Thymus Vulgaris (thyme) Leaf Extract is a plant-derived ingredient rich in thymol, carvacrol, and flavonoids, valued in skincare for its antimicrobial, antioxidant, and anti-inflammatory properties. It is often used in formulations targeting acne, oily skin, and as a natural preservative booster.
| Reported effect | How often | Notes |
|---|---|---|
Contact irritation (stinging, redness) | Uncommon | More likely with higher concentrations or sensitive/compromised skin due to phenolic compounds like thymol. |
Allergic contact dermatitis | Rare | Reported in individuals sensitized to Lamiaceae (mint family) plants or essential oil constituents. |
Photosensitivity | Very rare | Limited reports; generally considered low risk for the leaf extract compared to some essential oils. |
