This is a very common reaction to the initial uses of topical magnesium. It is, after all, similar to being in a very salty ocean. This sensation usually subsides within a few uses. If it is bothersome, try to wait 20 minutes for full absorption, then wash off or apply a lotion. In rare cases, this reaction can also be experienced with sensitive or irritated skin. In this case, experiment with diluting the product with diluted water for the Magnesium Spray or with an oil/cream such as coconut oil for the Magnesium Creams.
