Dry skin contains a lesser degree of sebum and moisture, which is why it is easily irritated. Dry skin is dehydrated and therefore the possibility of cracking and wrinkles is rather high. Dry skin is very vulnerable to climate changes. Chips and cracks are attributes of dry skin so it needs accurate treatment and care. To prevent your skin from withering use richly hydrating and moisturizing creams and periodically keep your skin in contact with water. Unlike dry skin, oily skin retains a high degree of sebum, and consequently the skin usually looks greasy. The greasy layer does not let your skin breathe and pores fill up very quickly. Oily skin attracts more contaminants and harmful components, but on the other hand it prevents the appearance of wrinkles to some extent. The best thing to do in this case is to wash the face with hot water and use non-oily creams. Normal skin is the most desired type of skin and is a happy medium. The quantity of sebum is normal and balanced. The pores are clean and the skin is healthy and flawless. Normal skin must not be taken for granted, it also deserves attention and care.
