Ajugasterone C is a plant-derived phytoecdysteroid primarily used in skincare and cosmetic formulations due to its anti-aging properties. It helps stimulate collagen production, improving skin elasticity and reducing the appearance of fine lines and wrinkles. Its adaptogenic-like activity supports the skin’s resistance to stress and environmental damage. It is also investigated for its potential to promote hair growth by enhancing follicle activity and extending the anagen (growth) phase of hair. In biological and pharmacological research, it is studied for anti-inflammatory effects and immune system modulation, with potential to reduce chronic inflammation and influence protein synthesis related to cellular stress responses. Due to its natural origin, it is incorporated in plant-based drug development and dietary supplements claiming to enhance physical performance, though additional studies are required to confirm efficacy and long-term safety.
