Abstract
Cortisol is involved in the distribution and deposition of fat, and its action is regulated by the activity of 11β-hydroxysteroid dehydrogenase.
Glycyrrhetinic acid, the active principle of licorice root, blocks 11β-hydroxysteroid dehydrogenase type 1, thus reducing the availability of cortisol at the level of adipocytes.
We evaluated the effect of topical application of a cream containing glycyrrhetinic acid in the thickness of fat at the level of the thigh.
Eighteen healthy women (age range 20–33 years) with normal BMI were randomly allocated to treatment, at the level of the dominant thigh, with a cream containing 2.5% glycyrrhetinic acid (n = 9) or with a placebo cream containing the excipients alone (n = 9). Before and after 1 month of treatment both the circumference and the thickness of the superficial fat layer of the thighs (by ultrasound analysis) were measured.
The circumference and the thickness of the superficial fat layer were significantly reduced in comparison to the controlateral untreated thigh and to control subjects treated with the placebo cream.
No changes were observed in blood pressure, plasma renin activity, plasma aldosterone or cortisol.
The effect of glycyrrhetinic acid on the thickness of subcutaneous fat was likely related to a block of 11β-hydroxysteroid dehydrogenase type 1 at the level of fat cells; therefore, glycyrrhetinic acid could be effectively used in the reduction of unwanted local fat accumulation

Ja myös B. Stallknechtin ja kumppaneitten tutkimus ('Are blood flow and lipolysis in subcutaneous adipose tissue influenced by contractions in adjacent muscles in humans' American Journal of Physiology, 2006 ) viittaa, että 'spot reduction' olisi mahdollista.

Abstract
Objective: Topical fat reduction from the thigh in women using aminophylline cream has been demonstrated, but the local fat reduction in other body areas or in men by lowering the local lipolytic threshold has not been demonstrated. This study is designed to test the hypothesis that aminophylline cream application to the waist will reduce waist circumference compared with a control.
Research methods and procedures: Fifty men and women who are 21–65 years of age with a BMI greater than 27 kg/m2 and a waist to hip ratio ≥average were randomized in a 1 : 1 ratio to 0.5% aminophylline cream to the waist twice a day or no treatment to the waist. All subjects were instructed to follow a 1200 kcal balanced diet, participate in a walking program and return biweekly to encourage compliance. A theophylline level was drawn monthly, and the waist, BMI and waist to hip ratio were remeasured at 12 weeks.
Results: At week 12, there was a significant reduction in BMI from baseline that was not different between the groups. The reduction in waist circumference was 11 ± 1.0 cm in the aminophylline cream group and 5.0 ± 0.6 cm in the control group (p < 0.001). The reduction in waist circumference was significant for both women and men, but the women lost significantly more waist girth. The waist to hip ratio, a measure of fat distribution, declined. Aminophylline levels were undetectable, and there were no adverse events.
Discussion: Aminophylline cream offers a safe and effective method for cosmetic local fat reduction from the waist.
