For trans men, transmasculine and nonbinary people who choose medical transition with testosterone, this treatment can sometimes lead to acne breakouts on the face or body. Testosterone has been found to causes increased skin production of sebum in trans men, which is a factor in the development of acne (Giltay & Gooren, 2000), and the Endocrine Society (Hembree et al., 2017) and the World Professional Association for Transgender Health (Coleman et al., 2012) have noted that acne can begin to develop as soon as one month after starting HRT.
Acne can represent a significant burden for trans people taking testosterone: Wierckx et al. (2014) reported that after 6 months of treatment, 82.4% of trans men developed facial acne and 88.2% experienced acne on their chest or back, and half of the participants in the study began using acne treatments such as topical benzoyl peroxide or oral antibiotics. Notably, Motosko et al. (2019) found that 52% of trans men on testosterone in their study sample experienced acne, compared to only 6.7% of cis men. Higher levels of testosterone also appear to be associated with a greater likelihood of developing acne (Park et al., 2019). Continue reading
