Medicago Sativa Extract

Medicago sativa (alfalfa) extract is a botanical skin-conditioning/antioxidant ingredient typically used at low concentrations, but plant extracts contain multiple bioactive proteins and phytochemicals that can trigger irritant or allergic contact reactions in a small subset of sensitive users. Patch-test and case-report experience with botanicals supports occasional sensitivity—especially in eczema-prone skin or when layered with other actives—so I score it as mild rather than “gentle” for safety. Safety Notes: In commercial skincare, Medicago sativa (alfalfa) extract is most often used as a minor botanical support ingredient in multi-extract blends, where finished-product levels can be as low as ~0.0005–0.05% (especially when the INCI refers to a carrier-diluted extract). Higher-strength consumer leave-on serums/creams and “botanical concentrate” products sometimes dose the extract at ~1–3%, with the upper end around ~5% seen in OTC formulations using the extract as a primary story ingredient. There is no specific FDA/EU concentration cap for this botanical extract; practical limits are driven by supplier recommended use levels, odor/color, and stability/compatibility rather than regulation.
