Science
Mechanism of Action
Glycine Soja Extract operates through multiple pathways to improve skin health. It functions as a potent antioxidant by neutralizing free radicals and scavenging peroxyl radicals, thereby combating oxidative stress. For anti-aging, it actively stimulates both collagen and elastin production while inhibiting elastase activity, which collectively helps to diminish the appearance of fine lines and wrinkles. The extract provides skin conditioning, moisturizing, and emollient benefits by supporting skin hydration, improving softness, and reinforcing the moisture barrier. Additionally, it aids in skin brightening by hindering melanosome transfer, and possesses soothing, anti-inflammatory properties that reduce redness and sensitivity. Its active components include isoflavones, peptides, phenolic acids, flavonoids, and proteins.
Research
Clinical Evidence
Medium confidence0.02%
Key findings
- 01 In vitro studies revealed that soybean extracts at these concentrations significantly induced elastin promoter activity, inhibited elastase, and protected elastic fibers from degradation. Fibroblast cultures treated with this range exhibited increased elastic fiber networks, indicating potent anti-aging potential.
- 02 Sensitization data for Glycine Soja Extract used at concentrations up to 2% in leave-on face and neck products demonstrated its safety for topical application.

Dusting Analysis
Glycine Soja Extract demonstrates specific anti-aging efficacy, particularly in supporting elastic fiber networks, at concentrations as low as 0.02-0.05% in in-vitro research. While safe for use up to 2%, formulations containing less than 0.02% may fall below the effective threshold for optimal benefit delivery.
The Formula
Formulation
Stability
The extract is typically processed using water, glycerin, or mild solvents, ensuring its compatibility within a broad range of natural and clean beauty formulations.
Safety
Safety Profile
The CIR Expert Panel has assessed Glycine Soja Extract as safe for cosmetic use under current practices, with usage typically up to 2%. It is generally well-tolerated across skin types, with a low hazard rating (EWG 1) and minimal concerns for irritation or toxicity. Rare allergic reactions may occur in individuals highly sensitive to soy, for whom patch testing is advised. The phytoestrogen compounds present are not considered hormones and are widely recognized as safe for topical application.
