Oily skin mainly has three aspects:

1, endocrine disorders, stimulate oil secretion, mainly androgen. Hormones control the secretion rate of sebaceous glands. If the sebaceous glands secrete too much, it will lead to too much oil secretion.

2, the temperature is too high, the skin will also increase the secretion of oil.

3, the work and rest is not normal, and the skin needs to rest. Regular life can make the skin get enough rest, so as to achieve the balance of water and oil.
