6. <strong>Gracial</strong> and mild to<br />

moderate acne<br />

•<strong>Gracial</strong> significantly increases levels of SHBG and<br />

reduces free testosterone<br />

• These serum changes in SHBG and free testosterone<br />

result in a marked reduction in the incidence and<br />

severity of acne<br />

• The improvement in acne seen with <strong>Gracial</strong> is<br />

comparable to that seen with cyproterone acetate<br />

Androgenic skin<br />

disorders<br />

Occurrence or worsening of androgenic skin disorders is also a<br />

reason for brand switching of oral contraceptives, especially in<br />

younger women (Oddens et al 1994). This can be a<br />

consequence of the androgenicity of the progestogen<br />

component.<br />

More androgenic OCs may worsen these skin disorders (and<br />

even induce them in those previously free of such conditions).<br />

One of the underlying factors is an increased total serum<br />

testosterone and/or decreased sex hormone binding globulin<br />

(SHBG) levels, leading to an increase in free serum<br />

testosterone.<br />

In general, exogenous estrogens increase SHBG levels. As a<br />

consequence, more testosterone can be bound to SHBG,<br />

resulting in a decrease of free testosterone in the blood. This<br />

decrease of free testosterone in the blood can lead to an<br />

improvement in mild to moderate acne.<br />

6.1 Effect on SHBG and testosterone<br />

Due to its unique dosage regimen, <strong>Gracial</strong> is slightly estrogen<br />

dominant. In addition, the active progestogen component of<br />

<strong>Gracial</strong> is the most selective of the progestogens used in<br />

combined oral contraceptives. This profile suggests that<br />

<strong>Gracial</strong> has beneficial effects on acne.<br />
