Silver (often as colloidal silver, silver nanoparticles, or silver salts) is used in skincare and wound care for its broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses. It is incorporated into topical products and dressings to reduce microbial colonization.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or contact dermatitis | Uncommon | Localized redness, itching, or stinging at the application site. |
| Localized skin discoloration (local argyria) | Rare | Bluish-gray pigmentation of skin from silver deposition with prolonged or high exposure. |
| Generalized argyria | Very rare | Permanent slate-gray discoloration of skin and mucous membranes, typically from chronic systemic ingestion rather than topical use. |
| Allergic hypersensitivity reaction | Rare | Delayed-type allergic response in sensitized individuals. |
| Delayed wound healing or cytotoxicity | Uncommon | High concentrations may be toxic to keratinocytes and fibroblasts, potentially impairing healing. |
