Expert Verdict

Very low irritation potential; lactic acid component provides mild exfoliation at low pH, but as a neutral salt the effect is minimal; well-tolerated by sensitive skin. White crystalline powder; molecular formula C₆H₁₀MgO₆ (MW ~202.45); odorless; good water solubility; serves as a bioavailable magnesium source in skin
