Science
Mechanism of Action
This extract operates by protecting skin from oxidative damage through free radical scavenging and a notable attenuation of hydrogen peroxide production. Its anti-inflammatory prowess stems from inhibiting critical pro-inflammatory cytokine release, specifically IL-1A and IL-8, and reducing NF-κB activation. Furthermore, it actively contributes to cellular resilience by inducing DNA repair processes in skin cells, complementing its role in improving skin firmness, texture, and reducing the appearance of wrinkles and age spots.

Key findings
- 01 At concentrations from 0.1% to 5%, Paulownia Tomentosa Wood Extract significantly reduces hydrogen peroxide production, demonstrating a dose-dependent antioxidant effect.
- 02 Within the 0.1% to 5% range, the extract significantly inhibits the release of pro-inflammatory cytokines IL-1A and IL-8 in epidermal models.
- 03 Even at very low concentrations (0.001%-0.01%), it effectively inhibits NF-κB activation, a key regulator of inflammatory pathways.
- 04 Studies also indicate its ability to increase DNA damage repair rates in UV-irradiated human keratinocytes.
- 05 Formulations containing 2% to 5% of the extract have been shown to provide benefits for skin lightening, reduce inflammation, and improve signs of aging.

Dusting Analysis
The ingredient demonstrates efficacy across a range of concentrations, including potent effects at very low percentages (e.g., 0.001% for NF-κB inhibition), suggesting that even small amounts can provide targeted benefits rather than indicating a 'dusting' scenario.

Safety
Safety Profile
While formal reviews by CIR, SCCS, or FDA are currently unavailable, the extract is generally considered cosmetically and dermatologically acceptable. This implies it is suitable for skin contact without expected undue toxicity, incompatibility, instability, irritation, or allergic reactions.
