What it is
Thymus serpyllum extract is obtained from wild thyme, an aromatic perennial herb in the mint family. In cosmetic formulations it serves as a botanical conditioning agent and is valued for the antioxidant character associated with thyme constituents. It is generally used at low concentrations as part of a plant-based blend.
Safety & warnings
Thyme-derived materials can contain aromatic constituents that may cause sensitivity in some individuals, particularly those reactive to Lamiaceae (mint family) plants. At the low levels used in cosmetics the extract is generally well tolerated, though fragrant essential-oil components, if present, can be a source of irritation for sensitive skin.
Origin & sourcing
Natural; prepared from the aerial parts of the wild thyme plant (Thymus serpyllum), typically in a water or glycol solvent.
