Fast Facts: Acne
Introduction
Acne is one of the ten most prevalent diseases worldwide, and it is seen most often by neighbourhood physicians and dermatologists. It is classified as a chronic disease because of its long-lasting nature, tendency to flare up unexpectedly, and the negative impact it has on a person’s social well-being and mental health. Affecting individuals from infancy through adulthood, acne’s impact extends deep beneath the skin’s surface, often causing significant psychological distress, social isolation, and permanent scarring.
The second edition of Fast Facts: Acne provides a concise yet comprehensive overview for healthcare professionals, demystifying the pathophysiology of acne and translating the latest evidence into practical, effective management strategies. This guide underscores the critical importance of recognizing acne as a serious medical condition requiring timely and targeted intervention to mitigate both its physical and emotional sequelae.
Treatments for Acne
The management of acne requires a sophisticated, multi-faceted approach tailored to the individual’s clinical presentation. The cornerstone of treatment involves targeting the four key pathogenic factors: sebum production, follicular hyperkeratinization, Propionibacterium acnes colonization, and inflammation. For mild cases, topical therapies like retinoids and benzoyl peroxide (BPO) are first-line, with combination products enhancing efficacy and adherence. Moderate-to-severe inflammatory acne often necessitates a course of systemic antibiotics, but a critical modern guideline is to never use them as monotherapy; they must be combined with BPO to prevent the alarming rise of global antibiotic resistance.
For severe, scarring, or treatment-resistant cases, oral isotretinoin remains the most effective treatment, offering lasting remission by uniquely affecting all four pathogenic pathways. Furthermore, hormonal therapies are a vital option for women, while adjunct physical treatments address persistent scars. Ultimately, successful management hinges on careful agent selection, patient education, and a treatment pathway that evolves from initial control to long-term maintenance, primarily with topical retinoids.

Some questions frequently asked by patients:
Question: Is acne caused by poor diet?
-
- Answer: There is no direct evidence to support this. In general, acne is not made worse by any specific foods but epidemiological studies suggest a possible link with intake of skim milk. Limited data suggest that a diet with low glycemic load may improve acne
Question: Is acne caused by bad hygiene?
-
- Answer: Frequent washing has no effect on acne; most people wash too much
Question: Can I wear cosmetics?
-
- Answer: There is no evidence that cosmetic usage makes acne worse; however, greasy cosmetics should be avoided. Oil-free or non-comedogenic preparations are available.
Question: Should I exercise more?
-
- Answer: Exercise does not influence acne, but sweating around bra straps or waistbands can cause follicular inflammation.
Question: Does stress aggravate acne?
-
- Answer: Stress can aggravate acne. Conversely, acne can cause stress
Question: Does acne flare before a period?
-
- Answer: A premenstrual acne flare occurs in about 60% of women with acne
Question: Does sunshine help?
- Answer: Sun exposure is reported to have a beneficial effect in up to 70% of patients with acne, but the effects are short lived. Sunscreens are important, as the sun can exacerbate facial irritation from topical acne medications and some topical preparations make patients more photosensitive.
Question: Should I stop wearing moisturizer?
- Answer: Most moisturizers from reputable companies are tested for comedogenicity in clinical trials and are labeled ‘noncomedogenic’. Some topical treatments dry the skin, so regular use of moisturizers is especially important. Moisturizers do not alter efficacy of treatments.
Question: Does smoking have an effect on acne?
- Answer: The relationship between acne and smoking is not yet clear. Smoking seems to induce closed comedones in adult women.
Question: Does exercise affect acne?
- Answer: Substances with androgenic potential can be found in products used by athletes
Conclusion
In conclusion, Fast Facts: Acne positions acne as a chronic disease demanding a proactive, informed, and holistic management strategy. The guide moves beyond mere treatment protocols, emphasizing the necessity of early intervention to prevent scarring, the imperative of combating antibiotic resistance through rational prescribing, and the critical need to address the profound psychosocial burden carried by patients. By integrating a clear understanding of acne’s etiology with evidence-based therapeutic options—from topicals and systemics to hormonal and physical treatments—clinicians can significantly improve patient outcomes. The ultimate goal is not only to clear the skin but also to restore the patient’s quality of life, affirming that effective acne management is a vital component of overall health and well-being.
