The benefit of toothpaste washing is that it only plays a cleansing role for the face, however, toothpaste is not recommended for washing the face. Because although toothpaste has a certain effect on removing dirt from the face, some of the irritating ingredients in toothpaste may cause damage to the skin’s stratum corneum. This may induce some skin diseases, especially irritant dermatitis and allergic dermatitis of the skin. Therefore, toothpaste is not recommended for washing the face. If you forcefully use toothpaste to wash your face, it may cause damage to the stratum corneum and also induce local skin capillary dilation, resulting in flushing of the skin, and in severe cases, skin papules, papules, and even certain vesicles.
