Science
Mechanism of Action
This extract functions as a broad-spectrum skin protector, effectively neutralizing free radicals and mitigating lipid peroxidation to prevent premature aging. Its anti-inflammatory properties significantly reduce irritation and decrease the expression of cyclooxygenase-2, a key enzyme involved in inflammatory responses. Additionally, it demonstrates antibacterial and antifungal activities, which are beneficial for managing sebum overproduction and related skin concerns. Through its tannin content, it enhances skin hydration, helps restore moisture balance, and fortifies the skin barrier. The extract also promotes skin renewal, acts as a brightening agent by inhibiting melanin transport to epidermal cells, and can stimulate local blood flow. Furthermore, it serves as both a masking agent and a natural fragrance in cosmetic formulations.

Stability
While the source plant adapts to a wide pH range (mildly acid to basic) in nature, formulating with its extract requires careful consideration of oxidative stability. Phenolic compounds within the extract are prone to oxidation by polyphenoloxidase, which can lead to browning and challenges in vitro.
Safety
Safety Profile
Generally recognized as a safe cosmetic ingredient. However, individuals sensitive to plants from the Lamiaceae family may experience allergic reactions or irritation. Paula's Choice indicates a likelihood of irritation, noting that this risk can increase when combined with other potentially problematic ingredients, potentially leading to inflammation or dryness. The FDA has approved 'Thyme, Wild or Creeping, Extract (Thymus serpyllum L.)' as an 'Approved Herbal Substance Name' for non-medicinal purposes.
