Science
Mechanism of Action
This ingredient functions by improving skin's natural tolerance and safeguarding against dehydration. Its beneficial effects stem from bioactive components, including flavonoids and tannins, which collectively offer antioxidant, moisturizing, and anti-inflammatory properties. These components work to neutralize free radicals, thereby mitigating visible signs of aging, supporting skin elasticity, and attracting moisture to maintain hydration. Furthermore, it aids in calming sensitive skin, reducing redness and discomfort.

Key findings
- 01 Polygonum Fagopyrum (Buckwheat) flour acts as a skin conditioning agent, helping to restore, increase, or improve skin tolerance to external factors and preventing skin dehydration.
- 02 Fagopyrum esculentum extract demonstrated strong antioxidant activity, exhibiting 81.64% radical scavenging effectiveness at a concentration of 1 mg/ml. (Note: This specific finding applies to an extract, not directly to the flour.)

The Formula
Formulation
Stability
As a flour, this ingredient typically forms a particulate dispersion within formulations. Its inherent water absorption capacity is crucial for achieving desired product texture and consistency. While starch characteristics and amylase activity are primarily studied for food applications, they may influence long-term stability in cosmetic formulations if not appropriately managed. Specific water-extractable dietary fiber components present in the flour are water soluble.
Safety
Safety Profile
No direct safety assessments by CIR or SCCS for Polygonum Fagopyrum Flour have been published. A related ingredient, Polygonum Fagopyrum Seed Extract, possesses an excellent safety profile and is approved for cosmetic use in the EU, though moderate concentrations are advised to prevent potential adverse reactions. Buckwheat inherently contains phototoxic fagopyrins; while the flour is generally safe in standard cosmetic amounts, high consumption of buckwheat sprouts or concentrated fagopyrin extracts can induce fagopyrism (sunlight-induced skin inflammation). SkinSAFE categorizes Polygonum Fagopyrum Flour as 'Irritant Free,' and its irritancy is generally considered low. Individuals with known buckwheat allergies or particularly sensitive skin should exercise caution due to potential irritation. The ingredient is associated with CAS Number 89958-09-8 and ECHA EC Number 289-631-2.
