Acne is a common skin condition that affects people of all ages, though it is most prevalent among teenagers and young adults. It occurs when hair follicles become clogged with oil and dead skin cells, leading to whiteheads, blackheads, pimples, and cystic lesions.
While acne is not life-threatening, it can cause emotional distress, low self-esteem, and permanent scarring if left untreated. Fortunately, there are numerous effective treatments available to help manage and reduce acne.

Understanding Acne And Its Causes
Acne develops due to several factors, including excess oil production, clogged pores, bacteria, and inflammation. Hormonal changes, diet, stress, genetics, and certain medications can also contribute to acne flare-ups. The severity of acne varies from mild (occasional pimples) to severe (painful cysts and nodules), requiring different treatment approaches.
Topical Treatments For Acne
Benzoyl Peroxide
Benzoyl peroxide is a widely used over-the-counter treatment for acne. It works by killing acne-causing bacteria and reducing inflammation. Available in various concentrations (2.5% to 10%), benzoyl peroxide can be found in gels, creams, and cleansers. While effective, it may cause dryness, peeling, and irritation, so it is best to start with a lower concentration and gradually increase usage.
Salicylic Acid
Salicylic acid is another common ingredient in acne treatments. It exfoliates the skin, unclogs pores, and reduces swelling and redness. Salicylic acid is suitable for mild to moderate acne and is available in face washes, toners, and spot treatments. Regular use can help prevent breakouts and improve overall skin texture.
Retinoids
Topical retinoids, such as adapalene, tretinoin, and tazarotene, are derivatives of vitamin A that promote cell turnover and prevent clogged pores. Retinoids are highly effective for treating acne but may cause initial irritation, dryness, and increased sun sensitivity. Using a moisturiser and sunscreen can help mitigate these side effects.
Antibiotics
Topical antibiotics, such as clindamycin and erythromycin, help reduce bacteria and inflammation. They are often combined with benzoyl peroxide to prevent antibiotic resistance. These treatments are best suited for moderate acne and should be used under the guidance of a healthcare professional.
Azelaic Acid
Azelaic acid is a naturally occurring acid that has antibacterial and anti-inflammatory properties. It is effective in treating acne, reducing redness, and improving skin tone. Azelaic acid is a good option for those with sensitive skin as it is generally well tolerated.
Oral Medications For Acne
Antibiotics
Oral antibiotics, such as doxycycline, minocycline, and erythromycin, are prescribed for moderate to severe acne. They help reduce inflammation and kill acne-causing bacteria. Since prolonged use can lead to antibiotic resistance, they are typically prescribed for short-term use alongside topical treatments.
Oral Contraceptives
For women with hormonal acne, oral contraceptives can be an effective treatment. Certain birth control pills containing oestrogen and progestin help regulate hormone levels, reducing acne breakouts. It is essential to consult a doctor to determine the most suitable contraceptive option.
Isotretinoin (Accutane)
Isotretinoin is a powerful oral retinoid used for severe cystic acne that has not responded to other treatments. It reduces oil production, prevents clogged pores, and decreases inflammation. While highly effective, isotretinoin has potential side effects, including dry skin, chapped lips, and, in rare cases, depression. Due to its potency, it requires close medical supervision and regular blood tests.
Lifestyle And Skincare Tips For Acne Management
Gentle Cleansing
Washing the face twice daily with a mild, non-comedogenic cleanser helps remove excess oil and impurities. Avoid scrubbing the skin harshly, as this can worsen irritation and inflammation.
Moisturising
Using an oil-free, non-comedogenic moisturiser keeps the skin hydrated without clogging pores. Moisturising is especially important for those using acne treatments that may cause dryness.
Sun Protection
Many acne treatments, including retinoids and benzoyl peroxide, increase sun sensitivity. Wearing a broad-spectrum sunscreen with SPF 30 or higher helps protect the skin from UV damage and prevents post-inflammatory hyperpigmentation.
Avoiding Picking And Squeezing
Picking or squeezing pimples can lead to scarring and further inflammation. It is best to allow pimples to heal naturally or use targeted treatments to speed up the process.
Healthy Diet
While research on the link between diet and acne is ongoing, some studies suggest that high-glycaemic foods and dairy products may contribute to breakouts. Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can support overall skin health.
Stress Management
Stress can trigger acne flare-ups by increasing hormone levels that stimulate oil production. Engaging in stress-relieving activities such as exercise, meditation, and adequate sleep can help manage acne.
Natural And Alternative Treatments
Tea Tree Oil
Tea tree oil has antimicrobial and anti-inflammatory properties that can help reduce acne. It is a natural alternative to benzoyl peroxide, but it should be diluted before application to avoid irritation.
Green Tea Extract
Green tea contains antioxidants and anti-inflammatory compounds that may help reduce sebum production and acne severity. Applying green tea extract topically or drinking green tea regularly can be beneficial.
Aloe Vera
Aloe vera is known for its soothing and anti-inflammatory properties. Applying aloe vera gel to acne-prone skin can help calm redness and irritation.
Zinc Supplements
Zinc is an essential mineral that supports immune function and reduces inflammation. Some studies suggest that taking zinc supplements can improve acne symptoms, particularly for those with a deficiency.
When To See A Dermatologist
If over-the-counter treatments and home remedies do not provide relief, or if acne is severe and causing scarring, it is best to consult a dermatologist. A skincare professional can assess the condition, recommend appropriate treatments, and prescribe stronger medications if needed.
Conclusion
Acne is a multifactorial skin condition that requires a personalised approach to treatment. From topical and oral medications to lifestyle adjustments and natural remedies, there are numerous ways to manage acne effectively.
Understanding the underlying causes and selecting the right treatments can help achieve clearer skin and improved confidence. For persistent or severe cases, seeking professional guidance is recommended to prevent complications and achieve the best results.
Frequently Ask Question
Can Stress And Lack Of Sleep Cause Acne?
Stress and lack of sleep can contribute to acne flare-ups by increasing cortisol levels, which can stimulate oil production and inflammation. Chronic stress may also weaken the skin’s barrier, making it more prone to breakouts. Prioritising stress management through exercise, meditation, and relaxation techniques can help improve skin health.
Ensuring at least 7–9 hours of quality sleep per night supports skin regeneration and reduces inflammation. While stress alone doesn’t cause acne, managing it can help prevent worsening breakouts.
Do Acne Scars Fade On Their Own?
Mild post-acne marks, such as red or brown spots, can fade over time, but deeper scars may require treatment. Chemical peels, microneedling, and laser therapy can help improve the appearance of acne scars. Retinoids and vitamin C serums can also promote skin renewal and fade pigmentation.
Sun protection is crucial, as UV exposure can worsen the appearance of scars. Consulting a dermatologist can help determine the best treatment option based on scar type and severity.
How Long Does It Take For Acne Treatments To Work?
Most acne treatments take at least 6–8 weeks to show noticeable improvements. OTC products with benzoyl peroxide or salicylic acid may work within a few weeks for mild acne, while prescription treatments like retinoids can take several months. Isotretinoin treatment usually lasts 4–6 months, with results often continuing after stopping the medication.
Consistency is key—switching treatments too frequently can irritate and delay results. If there’s no improvement after 12 weeks, a dermatologist should be consulted for alternative options.
