People with normal skins start showing signs of age and wrinkling sooner than others, if they tend to neglect their skins. They produce more oil than is needed, which oozed up, giving the skin a greasy shine. The pores are enlarged and the skin has a coarse look. It is also prone to black heads, pimples and acne. Oily skin need special cleansing to keep the pores unclogged.
Hormonal imbalances can also upset the oil balance and increase sebaceous gland activity.
The skin lacks both sebum and moisture. It looks fine textured, transparent, patchy and fragile. There may be tiny expression lines and there may even be crepyness. It flakes and chaps easily. There are many factors, which affect dry skins and make them, even more dry.
