Generally, washing twice a day is enough. Facial cleanser can be used twice, but it is best to choose amino acid facial cleanser, which is mild and not irritating. It is best to use refreshing skin care products for mixed oil skin care. It is best not to use cream in summer, or not to use too heavy cream. It is also not recommended to wash your face many times a day. Excessive cleaning will wash the oil on the skin too clean, but it will destroy the stratum corneum, leading to strong oil secretion and easy to block pores.
