Dual Skin-care Activity of Selected Herbs. Promising 'do-good' Ingredients in Skin Care Formulations?

摘要

The use of natural ingredients have become increasingly popular in the cosmetics. One of the approaches in development of natural skin care/personal care products is the utilization of consortium of herbal extracts that have multiple functional benefits such as antimicrobial, anti-tyrosinase and antioxidant activities for their cognition-enhancing effects in skin care formulations. This study reports the unique attributes of four plants viz. Tridax procumbens, Lantana camara, Thevetia peruviana and Euphorbia hirta with regard to the dual properties of antioxidant and anti-tyrosinase activities and their possible exploitation in skincare products. The results indicate that there is a high positive correlation between anti-tyrosinase activity and antioxidant activity of the extracts of the study plants.
