Masks come in different forms including clay, peel off, self-heating, exfoliating, cream and food-based masks. What we're used to often is the clay mask. Clay masks generally help in absorbing excess oil from the face as well as do away with blemishes caused by acne. It is often made from bentonite, which is has been used in the beauty industry for ages.
If you haven't started exfoliating yet, then the time to start is now. If you have, kudos! In the short term, exfoliating helps give your skin a brighter look and makes it easier for products to be easily absorbed into the skin as well as helps prevent the incidence of having clogged pores. This reduces the formation of acne on your face. In the long term, exfoliating helps in the production of collagen which makes the skin vibrant.
If you have oily skin because of your genes, it may be very difficult doing away with it completely. Staying away from sugar-rich foods, processed foods and fried foods might help. Avoid using very heavy make-up as well and continue taking good care of your skin
