Acne vulgaris affects approximately 95% of people aged 11-30 and persists into adulthood for up to 50% of individuals. Despite being the most common skin condition globally, effective treatment remains challenging — particularly when balancing efficacy against irritation, scarring risk, and long-term skin health.

The Pathophysiology of Acne

Acne develops through four interconnected mechanisms:

1. Excess sebum production — Driven by androgens and genetic predisposition

2. Follicular hyperkeratinisation — Abnormal shedding of dead cells within the follicle creates a plug (microcomedone)

3. Bacterial proliferation — Cutibacterium acnes thrives in the anaerobic environment of blocked follicles

4. Inflammation — Bacterial metabolites trigger an immune response, producing papules, pustules, and nodules

Effective treatment must address multiple pathways simultaneously.

Medical-Grade Active Ingredients for Acne

Salicylic Acid (BHA)

Oil-soluble beta hydroxy acid that penetrates into the follicle to dissolve the keratin plug. At 0.5-2% in daily products and up to 30% in professional peels. The gold standard comedolytic ingredient.

Niacinamide

Reduces sebum production by up to 23% at 2-4% concentration while providing anti-inflammatory benefits without irritation. An ideal ingredient for acne-prone skin of all types.

Retinoids

Medical-grade retinol normalises follicular keratinisation, preventing microcomedone formation. Prescription retinoids (adapalene, tretinoin) offer stronger comedolytic action. Essential for maintenance therapy.

Mandelic Acid (AHA)

Larger molecular size means slower, more even penetration — making it suitable for sensitive and darker skin types where other AHAs may cause PIH. Antibacterial properties complement its exfoliating action.

Azelaic Acid

Dual-action ingredient: anti-bacterial against C. acnes and anti-inflammatory. Also inhibits tyrosinase, making it particularly valuable for acne patients with concurrent hyperpigmentation.

Professional Treatment Protocol

Mild Acne (Comedonal)

AM: Blemish cleanser → Niacinamide serum → Oil-free moisturiser → SPF 50

PM: Blemish cleanser → Salicylic acid treatment → Retinol 0.25% (alternate nights)

Monthly: Professional salicylic or mandelic peel

Moderate Acne (Inflammatory)

AM: Gentle cleanser → Niacinamide 5% → Azelaic acid 15% → SPF 50

PM: Blemish cleanser → Blemish serum → Retinol 0.5%

Bi-weekly: Professional peels (mandelic 30% + salicylic 10%)

Monthly: EXO OX Clear exosome treatment for anti-inflammatory regeneration

Severe/Scarring Acne

Refer for dermatological assessment (isotretinoin consideration)

Post-isotretinoin: maintenance retinol + barrier support

Scarring: microneedling with exosome serum for collagen remodelling

PIH: depigmentation treatments

Common Mistakes in Acne Treatment

Over-cleansing — Stripping the barrier triggers compensatory sebum production. Cleanse twice daily maximum

Skipping moisturiser — Even oily, acne-prone skin needs hydration. Use oil-free, non-comedogenic formulas

Too many actives simultaneously — Introduce one new active at a time, allowing 2-4 weeks for acclimatisation

Stopping treatment when skin clears — Acne requires ongoing maintenance to prevent recurrence

Ignoring SPF — Many acne actives increase photosensitivity. SPF 50 is essential to prevent PIH

The Role of Exosomes in Acne Treatment

EXO OX Clear represents a novel approach to inflammatory acne, delivering anti-inflammatory exosome cargo directly to the treatment area. Clinical applications include:

Reducing active inflammation without antibiotics

Accelerating healing of acne lesions

Preventing and treating post-acne scarring

Normalising the skin microbiome environment

Frequently Asked Questions

Can adults develop acne for the first time?

Yes. Adult-onset acne is increasingly common, particularly in women aged 25-50. Hormonal fluctuations, stress, and lifestyle factors contribute. The treatment approach is similar but with greater emphasis on barrier-gentle formulations and hormonal assessment.

Does diet affect acne?

Emerging evidence links high-glycaemic diets and dairy consumption to acne in susceptible individuals. While not the primary cause, dietary modification can complement topical treatment for some patients.

When should I refer to a dermatologist?

Refer when: acne is severe/nodulocystic, there is a scarring risk, topical treatments have been tried for 3+ months without improvement, or the patient is considering isotretinoin.
