Common reasons why dry oily skin turns into oily skin:

1. Endocrine reasons.

Human hormones are divided into male hormones and estrogen, and male hormones stimulate oil secretion. Once the sebaceous glands are overactive, they will secrete excess oil.

2. Staying up late and being under too much pressure.

Nowadays, the pace of life is accelerating, the burden of survival is aggravating, and people's pressure is increasing. Frequent staying up late at night and working overtime can also lead to oily skin.

3. The influence of temperature.

Changes in temperature will have an impact on the skin's oil secretion. As the temperature rises, oil secretion will also increase, thereby exacerbating the greasiness of the skin.

4. Caused by genetic factors.

Oily skin refers to those with strong oil secretion, shiny forehead and nose, enlarged pores, blackheads when touched, thick and hard rough cortex, dark yellow appearance, alkaline skin, good elasticity, and resistance to aging. Skin easily absorbs ultraviolet rays.

Extended information:

Oily skin is caused by the strong secretion of sebaceous glands in the human body. The characteristics of the sebaceous glands in the skin are determined by genetic factors. Clinically, skin can be roughly divided into various types according to the amount of lipids on the skin surface: oily skin, dry skin, neutral skin and mixed skin.

For those with oily skin, the secretion function of sebaceous glands is relatively strong. The face is greasy, difficult to clean, and has an unsightly shine. At the same time, it is also prone to corresponding skin diseases on the face, such as acne. Seborrheic dermatitis, etc.

Controlling the excessive secretion of sebaceous glands and reducing the symptoms of oiliness are the keys to maintaining healthy skin.
