Let's take a look at what's on our faces in the evening.
One category is that we actively apply on the face, such as cream, sunscreen, isolation, foundation, blush, mascara, eye shadow, lipstick and so on, and one is passive adsorption, such as soot in the air, car exhaust, etc.. Can be stubbornly adsorbed on the surface of the skin of things have a characteristic - hydrophobicity, that is, insoluble in water, that is to say, water can not be washed away, not only oil class of things, but also including all kinds of powder. Sunscreen products and makeup products are rich in these hydrophobic ingredients, especially makeup, in order to maintain the durability of makeup, will especially strengthen this kind of performance. A large amount of powder oil attached to the face will block pores, affect the normal metabolism of the skin, and in serious cases will lead to skin inflammation.
