Glycine Soja (Soybean) Seed Extract is a plant-derived extract rich in isoflavones, proteins, and fatty acids used in skincare for antioxidant, moisturizing, and skin-tone-evening effects. It is also studied for inhibiting protease activity, which may help reduce hair regrowth and improve skin texture.
| Reported effect | How often | Notes |
|---|---|---|
Allergic contact dermatitis | Uncommon | May occur in individuals sensitized to soy or legume proteins. |
Skin irritation or redness | Rare | Mild transient irritation reported in sensitive individuals. |
Hypersensitivity reaction in soy-allergic individuals | Rare | Topical use is generally low-risk, but caution advised for those with systemic soy allergy. |
Estrogenic activity concerns | Very rare | Isoflavone phytoestrogen content is a theoretical concern; topical systemic effects considered negligible in research. |
