Magnesium gluconate, the magnesium salt of gluconic acid, is a skin-conditioning ingredient. Despite its mineral origin, it’s considered a synthetic ingredient.
Skin-conditioning ingredients work overtime to help improve the appearance of skin, increasing smoothness and reducing flakiness, roughness and a dry texture.
Outside of cosmetics, magnesium gluconate is used as a supplement for those who need more magnesium.
Currently, there’s not enough peer-reviewed research to support further skin benefits of magnesium gluconate. The Cosmetic Ingredient Review Expert Panel hasn’t yet reviewed this ingredient. It may play a role in improving barrier health by making magnesium more bioavailable to skin, and the gluconic acid salt has light humectant properties.
