    Although the causes of baby acne are not fully understood, there are currently several factors that predispose infants to develop this type of skin lesions.

    • Hormonal disorders – increased levels of androgens (including maternal hormones, which the infant receives in breast milk, and hormones produced by the child’s adrenal glands) stimulate the sebaceous glands to overproduce sebum. 
    • Bacterial colonization Propionibacterium acnes – this is a bacterium that naturally occurs on the skin, but in infants it can overgrow, leading to inflammation of the hair follicles and the formation of blackheads and purulent pimples in an infant.
    • Immaturity of infant skin - is one of the possible causes of baby acne. Babies' skin physiologically produces more sebum, which contributes to the clogging of pores and the formation of so-called pimples.
    • Inadequate care – the use of cosmetics containing mineral oils, such as paraffin or petroleum jelly, may intensify skin lesions and be one of the causes of baby acne, exacerbating its symptoms.
