Causes Of Acne

Acne is caused when tiny holes in the skin, known as hair follicles, become blocked.

  • a. Sebaceous glands are tiny glands found near the surface of your skin, which produce sebum.
  • b. In acne, the glands begin to produce too much sebum.
  • c. The excess sebum mixes with dead skin cells and both substances form a plug in the follicle.
  • d. If the plugged follicle is close to the surface of the skin, it will bulge outwards, creating a whitehead.
  • e. Alternatively, the plugged follicle can be open to the skin, creating a blackhead.
  • f. Normally harmless bacteria that live on the skin can then contaminate and infect the plugged follicles, causing papules, pustules, nodules or cysts.
  • Testosterone

    Teenage acne is thought to be triggered by increased levels of a hormone called testosterone, which occurs during puberty.
    The sebaceous glands are particularly sensitive to hormones.
    It is thought that increased levels of testosterone cause the glands to produce much more sebum than the skin needs.

    Acne in families

    Acne can run in families. If your parents had acne, it’s likely that you will also develop it.

    Acne in women

    More than 80% of cases of adult acne occur in women. It is thought that many cases of adult acne are caused by the changes in hormone levels that many women have at certain times.

    These times include:

    Periods: Some women have a flare-up of acne just before their period

    Pregnancy: Many women have symptoms of acne in pregnancy, usually during the first three months of their pregnancy

    Polycystic ovary syndrome (PCOS): A common condition that can cause acne, weight gain and the formation of small cysts inside the ovary

    Other triggers

    Other possible triggers of an acne flare-up include:

  • Some cosmetic products
  • Certain medications, such steroids or anti-epileptic drugs
  • Regularly wearing items that place pressure on an affected area of skin, such as a headband or backpack
  • Smoking can contribute to acne in older people
