Science
Mechanism of Action
Phaeodactylum Tricornutum Extract operates via several precise mechanisms to improve skin health. It significantly increases Aquaporin-3 (AQP3) production, optimizing water transport within skin cells for enhanced hydration and moisture balance. The extract strengthens the skin barrier by reducing permeability, and it boosts dermis density, contributing to improved skin firmness and elasticity. It also facilitates gentle exfoliation and stimulates natural hyaluronic acid synthesis and cell renewal. Furthermore, it demonstrates potent antioxidant effects by protecting against oxidative stress and neutralizing free radicals, alongside anti-inflammatory properties through the inhibition of IL-6 production, reduction of Advanced Glycation End Products (AGEs), and modulation of the NF-κB signaling pathway. Its hygroscopic nature acts as a humectant, and it promotes proteasome activity for cellular vitality.

Key findings
- 01 Demonstrated an increase in Aquaporin-3 (AQP3) levels in Normal Human Dermal Fibroblasts (NHDF), leading to improved skin hydration and moisture regulation.
- 02 Significantly reduced the permeability of a reconstructed human epidermis when exposed to a stressor, indicating a strengthened skin barrier function.
- 03 Increased dermis density, resulting in firmer and more elastic skin, as observed in a cream applied by 28 participants over 14 days.
- 04 Showed a significant increase in the exfoliation index, promoting skin regeneration, with effects evident after 14 days in a 28-day study involving 29 participants.
- 05 Reduced the depth of wrinkles in the crow's feet area in a clinical study where a serum was applied for 56 days.
- 06 Significantly reduced oxidative and inflammatory stress markers (ROS, NO, IL-1α), cytotoxicity, and sunburn cells induced by UVA and UVB in in vitro reconstructed human epidermis models, showing an excellent safety profile.
Transparency
Dusting Analysis
While Phaeodactylum Tricornutum Extract exhibits measurable benefits for hydration, barrier reinforcement, and anti-oxidative/anti-inflammatory effects at concentrations as low as 0.05% to 0.1%, studies demonstrating visible structural improvements such as increased dermis density, enhanced exfoliation, and wrinkle reduction consistently utilized a concentration of 1.5%. Therefore, products making claims related to these higher-tier anti-aging or structural benefits at concentrations significantly below 1.5% may be considered to be dusting, as they might not deliver the full advertised efficacy.
The Formula
Formulation
Stability
This extract is available in both oil-based and water-soluble formulations, providing excellent versatility for diverse product development. While no specific optimal pH range for the entire extract in cosmetic formulations was identified, some components, such as C-phycocyanin, exhibit enhanced stability between pH 5 and pH 7.
Safety
Safety Profile
Phaeodactylum Tricornutum Extract is listed in the FDA UNII database (Y5W63E7HLV). Adverse reactions are considered relatively uncommon, and the ingredient has demonstrated an excellent safety profile in photoprotective studies. It is rated as an 'Outstanding active ingredient' by Paula's Choice. Due to a lack of specific data regarding topical usage during pregnancy and breastfeeding, consultation with a healthcare professional is advisable, and a preliminary patch test is recommended before widespread application.
