Kesar (saffron, derived from Crocus sativus stigmas) is a plant-derived ingredient used in skincare for its antioxidant carotenoids (crocin, crocetin) and safranal, which are studied for skin-brightening, anti-inflammatory, and UV-protective properties. It is commonly incorporated into creams, serums, and traditional formulations for its purported tone-evening effects.

| Allergic reaction / sensitization | Rare | Possible in individuals allergic to Crocus or related plant compounds. |
| Skin discoloration or staining | Rare | Saffron's natural pigments may transiently tint very fair skin or fabrics. |
| Photosensitivity | Very rare | Limited reports; generally considered safe but data are sparse. |
