What it is
Astragalus sinicus is a leguminous plant traditionally grown as a green-manure cover crop in East Asia, and its extract is incorporated into cosmetics as a plant-derived conditioning ingredient. In leave-on formulas such as sunscreens it is typically included at low levels to support a soft, comfortable skin feel rather than to provide sun protection. It contributes to the botanical, skin-friendly positioning of a product and does not absorb or scatter ultraviolet light.
Safety & warnings
Botanical extracts of this type are generally well tolerated in cosmetic use. As with any plant-derived ingredient, sensitive or allergy-prone individuals can occasionally react, and patch testing is reasonable for very reactive skin. It is not a recognized fragrance allergen and is not an oil, so comedogenicity is not a meaningful concern at typical use levels.
Origin & sourcing
Natural; a water or hydroglycolic extract prepared from the aerial parts or whole plant of Astragalus sinicus, a legume native to East Asia.
