I am 29 years old male. I was prescribed azelaic acid 20% and deriva bpo last year. I applied it for few months and left in winters. Now again I started having breakout in april month I am using deriva bpo since then. I do not get breakouts while I am using it. I start getting breakouts if I stop it. Its been 5 months should I keep applying it or stop it.

Pimples, also known as acne, are primarily caused by a combination of factors involving the skin's oil glands, hair follicles, bacteria, and hormonal changes. Here are some of the common causes of pimples: 1. Excessive sebum production: sebum is an oily substance produced by the sebaceous glands in the skin. When the sebaceous glands produce too much sebum, it can clog the hair follicles, leading to the formation of pimples. 2. Clogged pores: the hair follicles or pores can become clogged with dead skin cells, dirt, and other debris. When this happens, it creates an environment where bacteria can thrive, causing inflammation and resulting in pimples. 3. Bacterial activity: the skin is home to bacteria, including propionibacterium acnes (p. Acnes). This bacterium feeds on the sebum produced by the skin and can multiply rapidly in clogged hair follicles, leading to inflammation and the formation of pimples. 4. Hormonal changes: hormonal fluctuations, particularly during puberty, menstruation, pregnancy, and menopause, can increase sebum production and alter the normal functioning of the skin. This hormonal imbalance can contribute to the development of pimples. 5. Diet: while the relationship between diet and acne is not fully understood, some studies suggest that certain foods, such as high-glycemic-index carbohydrates and dairy products, may worsen acne in susceptible individuals. However, more research is needed to establish definitive links. 6. Stress: stress can aggravate acne or contribute to its development. High-stress levels may increase inflammation in the body, leading to acne flare-ups. 7. Medications: some medications, such as corticosteroids, androgenic steroids, and certain anticonvulsants, may cause acne as a side effect. 8. Cosmetic products: certain makeup, skincare products, and hair styling products that are comedogenic (tend to clog pores) can contribute to the development of pimples. It's important to note that the causes and severity of acne can vary from person to person, and treating acne effectively often requires a tailored approach based on individual factors. If you're experiencing persistent or severe acne, it's advisable to consult a dermatologist for proper diagnosis and treatment.
