Acne: Causes, Symptoms & Prevention

Acne, a common skin condition, holds significant importance today due to its widespread occurrence and impact on physical appearance and emotional well-being. It affects millions worldwide, regardless of age, gender, or ethnicity. With the increasing focus on personal appearance and the role of social media in shaping perceptions, the treatment and management of acne have become crucial in promoting self-confidence and maintaining optimal skin health. It’s the need of the hour to know more about it and learn how to manage it well.

Q. What is acne?

Ans) Acne is a common skin condition characterized by the presence of pimples, blackheads, whiteheads, and other types of lesions on the skin. It occurs when hair follicles become clogged with oil, dead skin cells, and bacteria, leading to inflammation and acne lesions.

Acne can affect people of all ages but is most prevalent during adolescence and early adulthood. During puberty, hormonal changes occur, leading to increased sebum production. The excess sebum and dead skin cells can clog pores and contribute to the development of acne. In India, acne is a significant concern as it affects a substantial portion of the population, particularly teenagers and young adults.

The impact of acne on individuals extends beyond physical symptoms, often affecting their emotional well-being and self-esteem. In a study conducted among Indian adolescents, it was found that acne had a negative psychological impact, leading to anxiety, depression, and decreased self-confidence. These emotional consequences are particularly pronounced in a society where fair and flawless skin is often associated with beauty standards.

Q. What causes acne?

Ans) Acne is a common skin condition that affects a significant portion of the Indian population, particularly adolescents and young adults. The causes of acne in India are multifactorial, resulting from hormonal, genetic, environmental, and lifestyle factors. Understanding these causes is crucial for effective management and treatment. Here are the key factors contributing to acne in the Indian population:

  • Hormonal Factors: Hormonal changes play a significant role in acne development. During puberty, there is an increase in androgen hormone production, which stimulates the sebaceous glands to produce more sebum (oil). Excess sebum production can lead to clogged pores and acne lesions. Hormonal imbalances beyond puberty, such as those associated with polycystic ovary syndrome (PCOS), can also contribute to acne development. Hormonal fluctuations during the menstrual cycle can exacerbate acne in women.
  • Genetic Predisposition: Genetic factors influence an individual’s susceptibility to acne. Studies have indicated a familial tendency for acne, suggesting a genetic component to its development. Certain genetic variations may contribute to increased sebum production, inflammation, or altered skin cell turnover, making individuals more prone to acne. However, the specific genes involved are still being studied.
  • Diet: Diet can influence acne development, and specific dietary choices have been associated with increased acne risk in the Indian population. A high glycemic index diet, rich in refined carbohydrates and sugars, has been linked to acne. Such foods cause a rapid increase in blood sugar levels, leading to hormonal fluctuations that can trigger sebum production and inflammation. Spicy and oily foods, commonly consumed in India, may also exacerbate acne for some individuals. However, the relationship between diet and acne is complex, and more research is needed to establish definitive conclusions.
  • Environmental Factors: Environmental factors prevalent in India can impact acne development. Pollution, especially in urban areas, exposes the skin to particulate matter, dust, and pollutants that can clog pores and contribute to acne breakouts. The hot and humid climate in many regions of India can increase sweating and sebum production, creating a favorable environment for acne-causing bacteria to thrive. Additionally, exposure to excessive heat and humidity can cause occlusion of the skin, leading to the formation of comedones.
  • Stress: Psychological stress has been associated with the worsening of acne in many individuals. Stress triggers the release of stress hormones, such as cortisol, which can increase sebum production and promote inflammation. Academic stress, social pressures, and lifestyle challenges in India can contribute to elevated stress levels, potentially exacerbating acne. Stress management techniques, such as exercise, relaxation techniques, and adequate sleep, can be beneficial in managing acne.
  • Skincare and Cosmetics: Improper skincare practices and certain cosmetics can contribute to acne development. Using harsh cleansers, excessive scrubbing, or not adequately removing makeup can irritate the skin, disrupt the natural balance, and lead to breakouts. Additionally, using comedogenic (pore-clogging) cosmetics or skincare products can exacerbate acne. Choosing non-comedogenic, oil-free products and adopting a gentle skincare routine is essential.

It is crucial to note that individual experiences with acne can vary, and the causes mentioned above may interact differently in each case. Consulting a dermatologist is recommended for a personalized evaluation and treatment plan.

Q. What are the symptoms of acne, and how do you treat them?

Ans) Symptoms: Acne presents with various symptoms that can vary in severity and type. The most common symptoms include:

  • Comedones (Blackheads and Whiteheads): Comedones are non-inflammatory acne lesions characterized by clogged hair follicles. Blackheads, or open comedones, appear as small, dark bumps on the skin’s surface due to the oxidation of melanin. Whiteheads, or closed comedones, are flesh-colored or slightly raised bumps when the follicle opening is blocked.
  • Papules: Papules are small, red, raised bumps on the skin. They occur when the walls of the hair follicles become inflamed. Papules are typically tender to the touch and can be sensitive.
  • Pustules: Pustules are inflamed lesions filled with pus. They appear as red bumps with a white or yellowish center. Pustules are often painful and can be accompanied by swelling and inflammation.
  • Nodules: Nodules are larger, solid, and painful acne lesions that develop beneath the skin’s surface. They occur when the hair follicles become deeply clogged, forming hard, tender nodules. Nodular acne can cause significant discomfort and has a higher risk of scarring.
  • Cysts: Cysts are severe and often painful acne lesions that are deep, pus-filled, and can cause tissue damage. They are similar to nodules but more prominent and more inflamed. Cystic acne has a higher risk of scarring and requires medical intervention for treatment.


The treatment of acne aims to control existing lesions, prevent new ones from forming, and minimize the risk of scarring. The appropriate treatment approach depends on the severity of the acne, individual factors, and any underlying conditions. It is essential to consult a dermatologist for a personalized treatment plan. Some standard treatment options include:

  • Topical Medications:

Topical medications are applied directly to the skin and can be effective for mild to moderate acne. They work by reducing sebum production, unclogging pores, and combating bacteria. Common topical treatments include:

  • Benzoyl Peroxide: It helps to kill acne-causing bacteria and reduce inflammation.
  • Topical Retinoids: These vitamin A derivatives promote skin cell turnover, prevent clogged pores, and reduce inflammation.
  • Topical Antibiotics: Antibiotics like clindamycin or erythromycin control bacterial growth on the skin.
  • Oral Medications: In cases of moderate to severe acne, oral medications may be prescribed. These medications work internally to address the underlying causes of acne. Oral medications include:
  • Oral Antibiotics: Antibiotics such as tetracycline, doxycycline, or minocycline can help control bacterial overgrowth and reduce inflammation
  • Oral Contraceptives: For women, certain oral contraceptives that contain both estrogen and progestin can help regulate hormonal imbalances and improve acne symptoms.
  • Isotretinoin: Isotretinoin is a potent oral medication used for severe acne or acne that has not responded to other treatments. It reduces sebum production, prevents clogged pores, and has long-lasting effects.
  • Procedures and Therapies: Dermatological procedures or therapies may sometimes be recommended to treat acne. These include:
  • Chemical Peels: Chemical peels involve applying a chemical solution to the skin, which exfoliates the outer layer, unclogs pores, and reduces acne lesions.
  • Laser or Light Therapy: Light-based therapies, such as laser or photodynamic therapy, can target acne-causing bacteria, reduce inflammation, and promote skin healing.
  • Extraction: Sometimes, a dermatologist may manually extract comedones, pustules, or cysts to remove the contents and reduce inflammation.
  • Skincare Practices: Adopting a consistent and gentle skincare routine is essential for managing acne. Some helpful practices include:
  • Cleansing: Cleanse the face twice daily using a mild, non-comedogenic cleanser to remove excess oil, dirt, and bacteria.
  • Moisturizing: Oil-free, non-comedogenic moisturizers keep the skin hydrated without clogging pores.
  • Avoiding Irritants: Avoid harsh skincare products, abrasive scrubs, and excessive rubbing, as they can worsen acne and irritate the skin.
  • Sun Protection: Use non-comedogenic sunscreen with a broad-spectrum SPF to protect the skin from harmful UV rays.

It is important to note that consistency and patience are essential when treating acne. Results may take time, and following the treatment plan prescribed by a healthcare professional is crucial.

Q. What will happen if acne goes untreated?

Ans) If acne goes untreated, it can have several potential consequences that can affect physical and emotional well-being. It is important to address acne early on to prevent these possible complications.

  • Scarring: One of the most significant concerns with untreated acne is the risk of scarring. Severe acne lesions, such as nodules, cysts, or deep inflammation, are more likely to result in scarring. Acne scars can be permanent and affect a person’s self-esteem and confidence. Prompt treatment can help minimize the risk of scarring and improve overall skin appearance.
  • Hyperpigmentation: Acne lesions can leave behind areas of hyperpigmentation, also known as post-inflammatory hyperpigmentation (PIH). These dark spots or patches occur due to the skin’s inflammatory response to acne. PIH can take weeks or months to fade on its own. However, treatment can help accelerate the fading process and improve skin tone.
  • Psychosocial Impact: Acne can significantly impact an individual’s psychological and emotional well-being. Untreated acne may lead to negative body image, low self-esteem, social withdrawal, and depression. Acne-related psychosocial consequences can affect interpersonal relationships, academic or professional performance, and overall quality of life.
  • Increased Inflammation and Infection: Acne is primarily caused by the colonization of Propionibacterium acnes (P. acnes) bacteria in clogged pores. The bacterial overgrowth can continue without treatment, leading to persistent inflammation and infection. This can result in the worsening of acne lesions, increased redness, pain, and new lesions.
  • Spread of Acne: Acne lesions have the potential to spread to adjacent areas if left untreated. The bacteria and inflammation can extend to surrounding follicles, creating new acne lesions. This can result in a larger affected area and increased difficulty managing the condition.
  • Secondary Infections: When acne lesions are picked, squeezed, or manipulated improperly, it can lead to secondary infections. Scratching or popping acne can introduce bacteria from the hands or nails into the skin, causing infection. Secondary infections can result in increased inflammation and pain and potentially require medical intervention.
  • Persistence of Acne: Without appropriate treatment, acne can persist for a longer duration. Acne may continue to flare up, causing recurrent breakouts and prolonging the overall time of the condition. Timely intervention can help control acne and prevent it from becoming a chronic problem.

It is important to note that the severity and course of acne can vary among individuals. While some individuals may experience mild or occasional breakouts that resolve independently, others may have more persistent or severe acne that requires professional treatment. Consulting a dermatologist is recommended for a proper evaluation and personalized treatment plan.

Q. What are the steps you can take to prevent getting acne?

Ans) Some steps you can take to prevent getting acne are as follows:

  • Maintain a Consistent Skincare Routine: Establishing a regular skincare routine is crucial for preventing acne. Follow these steps:
  • Cleansing: Cleanse your face twice daily using a gentle, non-comedogenic cleanser to remove dirt, excess oil, and impurities without stripping the skin of its natural moisture. Avoid harsh scrubbing, as it can irritate the skin and worsen acne.
  • Moisturizing: Use a lightweight, oil-free, non-comedogenic moisturizer to keep the skin hydrated without clogging the pores. Moisturizing is essential even if you have oily skin, as it helps maintain the skin’s barrier function.
  • Sun Protection: Apply a broad-spectrum sunscreen with an SPF of 30 or higher to protect your skin from harmful UV rays. Choose a non-comedogenic sunscreen specifically designed for the face.
  • Avoid Touching Your Face: Avoid touching your face frequently, as your hands can transfer dirt, bacteria, and oils to the skin. Touching or picking at acne lesions can worsen inflammation and increase the risk of scarring. If you need to connect your face, wash your hands thoroughly first.
  • Cleanse After Sweating: After exercising or sweating, cleanse your face to remove sweat, dirt, and bacteria that can clog pores and contribute to acne. Use a gentle cleanser and avoid leaving work on your skin for an extended period.
  • Use Non-Comedogenic Products: Choose skincare and cosmetic products labeled as non-comedogenic, meaning they are formulated not to clog pores. Look for oil- and fragrance-free products suitable for acne-prone skin. Avoid heavy or greasy products that can contribute to pore blockage.
  • Avoid Excessive Sun Exposure: While moderate sun exposure can benefit the skin, excessive sun exposure can lead to skin damage and worsen acne. Protect your skin from the sun and avoid tanning beds, as they can increase oil production and clog pores. If you spend time outdoors, wear protective clothing and use sunscreen.
  • Practice Proper Hair and Scalp Care: Hair products, such as gels, pomades, or oils, can contribute to acne if they come into contact with the skin. Avoid applying such products directly to the face, and be cautious when rinsing your hair, ensuring no residue comes into contact with your face. Additionally, shampoo regularly to keep your scalp clean and prevent excess oil from transferring to your face.
  • Maintain a Healthy Diet: Although the relationship between diet and acne is complex and varies among individuals, maintaining a healthy diet can support overall skin health. Include plenty of fruits, vegetables, whole grains, and lean proteins. Limit consumption of processed foods, sugary snacks, and high-glycemic-index foods, as they may exacerbate acne in some individuals.
  • Manage Stress: Stress can trigger hormonal imbalances and contribute to acne breakouts. Practice stress management techniques such as exercise, meditation, deep breathing, or engaging in activities you enjoy. Getting adequate sleep is also essential for managing stress and maintaining healthy skin.
  • Avoid Tight Clothing and Headgear: Friction and pressure from tight-fitting clothing or headgear can contribute to acne breakouts. Opt for loose-fitting, breathable clothing, and avoid wearing hats or headbands for extended periods, especially if you notice acne developing in those areas.
  • Don’t Smoke: Smoking can worsen acne and delay the healing process. Smoking restricts blood vessels, decreases the oxygen supply to the skin, and impairs its ability to regenerate. Quitting smoking or avoiding exposure to secondhand smoke can improve overall skin health.

Remember, individual responses to prevention strategies may vary, and finding a routine and approach that works best for you is crucial. If you have persistent or severe acne, it is advisable to consult a dermatologist for personalized guidance and treatment options.
