What Causes Acne? Common Reasons Behind Pimples & Breakouts
Request A Call Back
  • 12 August 2026

Acne is among the most frequently reported skin problems, affecting adults and teens alike. If you've ever thought, "What causes acne?" the answer is far more complicated than just being oily. At DermoRita Skin Clinic, a trusted dermatology clinic in Delhi, we assist patients in identifying the root cause of their frequent breakouts. We also provide individual acne treatment in Delhi to help you achieve healthier, clearer skin. Whether you're experiencing frequent pimples or chronic acne, finding the root of the issue is the first step towards an effective and long-lasting solution.

What Causes Acne?

Acne occurs when hair follicles get blocked by excess oil (sebum), dead skin cells, and bacteria. The blocked pores can cause pimples, blackheads, whiteheads, cysts, or painful nodules. Although acne is usually linked to puberty, it may occur at any time due to many external and internal factors.

Understanding what causes acne can help you avoid common triggers and helps you choose the appropriate treatment programme for your complexion.

Excess Sebum Production

Sebaceous glands naturally produce sebum to keep skin moisturised and protected. However, when the glands become too active and produce excessive oil, they create a mixture that blends with dead skin cells, blocking pores.

People who have naturally oily skin types are more prone to breakouts. A key concern alongside oily skin is open pores, which can further trap sebum and bacteria, compounding the problem.

Hormones are among the most significant causes of acne. During puberty, pregnancy, menstruation, or conditions such as polycystic ovary syndrome (PCOS), androgen hormones trigger the sebaceous glands to produce more oil.

Hormonal acne is most often seen on the jawline, lower chin, and lower face in adults and could require specific acne treatment in Delhi to maintain control over time.

Bacterial Growth

A bacterium called Cutibacterium acnes naturally thrives in the pores of your skin. When pores get blocked, the bacteria multiply, leading to infection and inflammation.

This inflammatory reaction results in red pimples, swelling, and, in more severe instances, painful cystic acne. In some patients, bacterial skin concerns can also manifest as broaderskin infections that require professional dermatological evaluation.

Dead Skin Cell Build-Up

Normally, dead skin cells shed naturally from your skin's surface. However, if they build up within the pores rather than being shed correctly, they bind with oil and cause obstructions.

Regular skincare and dermatologist-recommended skin resurfacing can help reduce this problem without damaging the skin barrier.

Genetics

If your parents had acne issues, there is a greater chance you will experience it as well. Genetics affect factors like hormone production, hormone sensitivity, and inflammation responses.

While genetics cannot be changed, professional treatment can reduce acne and prevent the likelihood of breakouts in the future.

Stress and Acne

Stress is not the sole cause of breakouts; however, it can make acne more problematic. When stressed, the body releases cortisol and other hormones that increase inflammation and oil production.

Managing stress with regular exercise, adequate rest, and proper skin care can help improve the overall health of your skin.

Diet and Lifestyle Factors

Studies suggest that certain dietary habits can trigger an increase in acne in some individuals. Foods with high glycaemic levels, sugary beverages, and excessive dairy consumption can worsen acne for those with a tendency.

A balanced diet rich in fruits, vegetables, lean proteins, and whole grains helps maintain healthy skin. Drinking enough water and engaging in regular exercise are also important for overall skin health.

Cosmetic Products and Acne

Using oil-based, heavy cosmetics or skincare products that block pores can cause breakouts. Products labelled "non-comedogenic" are typically created to prevent pore blockage.

Remove makeup prior to sleeping and cleanse your face gently to minimise the chance of breakouts. Patients seeking overall improvement in skin texture and clarity may also benefit from skin toning treatments alongside targeted acne management.

Medications That May Trigger Acne

Certain medications, like corticosteroids, testosterone supplements, lithium, and anticonvulsants, may cause acne flare-ups.

If you notice a new breakout after starting a medication, talk to your doctor or dermatologist prior to making any adjustments.

Common Myths About Acne

There are many misconceptions about acne, which makes it difficult for patients to choose the best treatment. A few common myths include:

  • Acne occurs due to lack of hygiene.
  • Cleansing your face several times every day can treat acne.
  • Only teenagers get acne.
  • Toothpaste can treat pimples effectively.

In actuality, frequent cleansing can irritate the skin, and acne can affect people of all ages. Professional guidance is crucial to ensure safe and effective treatment

When Should You See a Dermatologist?

Although mild acne can be treated with over-the-counter remedies, severe or persistent acne usually requires a professional assessment. Consult with a best skin specialist in South Delhi when:

  • Acne leaves marks or dark spots.
  • Cysts or breakouts are painful.
  • Home remedies are not effective.
  • Acne impacts your confidence or mental well-being.
  • Breakouts are affecting adults, not just teenagers.

Early intervention can help prevent permanent scarring and improve treatment outcomes. If acne has already left marks, dedicated acne scar reduction treatment is available at DermoRita to restore smoother skin.
