This helps to reduce the outbreak of blemishes, alleviate redness, and also to fight allergic reactions from irritating lotions or face washes. Thanks to the clay’s special ability to act as an antibiotic treatment when applied topically to the skin, the clay can help to calm skin infections, like contact dermatitis and speed up healing time of wounds. Bentonite clay is great for you. It opens and cleans the facial pores to eliminate pimples.
