Abstract
Background: Skin aging results from intrinsic and extrinsic factors, including oxidative stress, ultraviolet (UV) radiation, and declining cellular functions. These factors lead to visible changes like rhytids, pigmentation, and loss of elasticity. Meanwhile, interest in plant-based skincare ingredients for skin aging has been increasing.
Objective: This systematic review investigates the anti-aging potential of Astragalus membranaceus, a botanical plant. The authors focused on its active components and their roles in dermal protection, antioxidant, anti-inflammatory, anti-aging properties, and telomere elongation.
Methods: A comprehensive PubMed search from 2015 to 2025 per PRISMA guidelines identified clinical and experimental studies assessing the anti-aging effects of Astragalus membranaceus.
Results: Bioactive compounds, including astragaloside IV, cycloastragenol, flavonoids, and polysaccharides, showed photoprotective effects, including reactive oxygen species (ROS) reduction, inflammatory signaling inhibition, mitochondrial preservation, and promotion of collagen synthesis. Elongation of telomeres under oxidative stress was also demonstrated with Astragaloside IV. Clinical trials showed improvements in skin hydration, tone, and wrinkle reduction.
Conclusion: Astragalus membranaceus offers promise as a botanical anti-aging agent. Its effects on collagen, oxidative defense, and telomere preservation support its potential use in cosmeceuticals. However, further randomized trials are needed to confirm long-term efficacy and safety.

 

INTRODUCTION

Skin aging is an inevitable biological process, regardless of skin type. This natural progression of dermal senescence is influenced by intrinsic and extrinsic factors, where intrinsic aging refers to the skin's natural physiological decline characterized by a reduction in elasticity and collagen, skin thinning, and dryness.1 Extrinsic aging is mediated through environmental stressors like ultraviolet (UV) radiation, pollution, and lifestyle factors such as smoking and inadequate nutrition.1 This dual mechanism accelerates skin aging, leading to visible changes such as deep wrinkles, uneven skin tone, and loss of skin firmness.1,2

The demand for cosmetic strategies to mitigate these changes has grown in popularity, with more individuals seeking solutions to maintain a youthful appearance.1 Among the various approaches to skin rejuvenation, natural plant-based agents, such as those derived from Astragalus membranaceus, have garnered attention due to their perceived safety and holistic benefits.3

Astragalus membranaceus (Figure 1) has been a cornerstone of traditional Chinese medicine for over 2 millennia, and it is recognized for its wide-ranging therapeutic properties, including skin anti-aging.4 The root of Astragalus membranaceus is rich in bioactive compounds such as polysaccharides, flavonoids, and saponins.5,6 These herbal compounds have been shown to be effective in mitigating skin aging through mechanisms of enhanced antioxidant and anti-inflammatory activity, collagen preservation, and UV protection.6,7 These properties not only address visible signs of aging but also support the skin's structural integrity and resilience. Furthermore, astragaloside IV is a powerful astragalus-based triterpenoid saponin that can elongate telomeres, a key marker of cellular aging and a promising target for developing anti-aging interventions.1 By elucidating Astragalus membranaceus's molecular mechanisms, this herb can provide natural and effective solutions for skin aging.
