Persistent Acne on One Side: Is It a Sign of Underlying Issues?

Recurrent acne?

Hello Doctor: I have acne only on the left side of my face, and there are no whiteheads, just red, swollen bumps that are painful to touch.
The medication prescribed by the doctor seems to be causing more breakouts, and they keep spreading, always appearing in the same area.
Does this indicate that there might be an issue with a certain function in my body?

No.
Pay attention to whether there is frequent friction in that area or if you tend to sleep on that side.

Persistent acne localized to one side of the face can indeed raise concerns about underlying issues, although it is essential to approach this topic with a comprehensive understanding of dermatological health and potential systemic factors.
Acne is primarily caused by the overproduction of sebum, clogged pores, bacteria, and inflammation. However, when acne appears persistently on one side of the face, it can suggest a few different possibilities. One common explanation is that it may be related to external factors such as friction, pressure, or irritation from items that frequently touch that side of the face. For example, if you tend to rest your face on your hand, use a phone on that side, or wear hats or helmets that press against the skin, these could contribute to localized acne.

Another consideration is hormonal imbalances. Hormonal fluctuations can lead to increased oil production and acne formation. Conditions such as polycystic ovary syndrome (PCOS) can cause hormonal acne, often presenting on the lower face and jawline. If your acne is accompanied by other symptoms such as irregular menstrual cycles, weight gain, or excessive hair growth, it may be worth discussing hormonal evaluations with your healthcare provider.

Additionally, persistent acne on one side could indicate an underlying skin condition, such as rosacea or folliculitis, which may require different treatment approaches than typical acne. It is also crucial to consider dietary factors, as certain foods can exacerbate acne in some individuals. For instance, high-glycemic foods, dairy, and certain fats may contribute to acne flare-ups.

If the medication prescribed by your doctor is causing an increase in acne, it may be a sign that the treatment is not suitable for your specific skin type or condition. Some topical treatments can lead to irritation or purging, where existing comedones come to the surface, making it seem like the acne is worsening. It is essential to communicate with your healthcare provider about your concerns and the response to the treatment you are receiving. They may need to adjust your treatment plan or explore alternative therapies, such as topical retinoids, benzoyl peroxide, or even oral medications if necessary.

In conclusion, while persistent acne on one side of the face can indicate underlying issues, it is crucial to evaluate all potential contributing factors, including lifestyle, hormonal health, and treatment responses. A thorough assessment by a dermatologist or healthcare provider can help identify the root cause and guide you toward effective treatment options. If you have not already, consider seeking a second opinion or consulting a dermatologist who specializes in acne and skin disorders for a more tailored approach to your condition.
