Acne
Acne, clinically known as acne vulgaris, is a prevalent inflammatory skin condition involving the pilosebaceous units (hair follicles and oil glands). It is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and cysts. While predominantly associated with adolescence due to hormonal surges, acne frequently persists into or begins in adulthood. It is a complex disorder influenced by genetics, hormonal fluctuations, and environmental factors, often requiring a multifaceted medical approach for effective management.
Key Points
- Acne is a common, treatable skin condition affecting both teenagers and adults.
- Presents as a variety of lesions, primarily on the face, back, and chest.
- Early and appropriate treatment is crucial to prevent permanent scarring.
- Management involves a combination of medical treatments, skincare, and lifestyle adjustments.
- Treatments are highly individualized based on severity and skin type.
What is acne?
Acne is a medical dermatological condition involving the oil glands at the base of hair follicles. It occurs when these glands produce excess sebum (oil), leading to clogged pores. This environment allows Cutibacterium acnes bacteria to proliferate, resulting in inflammation and the formation of pimples or cysts.
Who gets acne?
Acne predominantly affects teenagers due to hormonal changes during puberty which stimulate oil production. However, it is not exclusive to this age group. Adults, particularly women, can experience "adult acne" related to hormonal fluctuations, stress, or certain medications.

Clinical features
Clinically, acne presents as a mix of open comedones (blackheads) and closed comedones (whiteheads), inflammatory papules, pustules, and in severe cases, deep nodules and cysts. It predominantly affects areas with a higher density of oil glands, such as the face, back, and chest. Symptoms include skin redness, tenderness, and potential scarring if left untreated.
Diagnosis and differential diagnosis
Diagnosis of acne is primarily clinical, based on the appearance of the skin. A dermatologist may consider other conditions that mimic acne to ensure the correct treatment plan is selected. These differentials can include rosacea, folliculitis, periorificial dermatitis, and facial keratosis pilaris.
Impact and complications
Acne can significantly impact quality of life, leading to reduced self-esteem, social withdrawal, and anxiety. The most significant physical complication is scarring (ice-pick, boxcar, or rolling scars) and post-inflammatory hyperpigmentation (persistent red or brown marks), which can last long after the active acne has resolved.
Causes and triggers
Genetic Influence: Family history significantly increases the risk of developing acne.
Hormones: Androgens (hormones) increase oil production, particularly during puberty and in conditions like PCOS.
Bacterial Balance: An imbalance of C. acnes bacteria on the skin drives inflammation.
Follicular Hyperkeratinisation: Dead skin cells do not shed correctly, blocking the pore.
Dietary Links: High glycemic index foods and certain dairy products (like skim milk/whey protein) may exacerbate acne in some individuals.
Stress: Stress hormones can stimulate oil glands, worsening breakouts.
Treatment Options
- Topical Treatments: Prescription retinoids (to unclog pores), Benzoyl Peroxide (to kill bacteria), and topical antibiotics or niacinamide (to reduce inflammation).
- Oral Medications Antibiotics (for inflammatory acne), Anti-androgen/Hormonal therapy (for women), or Isotretinoin (for severe, cystic, or scarring acne).
- Physical Treatments Chemical peels to exfoliate congested skin, or vascular laser to treat post-acne redness.
- Lifestyle Measures Adopting a gentle skincare routine, avoiding "picking," and modifying diet where necessary.
Frequently Asked Questions
Have questions about scheduling or what to expect? Here are answers to common inquiries to help you feel fully prepared.
Adult acne is very common, especially in women. It is often driven by hormonal fluctuations (such as those around your cycle, pregnancy, or menopause) and stress. Unlike teenage acne, adult acne often appears on the lower face and jawline and can be more stubborn to treat, often requiring a specific medical approach.
For some patients, yes. Research suggests that high-glycemic foods (sugary foods, white bread) and certain dairy products (particularly skim milk and whey protein) can trigger breakouts. We recommend a balanced, low-GI diet as a supportive measure alongside your medical treatment.
