Zinc chloride is an inorganic zinc salt used in skincare and topical formulations as an astringent and antimicrobial agent, and in higher concentrations as a caustic/escharotic in dermatologic procedures. It can help reduce surface microbial load and tighten tissue.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation and stinging | Common | Especially at higher concentrations; transient burning or redness on application. |
Dryness or flaking | Common | Due to its astringent, moisture-reducing action. |
Chemical burn or tissue necrosis | Uncommon | At high (escharotic) concentrations, can cause caustic injury and scarring. |
Allergic contact dermatitis | Rare | Hypersensitivity reactions reported in sensitized individuals. |
Hyperpigmentation or scarring | Rare | More likely after caustic use or on compromised skin. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
