Glycine Max (Soybean) extract is a plant-derived ingredient rich in isoflavones, proteins, and fatty acids used in skincare for antioxidant, soothing, and skin-brightening effects. It may help reduce hyperpigmentation and improve skin texture by inhibiting protease activity and pigment transfer.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Uncommon | Localized redness, itching, or irritation, more likely in individuals with soy allergy. |
| Mild skin irritation or stinging | Uncommon | Transient irritation on sensitive skin upon application. |
| Systemic allergic reaction | Rare | Reported in highly soy-allergic individuals; generally low risk from topical use. |
| Estrogenic/hormonal concern from isoflavones | Very rare | Theoretical concern from phytoestrogens; topical absorption is minimal and clinical significance is unclear. |
