Nano Gold 24Kt refers to colloidal gold nanoparticles used in skincare for claimed antioxidant, anti-inflammatory and skin-brightening effects, though robust clinical evidence is limited. It is marketed as an anti-aging active ingredient.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation or mild redness | Uncommon | Localized transient irritation at application site. |
| Allergic contact dermatitis | Rare | Gold is a known sensitizer; delayed hypersensitivity reactions possible in susceptible individuals. |
| Skin discoloration (chrysiasis-like) | Very rare | Pigmentary changes more associated with systemic gold exposure than topical nanoparticles. |
| Potential nanoparticle skin penetration concerns | Rare | Theoretical safety concern under research; long-term effects not fully characterized. |
