Caution: Avoid using if you have dry/sensitive skin

I have combination skin, containing both oily as well as dry patches around my skin. While applying the product, I found that it irritated and burned my dry spots on my face. The oily/neutral areas of my skin were fine though. However, I did not see much of an effect with my pores, as well as my blackheads. It is a decent clay mask, but not the best one.
