Comedones during pregnancy... What to know about pregnancy-induced acne?

The gestational period is characterized by a comprehensive reorganization of a woman’s hormonal, metabolic, and immunological systems, which in turn induces a spectrum of adaptive alterations within cutaneous tissues. These physiological adaptations not only modify the progression of pre-existing dermatological conditions but also constitute a pivotal factor in the etiopathogenesis of pregnancy-specific skin disorders, collectively termed gestational dermatoses [2]. The pathogenesis of pregnancy-related acne is intrinsically linked to the dynamic fluctuations in hormonal concentrations, with progesterone—an steroid hormone synthesized in elevated quantities during gestation—assuming a predominant role. Its physiological effects encompass the amplification of sebaceous and sweat gland activity, clinically manifesting as heightened skin luminosity and accelerated sebum secretion. Androgens, a class of sex hormones to which the female body exhibits heightened sensitivity during this period, further exacerbate sebum overproduction. Concurrently, prolactin, another hormone present at elevated levels in pregnancy, contributes to the pathomechanism of acneiform eruptions. Although the precise pathophysiological underpinnings of gestational acne remain incompletely elucidated, the prevailing hypothesis posits that excessive sebum production leads to the obstruction of pilosebaceous duct orifices. Chronic irritation of these structures predisposes to the development of both non-inflammatory lesions (comedones) and inflammatory papules of varying severity [3]. The cutaneous condition is further influenced by exogenous determinants, including maternal dietary patterns, psychological stress exposure, and overall emotional equilibrium, all of which may modulate the clinical presentation and severity of symptoms.

Addressing acne during pregnancy presents a significant therapeutic challenge, necessitating a meticulous evaluation of benefits versus potential risks to both maternal and fetal health. The administration of any pharmaceutical agents—including those intended for inflammatory skin conditions—must occur strictly under medical supervision. Certain active compounds, such as oral retinoids, methotrexate, and cyclophosphamide, are categorically contraindicated due to their established teratogenic risks. Regarding over-the-counter products, a cautious approach is warranted: the absence of explicit safety information for pregnant women in the package insert should be interpreted as a contraindication. As an alternative, natural skincare methods are recommended, including alcohol-free gentle cleansers, coconut oil with antibacterial properties, and a balanced diet rich in omega-3 and omega-6 fatty acids, probiotics, and low-glycemic-index foods, which may help mitigate skin inflammation.
