Hormones and acne treatment
The development
and secretory activity of the skin's sebaceous gland are unquestionably
under control of hormones and any means to manipulate this control
could be of immediate importance in acne treatment. Human skin is
a collection of androgen-responsive tissues, hair follicles, sebaceous
glands, sweat glands, epidermis, dermis. Many practitioners and
patients with adult acne believe that stress exacerbates the condition,
delays the course of acne treatment and skin clarification. Since
adrenocoticotropic hormone (ACTH) is produced in response to stress,
some researchers have focused on its possible role in the development
of adult acne. According to Toyoda et al there is ample clinical
evidence suggesting that the nervous system such as emotional stress
can influence the course of acne. Adrenal gland dysfunction may
be present in some patients with acne, particularly when there is
associated hirsutism, abnormal menses and infertility. Androgen
serum levels are normal in most adult patients with acne suggesting
that hypersensitivity of androgen receptors in pilosebaceous duct
may be associated with development of adult acne. Although, according
to Carmina et al serum androsterone glucuronide (AoG) is a metabolite
of circulating androgens under the influence of 5alpha-reductase
activity and has been shown to be particularly elevated in adult
women with acne. Their study suggests that serum AoG is a sensitive
marker of acne in women.
The involvement
of hormones especially androgens in development of hormonal acne
suggests use of anti androgens to clear the skin from acne. However
this approach sounds logical, normal serum androgens in most acne
patients undermine the hypothesis. Hypersensitivity of androgen
receptors in follicular ducts is another way to explain the role
of androgens in adult acne. Theraputics with hormones provide valuable
alternatives to standard adult acne treatments in selected individuals
when there is evidence of hyperandrogenism.
In contrast, female hormones, estrogens and progestrone help clear the skin and sometimes are used in treatment of acne. Birth control pills does not cause acne and their use is associated with overall skin texture improvement. Birth control pills could be either combinations of estrogen and progestrone or each hormone by itself.
