Astragalus membranaceus (Huangqi) is an important herb in traditional Chinese medicine, where it is used for the treatment of a variety of diseases and disorders and is marketed as a life-extending supplement for over 2000 years.

One of the major active components extracted from Astragalus membranaceus is Astragaloside IV, which has been found to decrease the rate of environmentally induced breakdown of collagen in the skin, especially due to ultraviolet radiation.

As we grow older, the balance between collagen damage and repair is disrupted, leading to the overall loss of collagen. Astragaloside IV helps restore skin collagen to a younger and more balanced state.
