What the Evidence Shows
The claim that taking oral natural micronised progesterone for HRT purposes such as Utrogestan could cause acne requires examining the pharmacological effects and reported side effects of this medication. Utrogestan contains micronised progesterone, which is bioidentical to the body's natural hormone.

In fact, natural progesterone has a calming, anti-androgenic effect on the skin, which can help reduce acne symptoms, as noted by expert commentary on natural progesterone's role in women's health. This contrasts with synthetic progestins that are more androgenic and more likely to cause acne and other androgen-related side effects.
However, there is some evidence that a minority of individuals may have a sensitivity or intolerance to progesterone, which can manifest as PMS-like symptoms including mood changes and acne.drlouisenewson.co.ukdrlouisenewson.co.ukProgesterone intolerance This suggests that while acne is not a common or expected side effect of micronised progesterone HRT, it can occur in susceptible individuals due to individual hormonal sensitivity. Overall, the general medical consensus and product information do not list acne as a typical side effect of Utrogestan or natural micronised progesterone.
Therefore, the claim is mostly false but acknowledges rare exceptions due to individual variation.
