Science
Mechanism of Action
Codium Tomentosum Extract provides enduring and efficient hydration by creating a water reservoir through a dual mechanism. Firstly, sulphated phycocolloids from the extract attach to skin proteins, forming a protective barrier that limits water loss. Secondly, osmoregulating molecules penetrate superficial epidermal layers, significantly boosting the skin's natural moisturizing factor (NMF) activity. Beyond hydration, it normalizes moisture balance, supports natural exfoliation, and contributes polysaccharides and lipids for environmental protection. Rich in minerals and vitamin A, it encourages healthy cell production in deeper skin layers, stimulating blood circulation and cell renewal.

Key findings
- 01 A 5% extract-containing cream immediately doubled skin moisture, maintaining high levels for over three hours. After eight days of application, moisture levels were over 20% higher than placebo, and the extract enhanced the placebo's moisturizing effect by 50%.
- 02 Twice-daily application of a 5% Codium extract cream for seven days showed forearm skin moisture levels remaining an average of 15% higher than control groups after six hours, significantly outperforming creams without the active.

The Formula
Formulation
Stability
Formulations containing Codium Tomentosum Extract at concentrations as low as 0.15% have demonstrated structural instability, indicating a potential requirement for co-formulation with hydrocolloids or other stabilizing agents. Additionally, the inherent strong sensory characteristics of seaweed extracts can pose formulation challenges, potentially requiring careful masking or consideration in product design. While a pH range of 4.26-4.40 was noted for stability in encapsulated food applications, specific optimal pH for cosmetic formulations is not clearly established.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has classified Codium Tomentosum Extract with 'insufficient data' for a complete safety assessment, and no specific maximum concentration for use is provided. The Environmental Working Group (EWG) has identified 'high' contamination concerns regarding Iodine, Arsenic, and Lead for this ingredient. While it can be used in EWG VERIFIED products, it necessitates strict adherence to use restrictions, warnings, and substantiation of purity. EWG's assessment also indicates 'low' concerns for cancer, allergies/immunotoxicity, and developmental/reproductive toxicity. No specific SCCS or FDA regulatory status is detailed.

Verdict
While Codium Tomentosum Extract delivers significant, long-lasting hydration and skin barrier support, its 'high' contamination concerns for heavy metals necessitate rigorous sourcing and purity verification for use in precision skincare formulations.
