Do this only on new pimples that have not been squeezed or open or have open skin nearby. If you apply it to open skin, there's a possibility that you will create irritation if the clay gets into the skin.
A secondary benefit of this treatment is that it gives you something to do to reduce the lesions instead of squeezing them, which can force the contents to break out underneath the skin and cause the formation of large cyst. Some clays are more effective than others, And some custom combination clays may be far more effective. Be sure to stop using clay if you get too much dryness or irritation or itching.
To your health,
