Salvia officinalis (sage) extract is a plant-derived ingredient rich in polyphenols, rosmarinic acid, and essential oil compounds, used in skincare for its antioxidant, antimicrobial, astringent, and anti-inflammatory properties. It is commonly included to help soothe skin, reduce oiliness, and provide mild preservative-boosting effects.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation | Uncommon | Mild stinging or redness, more likely on sensitive or compromised skin, partly due to essential oil and thujone content. |
| Allergic contact dermatitis | Rare | Reported sensitization to Lamiaceae-family botanicals and their fragrance/essential oil constituents. |
| Photosensitivity | Very rare | Occasional reports linked to certain plant phenolic or essential oil components; not well established for cosmetic concentrations. |
