvements compared to the inflamed condition. In the UV-induced ROS model, the formula remarkably decreased ROS levels, specifically 4-Hydroxynonenal and carbonylated protein, indicating strong antioxidant properties.

CONCLUSIONS

Our findings demonstrate that the novel witch hazel formula exhibits potent anti-inflammatory and antioxidant properties while enhancing skin barrier function. This natural, well-tolerated ingredient offers a promising treatment option for improving overall skin health, presenting new opportunities in skincare formulation and treatment strategies.
