Science
Mechanism of Action
This extract delivers its multifaceted benefits through several key pathways. Fucoxanthin, a powerful carotenoid, acts as a potent antioxidant, neutralizing free radicals and protecting against oxidative stress. It also exhibits significant anti-inflammatory action by inhibiting the NF-κB pathway and reducing pro-inflammatory cytokines such as IL-6, alongside a reduction in Advanced Glycation End Products (AGE). Skin barrier integrity is bolstered by boosting filaggrin production and enhancing cellular longevity, which decreases transepidermal water loss. For hydration, it stimulates endogenous hyaluronic acid synthesis and upregulates Aquaporin-3 levels, facilitating optimal moisture retention and cellular water transport. Its anti-aging efficacy stems from increasing procollagen synthesis and lowering matrix metalloproteinase expression, which collectively improves dermis density, elasticity, and reduces wrinkle depth. Furthermore, it aids gentle exfoliation by increasing the exfoliation index and can contribute to anti-pigmentation by inhibiting melanin biosynthesis.

Key findings
- 01 A 1.5% concentration in a serum visibly reduced wrinkle depth in the crow's feet area by a significant margin after 56 days of consistent use.
- 02 At 0.1%, it increased Aquaporin-3 levels in Normal Human Dermal Fibroblasts, crucial for enhancing cellular water transport and overall skin hydration.
- 03 A low concentration of 0.05% significantly decreased skin permeability on a reconstructed human epidermis, indicating a stronger and more resilient skin barrier.
- 04 Applied at 1.5% in a cream, it increased dermis density in 28 participants over 14 days, leading to measurable improvements in skin firmness and elasticity.
- 05 A 1.5% cream used by 29 participants for 28 days demonstrated improved skin microrelief and a significant increase in the exfoliation index, resulting in smoother, firmer skin texture.
- 06 Studies also show its ability to reduce IL-6 production by 25% and inhibit AGE formation by 10%, highlighting its anti-inflammatory and anti-glycation benefits.
- 07 It stimulated the skin's natural hyaluronic acid production over 56 days, contributing to improved moisture retention and visibly plumper skin.
- 08 In a clinical assessment, it effectively eliminated skin itching in all volunteers within 10 days, significantly enhancing skin comfort.

The Formula
Formulation
Stability
As a hydrolysate, it is typically water-soluble due to the breakdown of cellular components into smaller molecules. While the broader Phaeodactylum Tricornutum Extract can be found in oil-based and water-soluble forms, this hydrolyzed variant primarily functions as a water-soluble ingredient.
Conflicts
- Individuals with allergies to marine substances should avoid use.
Safety
Safety Profile
While generally well-tolerated with rare allergic reactions, individuals with sensitivities to marine ingredients should consider patch testing. Key components like fucoxanthin are recognized as safe by the European Food Safety Authority and US FDA for food and drug applications. However, specific topical safety data for pregnancy and breastfeeding is currently unavailable; professional medical consultation is recommended for these periods.
