A blend of magnesium, zinc, and copper salts (aspartate and gluconate forms) used in skincare to supply bioavailable trace minerals that support enzymatic activity, wound healing, and antioxidant defense. Zinc and copper in particular are studied for roles in collagen synthesis and skin barrier function.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient irritation or stinging | Uncommon | More likely at higher concentrations or on compromised skin barriers. |
Contact dermatitis / allergic sensitization | Rare | Metal salts, particularly nickel-contaminated or copper-containing preparations, may sensitize susceptible individuals. |
Erythema or itching | Uncommon | Generally resolves on discontinuation. |
Localized discoloration from copper | Very rare | Theoretical with high copper exposure; not commonly reported at cosmetic levels. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
