Acne, a common skin condition, occurs when hair follicles become clogged with a combination of oily sebum and dead skin cells. This results in the formation of whiteheads, blackheads, pimples, and other unsightly blemishes. Although there is a plethora of misinformation circulating about acne, having a clear understanding of its actual causes can greatly aid in its prevention.
Genes and Acne Development
The role of genes in the development of acne is undeniable. Acne is highly heritable, although its inheritance pattern is somewhat peculiar. Studies have revealed that acne susceptibility is influenced by multiple genes, making it a polygenic condition. Moreover, certain genetic disorders, such as Apert’s syndrome, have been found to be associated with acne as well.
How Hormones Can Influence Acne
Hormonal changes play a significant role in the development of acne. Various life events, such as puberty, menstrual cycles, and pregnancy, can lead to hormonal shifts that trigger breakouts.
During puberty, an increase in androgens, a group of hormones including testosterone, stimulates the growth of hair follicle glands and enhances sebum production. The excess sebum then combines with dead skin cells, clogging the pores and resulting in acne. This suggests that androgen hormones are crucial for acne formation, as individuals with complete androgen insensitivity syndrome do not experience acne.
