Determine whether the sleeping mask is wash-free. Not all cream masks are wash-free, so be sure to read the ingredients carefully when purchasing. Make sure it is wash-free and can be left on the face overnight before it can be called a sleeping mask. If it is not a wash-free mask, it will cause skin damage if applied on the face overnight. Sleeping masks are for dry and dehydrated skin. It is best not to use them overnight on oily skin. Apply it for 15 minutes at most and then wash it off. Otherwise, it will cause acne if you keep it there for too long.
