Potassium Chloride
Ingredient Info
Potassium chloride is a mineral salt that helps regulate hydration and electrical balance in skin cells. In skincare products, it's typically used as a pH buffer or electrolyte to maintain product stability and skin barrier function.
Benefits
- Helps maintain skin's natural electrolyte balance
- Supports skin hydration at the cellular level
- Acts as a pH stabilizer in formulations
Potential concerns
- May cause irritation or stinging if used in high concentrations
- Can be irritating to sensitive or compromised skin barriers
- Intravenous studies show it can be a vesicant at high doses, though topical skincare concentrations are far lower
Science: The available research focuses primarily on intravenous potassium chloride extravasation complications and its role in swallowing physiology—not topical skincare applications. Limited peer-reviewed data exists specifically evaluating potassium chloride in cosmetic skincare formulations at typical use levels.
