What Is Thymus Serpyllum Leaf Extract?
Thymus Serpyllum Leaf Extract comes from wild thyme, a small aromatic herb that grows across Europe and parts of Asia. The leaves are rich in natural compounds like thymol, carvacrol, flavonoids and rosmarinic acid, all valued for their soothing and protective traits. People have used wild thyme in folk remedies for centuries, first for its pleasant scent then for its skin calming qualities. Cosmetic chemists began tapping into these benefits in the late 20th century when gentle plant based ingredients started to replace harsher synthetics.
To make the extract, harvested leaves are cleaned, dried and steeped in a solvent such as water, glycerin or a mix of water and propylene glycol. The resulting liquid is filtered to remove plant solids, then standardized so every batch delivers consistent activity. This process keeps the plant’s key molecules intact while removing excess plant matter that could irritate skin.
You will spot Thymus Serpyllum Leaf Extract in toners, light lotions, hydrating serums, sheet masks, soothing after sun gels, anti aging blends and even some scalp or beard care formulas where a fresh herbal feel is welcomed.

Comedogenic Rating
Rating: 0-1
Thymus Serpyllum Leaf Extract is a water or glycerin based botanical with virtually no heavy oils or waxes, so it does not clog pores under normal use. Any residual essential oil components are present in trace amounts that rinse or absorb easily, earning the extract a score at the very low end of the scale.
That means the ingredient is generally suitable for acne-prone or breakout-prone skin.
Only formulas that pair the extract with richer carriers like coconut oil could raise the pore-clogging risk, so check the full ingredient list if congestion is a concern.
