Zinc is a trace mineral used in skincare for its anti-inflammatory, antimicrobial, and sebum-regulating properties, commonly in forms such as zinc oxide, zinc PCA, and zinc gluconate. It is widely used in acne treatments, sunscreens, and products for sensitive or irritated skin.
| Reported effect | How often | Notes |
|---|---|---|
Mild dryness or tightness | Uncommon | More likely with sebum-regulating zinc salts in higher concentrations. |
Skin irritation or redness | Uncommon | Typically mild and transient, often related to formulation pH or other ingredients. |
Allergic contact dermatitis | Rare | Sensitization to zinc compounds is documented but infrequent. |
White cast or temporary residue | Common | Specific to zinc oxide in sunscreens, particularly non-nano grades. |
Stinging on broken or compromised skin | Rare | Reported when applied to open lesions. |
