Hormone Disturbances Causing Acne

 Androgenic hormones from the testes, ovaries and the adrenal cortex are mainly responsible for the sebaceous hyperactivity in acne. Hence any diseases of these organs, medications stimulating or increasing the secretions of these hormones or drugs having similar pharmacological effects can stimulate acne production in some individuals.

Many patients with polycystic ovarian disease have moderate to severe type of acne along with unwanted hair growth. Low dose oral contraceptives are beneficial in treating acne in some female patients who show high levels of testosterone or Dehydroepiandrosterone (DHEA). Some combination pills which contain androgens could induce acne eruptions as well.

Virilization disorders where the male hormone levels are increased in females due to adrenal or ovarian growths are characterized by acne eruptions, abnormal hair growth (hirsuitism), voice changes, clitoral enlargement and increased libido.

It follows that anything irritating or further occluding the skin surface is bound to induce or aggravate acne. Oily cosmetic products like cold creams, moisturizers or oil based foundations can cause fresh acne eruptions and hence should be avoided by teens with acne prone skin.

Oil, gel or pomade applications on face could cause acne bumps to appear on the forehead, scalp or behind the neck.

Acne Inducing Medications

 Certain medications can induce acne like eruptions or exacerbate existing acne. The most common culprits are systemic and topical steroids, phenytoin, isoniazid, lithium, iodides and bromides.

In addition to the above, acne eruptions are worse in hot and humid conditions where sweating and increased sebum secretion can enhance the follicular occlusion and P.acnes proliferation. Acne has

 

also been found to be increased under stressful conditions, probably through the hormonal stimulation of the sebaceous glands.
