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 />
