Acne vulgaris develops as a result of several inter-related physiological processes occurring within the pilosebaceous unit. These include:
• Increased sebum production
• Follicular hyperkeratinisation (blockage of the hair follicle)
• Proliferation of Cutibacterium acnes
• Inflammatory and immune responses within the skin
The interaction of these factors results in the formation of comedones, papules, pustules, nodules and, in more severe cases, cystic lesions. Acne may present at any age and can be influenced by genetics, hormones, lifestyle, stress, medication and skin barrier function.
A superficial or aggressive approach to acne can worsen inflammation, compromise the skin barrier and increase the risk of long-term complications. Over-exfoliation, incorrect acid selection, inappropriate device use or failure to identify contraindications may result in:
• Persistent erythema
• Post-inflammatory hyperpigmentation (PIH)
• Acne scarring
• Barrier dysfunction and sensitivity
This is particularly important when treating clients with darker Fitzpatrick skin types, hormonal acne, or inflammatory and cystic presentations.
A thorough understanding of skin anatomy and physiology underpins safe and effective acne treatment. Practitioners must understand how the epidermis, dermis, sebaceous glands, immune system and vascular structures interact during inflammatory processes.
Knowledge of wound healing, inflammation and barrier repair is critical when planning treatment sequences, selecting products and determining appropriate treatment intervals.
Without this foundational knowledge, treatment decisions become guesswork rather than clinical judgement.
Acne treatment should be individualised, progressive and guided by thorough consultation. Common professional treatment modalities include:
Chemical Peels
When selected and applied correctly, chemical peels can help regulate keratinisation, reduce congestion and improve inflammation. Acid choice, strength, pH and treatment frequency must always be guided by skin condition rather than skin type.
Microneedling
Microneedling may be appropriate for post-acne scarring once active inflammation is controlled. Treating active acne with microneedling is contraindicated and highlights the importance of correct assessment and timing.
Advanced Peels and Skin Rejuvenation Treatments
Treatments such as BioRePeel may be used as part of a structured acne management plan, provided practitioners understand indications, contraindications and appropriate skin preparation.
Acne does not always end when active lesions resolve. Many clients experience ongoing concerns such as post-inflammatory hyperpigmentation, post-acne erythema and textural scarring.
Effective management requires an understanding of melanogenesis, inflammatory pathways and collagen remodelling, alongside careful treatment planning to avoid exacerbating pigmentation or trauma.
Acne is not a condition that can be treated with a single product, device or protocol. It requires:
• Accurate consultation and diagnosis
• Strong anatomical and physiological knowledge
• Evidence-based treatment selection
• Awareness of contraindications and scope of practice
• Ongoing professional development
For skin professionals, investing in structured acne education supports safer practice, better outcomes and increased client trust.
