Combination Skin Causes

After birth, abundant and fully functioning sebaceous glands are present in human skin, and the sebum level on the skin is high. During the first year of life, the sebaceous glands regress, and by puberty, correspondingly little oil is detectable on the skin surface. Greasing of the surface by sebum can also be expected before puberty, since some sebaceous cells in the glands also decay during this age phase. During puberty, under the influence of testosterone, there is a new full maturation and function of the sebaceous glands. An essential factor for the oily skin areas is the hypersensitivity of the hormone receptors. This results in excessive oil production by the sebaceous glands.

How do hormones affect your skin?

Time course of sebaceous gland production: decrease after birth, increase with puberty, maximum circa age 25, then gradual decrease. Hormonal influences that can lead to combination skin:

Testosterone and related substances stimulate sebaceous gland production. Estrogens and antiandrogens suppress sebaceous gland production. Other causes of combination skin are:

  • Genetic stress
  • Malnutrition and malnutrition
  • Stress
  • Alcohol consumption
  • Diseases
    • Malfunction of the autonomic nervous system
    • Disorders of the adrenal cortex or ovarian function (function of the ovaries).
  • Medication use, e.g. sedatives (tranquilizers), hormone preparations.
  • External factors
    • Humid and hot weather
