What it is
Thymus Vulgaris Extract is derived from thyme, an aromatic Mediterranean culinary herb in the mint family. In skincare it is included for its content of polyphenols and aromatic compounds, which are valued for antioxidant and conditioning effects and sometimes for help in keeping a formula fresh. In sunscreens it typically appears as a minor botanical adjunct rather than as a functional sunscreen agent.
Safety & warnings
Thyme extract and its aromatic constituents can be a source of sensitivity for some users, and thyme-derived essential oil contains naturally occurring compounds that may act as fragrance allergens. People with sensitivity to aromatic herbs or to members of the mint family may wish to patch test. Concentrations used in finished cosmetics are generally low.
Origin & sourcing
Natural; a plant extract obtained from the aerial parts (leaves and flowering tops) of Thymus vulgaris, usually prepared in water, glycol, or glycerin.
History
Thyme has been used in cooking and traditional preparations across the Mediterranean for centuries, and its extract was later adopted as a botanical additive in modern cosmetic formulations.
