What Is Rehmannia Chinensis Root Extract?
Rehmannia chinensis root extract is the extract from the roots of a plant also known as Chinese foxglove. It has long been used in traditional Chinese medicine, where it is known as dihuang or gan dihuang.
Limited research shows Rehmannia chinensis root extract is a source of vitamins C and D and exhibits anti-aging properties when applied topically. Some studies indicate that it can also help diminish the appearance of dark spots and uneven tone. While more research is needed, it’s certainly an ingredient to watch when it comes to plant extracts’ impact on skin health and appearance.
