Alfalfa (Medicago sativa) extract is a plant-derived ingredient rich in vitamins, minerals, amino acids, and phytochemicals such as saponins and flavonoids, used in skincare for its antioxidant and skin-conditioning properties. It is typically included as a soothing, nourishing botanical additive rather than a clinically proven primary active.

| Skin irritation | Uncommon | Mild stinging or redness, more likely in sensitive skin or with high-concentration extracts. |
| Photosensitivity | Very rare | Some plant phytochemicals may theoretically increase sun sensitivity, though rarely reported for alfalfa. |
