Oily skin is a common physiological phenomenon that affects each of us' daily life and skin care habits. But why does skin produce oil, and what is the biological mechanism behind it? This article will explore the causes of oily skin and provide some effective ways to manage and control oily skin.

Skin structure and oil production
  Skin is made up of three layers: epidermis, dermis, and subcutaneous tissue. Among these layers, sebaceous glands play an important role. They are mainly found on the face, back and chest and are the main producers of sebum. Sebum is an oil composed of fatty acids, wax esters, and cholesterol that lubricates and protects the skin from environmental damage.

Why does skin become oily?
  Sebum production is affected by many factors. The main ones are hormones, especially androgens, which stimulate the enlargement of sebaceous glands and increase sebum production. In addition to hormonal levels, genetics, diet, life stress, and environmental factors such as temperature and humidity can also affect your skin's oil production.

Effects of excessive oil production
  When sebum is overproduced, it can cause clogged pores, the formation of blackheads or pimples, and even the development of acne. In addition, excessive oil production may make the skin look shiny and affect the appearance.

How to manage and control oily skin

• Clean properly: Use gentle cleansing products and avoid over-cleansing, which can stimulate excessive sebum production.
• Use non-oily skin care products: Choose water-based rather than oil-based skin care products to reduce oil buildup.
• Diet and Lifestyle: Maintain a balanced diet and avoid foods high in sugar and fat; maintain proper stress management and get enough sleep.
• Medication: In severe cases, you can consult a dermatologist to use medication to regulate sebum secretion.

While oily skin is a natural phenomenon, it can be effectively managed and controlled with proper care and lifestyle adjustments. Understanding the causes of oily skin and taking the right care can help keep your skin healthy and beautiful.
