Ocimum Sanctum (Holy Basil/Tulsi) leaf extract is a plant-derived ingredient rich in eugenol, flavonoids, and phenolic compounds valued for antioxidant, anti-inflammatory, and antimicrobial properties. In skincare it is used to help soothe skin, combat oxidative stress, and support blemish-prone or aging skin.

Skin irritation or redness | Uncommon | More likely with high concentrations or in individuals with sensitive skin. |
Photosensitivity | Very rare | Limited reports; generally not considered phototoxic at cosmetic levels. |
