Thyme Leaf Water (Thymus vulgaris distillate) is an aromatic plant water used in skincare for mild antimicrobial, antioxidant, and soothing properties. It typically functions as a low-concentration botanical additive or aqueous base component rather than a primary treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or stinging | Uncommon | May occur on sensitive or compromised skin, partly due to residual thymol and other volatile constituents. |
Allergic contact dermatitis | Rare | Reported in individuals sensitized to Lamiaceae-family plants or aromatic compounds. |
Photosensitivity-related reactions | Very rare | Limited reports; generally considered low risk for plant waters compared to essential oils. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
