What it is
Soybean seed extract is derived from the seeds of the soybean plant (Glycine soja). It is rich in isoflavones (like genistein and daidzein), proteins, and fatty acids, which contribute to its antioxidant and skin-conditioning benefits.
How it works
In skincare, soybean seed extract works by neutralizing free radicals (unstable molecules that can damage skin cells) thanks to its antioxidant content. It also has mild anti-inflammatory effects that can help calm irritated skin, and its fatty acids support the skin's natural moisture barrier.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing properties
Helps calm redness and inflammation, which can be beneficial for conditions like mild rosacea or post-exfoliation sensitivity.
Cons and cautions

The concentration of active compounds can differ between products, leading to inconsistent results.
