Acne Treatment Pathways — From Mild to Severe

Last updated: 5 March 2026

Understanding Acne: More Than Just Spots

Acne is the most common skin condition in the United Kingdom affecting approximately 95 percent of people aged 11 to 30 to some degree. Yet despite its prevalence acne remains widely misunderstood and frequently undertreated. At Axiom Aesthetics, we take acne seriously offering evidence-based treatment pathways tailored to the type and severity of each patient’s condition.

The Pathophysiology of Acne

Four Key Factors

Acne develops through the interplay of four primary factors: excess sebum production driven by hormonal influences, follicular hyperkeratinisation where dead skin cells block the pore, bacterial colonisation by Cutibacterium acnes, and inflammation as the immune system responds to bacterial metabolites and follicular rupture.

Types of Acne Lesions

Non-inflammatory lesions include open comedones (blackheads) and closed comedones (whiteheads). Inflammatory lesions include papules, pustules, nodules, and cysts which carry the highest risk of scarring.

Grading Acne Severity

Mild: Predominantly non-inflammatory with scattered comedones and occasional papules. Moderate: A mix of comedones and inflammatory lesions affecting the face and potentially the back and chest. Moderately Severe: Widespread inflammatory lesions with some nodules. Severe: Dominated by nodules and cysts often with scarring already present.

Treatment Pathway: Mild Acne

First-Line Topical Treatments

Benzoyl peroxide at 2.5 to 10 percent works as an antibacterial agent, comedolytic, and anti-inflammatory. Topical retinoids such as adapalene address the root cause of comedone formation. Azelaic acid at 15 to 20 percent combines antibacterial, anti-inflammatory, and anti-pigmentation properties and is particularly useful for patients with darker skin tones.

Treatment Pathway: Moderate Acne

Combination Topical Therapy

The most evidence-based combinations include benzoyl peroxide plus a topical retinoid, benzoyl peroxide plus a topical antibiotic, and a retinoid plus antibiotic combined with benzoyl peroxide.

Clinical Treatments

Chemical peels using salicylic acid or glycolic acid help clear comedones and reduce inflammation. LED blue light therapy targets C. acnes bacteria without antibiotics. At Axiom Aesthetics we offer tailored clinical programmes for moderate acne.

Treatment Pathway: Severe Acne

Oral Medications

Oral antibiotics such as lymecycline or doxycycline reduce bacterial populations and inflammation. Hormonal therapies may be appropriate for female patients. For severe or treatment-resistant acne isotretinoin remains the most effective treatment available addressing all four pathogenic factors simultaneously.

Advanced Clinical Treatments

Microneedling creates controlled micro-injuries stimulating collagen production for acne scar improvement. Medium-depth chemical peels can improve both textural scarring and hyperpigmentation. Various laser technologies including fractional CO2 and pulsed dye lasers address different aspects of acne scarring.

The Role of Diet and Lifestyle

High glycaemic index foods appear to worsen acne by increasing insulin and IGF-1. Dairy products particularly skimmed milk have been associated with increased acne severity. Chronic stress increases cortisol production which can worsen acne through increased sebum production and impaired immune function.

When to Seek Professional Help

Professional guidance becomes important when over-the-counter treatments have not improved symptoms after eight to twelve weeks, acne is moderate or severe, scarring is developing, or acne is significantly affecting mental health. Our experienced team at Axiom Aesthetics can assess your acne and create a comprehensive plan.

Frequently Asked Questions

How long does acne treatment take to work?

Most treatments require six to twelve weeks of consistent use. Some treatments particularly retinoids may cause temporary worsening before improvement.

Will my acne come back after treatment?

With the exception of isotretinoin which can achieve long-term remission most treatments manage rather than cure the condition. A maintenance regimen is usually necessary.

Can adults get acne?

Absolutely. Adult acne is increasingly common particularly among women due to hormonal fluctuations, stress, and environmental factors.
