Can sexually transmitted diseases cause pimples?

Generally speaking, sexually transmitted diseases (STDs) refer to diseases spread through sexual contact, while pimples refer to acne. Whether sexually transmitted diseases can cause acne depends on specific circumstances. If an STD is accompanied by abnormal androgen levels, it may lead to acne; however, if the STD does not affect the endocrine system, acne typically does not develop. The detailed explanation is as follows:

Acne primarily develops due to excessive sebum production by sebaceous glands, follicular keratinization, proliferation of Propionibacterium acnes, and inflammatory responses. Certain sexually transmitted diseases, such as polycystic ovary syndrome and hyperandrogenism, are often associated with abnormal androgen levels, which may affect sebum production and thereby trigger or worsen acne symptoms. Additionally, certain medications used during the treatment of STDs, such as corticosteroids, may also increase sebum production and raise the risk of developing acne.

However, if the sexually transmitted disease does not affect the endocrine system or skin health, or if the patient maintains good skincare habits and a healthy lifestyle—including regular sleep patterns, balanced nutrition, and proper skin cleansing—then having an STD does not necessarily result in acne. Furthermore, individual skin type, genetic factors, and environmental conditions can also influence the development of acne.

In daily life, maintaining good personal hygiene and practicing safe sex can help prevent sexually transmitted diseases.
