CARUM PETROSELINUM EXTRACT.

Valuable CAS 84012-33-9 / SKIN CONDITIONING

A high-performance botanical extract derived from parsley, prized in precision skincare for its high concentration of apigenin and flavonoids. It serves as a multifunctional bioactive that targets hyperpigmentation, oxidative stress, and inflammatory pathways simultaneously.

Summary

Tyrosinase Inhibition Antioxidant Anti-inflammatory Barrier Reinforcement

Science

Mechanism of Action

This extract utilizes a four-pronged approach: it inhibits tyrosinase activity to modulate melanin synthesis; neutralizes reactive oxygen species via Nrf2 pathway activation; suppresses pro-inflammatory cytokines (IL-6, IL-8, and IL-33) by blocking JAK1/STAT1 and NF-kB signaling; and reinforces structural integrity by upregulating the barrier proteins filaggrin and claudin-1.

Key findings

  1. 01 A randomized controlled trial (2016) demonstrated that a concentrated parsley preparation reduced Melasma Area and Severity Index (MASI) scores by approximately 25% over 8 weeks, matching the efficacy of 4% hydroquinone.
  2. 02 Clinical observation of dermatitis patients (2024) showed significant reduction in erythema, epidermal thickness, and scaling following topical application.
  3. 03 Consumer trials of 50% concentration masks indicate immediate cooling and soothing effects without reported irritation.
