Lesson 2 • Skin Structure and Function Review

Covers epidermis, dermis, and appendage anatomy relevant to acne. Provides the anatomical baseline for all subsequent pathology discussions.

Lesson 3 • Sebum Production and Regulation

Explains sebocyte biology, lipid composition of sebum, and hormonal regulation. Links excess sebum to comedone formation and inflammation.

Lesson 4 • Follicular Keratinisation and Comedone Formation

Details abnormal keratinocyte shedding that obstructs follicles and initiates microcomedones. Connects keratinisation defects to visible lesion development.

Lesson 5 • Acne Classification and Grading Systems

Introduces standardised grading scales and lesion morphology terminology used in clinical assessment. Enables consistent documentation and treatment benchmarking.

Lesson 1 • Medication-Induced and Occupational Acne

Reviews drug classes and workplace exposures that trigger acneiform eruptions. Differentiates drug-induced acne from primary acne vulgaris.

Lesson 2 • Dietary and Metabolic Triggers

Examines evidence linking high-glycaemic foods, dairy, and insulin resistance to acne severity. Connects metabolic pathways to follicular and sebaceous activity.

Lesson 3 • Psychological Stress and Neuroendocrine Pathways

Explains how chronic stress activates the hypothalamic-pituitary-adrenal axis to worsen acne. Establishes the rationale for stress management in treatment plans.

Lesson 4 • Topical and Environmental Triggers

Identifies comedogenic ingredients, occlusive products, pollution, and humidity as external acne drivers. Guides product selection and environmental counselling.

Lesson 1 • Treatment Goal Setting and Benchmarking

Guides practitioners in setting realistic, measurable treatment goals with clients. Establishes progress tracking methods aligned with grading systems.

Lesson 2 • Technology-Assisted Skin Analysis

Introduces Wood's lamp, digital imaging, and sebumeter tools for objective skin assessment. Enhances diagnostic precision and client communication.

Lesson 3 • Visual and Manual Skin Analysis Techniques

Teaches systematic visual inspection and palpation methods to identify lesion types and distribution. Builds tactile and observational diagnostic accuracy.

Lesson 4 • Differential Diagnosis of Acne-Like Conditions

Distinguishes acne vulgaris from rosacea, perioral dermatitis, folliculitis, and milia. Prevents misdiagnosis and inappropriate treatment application.

Lesson 1 • Anti-Inflammatory and Sebum-Regulating Actives

Covers niacinamide, zinc, green tea, and willow bark for inflammation and sebum control. Supports formulation of calming, multi-action treatment regimens.

Lesson 2 • Keratolytic and Exfoliating Agents

Covers salicylic acid, glycolic acid, and lactic acid mechanisms in normalising keratinisation. Connects exfoliant selection to comedone type and skin sensitivity.

Lesson 3 • Retinoids in Acne Management

Explains retinol, retinaldehyde, and prescription retinoid mechanisms in normalising cell turnover. Guides appropriate retinoid selection and introduction protocols.

Lesson 4 • Ingredient Interactions and Formulation Safety

Identifies incompatible ingredient pairings and pH conflicts that reduce efficacy or cause irritation. Enables safe, effective multi-active regimen design.

Lesson 1 • Chemical Exfoliation Protocols

Details superficial and medium-depth peel procedures using AHAs, BHAs, and Jessner's solution. Connects peel selection to lesion type, Fitzpatrick skin type, and treatment goals.

Lesson 2 • Light and Energy-Based Acne Treatments

Covers blue light, red light, IPL, and LED therapy mechanisms for bacterial reduction and inflammation control. Guides device selection and treatment parameter setting.

Lesson 3 • Designing a Multi-Session Treatment Series

Guides construction of a phased treatment series with escalating intensity and home care integration. Ensures systematic progress toward clearance goals.

Lesson 4 • Manual Extraction Techniques

Teaches safe comedone and milia extraction methods using sterile instruments and correct pressure. Prevents trauma, scarring, and cross-contamination during procedures.

Lesson 1 • Regimen Compliance and Client Education

Develops strategies to improve client adherence through simplified routines and clear instructions. Reduces treatment failure caused by inconsistent home care.

Lesson 2 • Cleansing and Skin Preparation

Identifies appropriate cleanser types, pH ranges, and cleansing techniques for acne-prone skin. Establishes the foundation of an effective daily regimen.

Lesson 3 • Sun Protection for Acne Clients

Explains UV-induced post-inflammatory hyperpigmentation risk and sunscreen selection for acne skin. Integrates SPF into daily regimens without comedogenic risk.

Lesson 4 • Targeted Treatment Product Selection

Guides selection of serums, spot treatments, and leave-on actives for daily acne management. Matches product potency to acne severity and skin tolerance.

Lesson 1 • Post-Inflammatory Hyperpigmentation Management

Explains melanin overproduction following acne inflammation and evidence-based depigmenting strategies. Addresses Fitzpatrick-specific risks and ingredient selection.

Lesson 2 • Filler and Subcision for Depressed Scars

Introduces subcision and filler injection concepts for rolling and boxcar scars. Defines scope of practice boundaries and referral pathways.

Lesson 3 • Professional Resurfacing for Acne Scars

Reviews microneedling, medium-depth peels, and laser resurfacing for atrophic scar remodelling. Guides treatment selection based on scar depth and skin type.

Lesson 4 • Long-Term Scar Prevention Strategies

Establishes protocols to minimise new scar formation through early intervention and anti-inflammatory management. Integrates prevention into ongoing acne treatment plans.

Lesson 1 • Hormonal and Adult Female Acne

Addresses the unique pathophysiology and treatment approach for adult female acne driven by hormonal fluctuations. Integrates topical, nutritional, and referral strategies.

Lesson 2 • Pregnancy and Lactation Acne Protocols

Identifies safe and contraindicated ingredients for acne management during pregnancy and breastfeeding. Ensures client safety while maintaining treatment efficacy.

Lesson 3 • Treatment-Resistant and Severe Acne

Develops clinical reasoning for cases unresponsive to standard protocols, including nodular and cystic acne. Defines escalation pathways and medical collaboration.

Lesson 4 • Acne in Skin of Colour

Identifies heightened PIH and keloid risk in deeper Fitzpatrick skin types and adjusts protocols accordingly. Prevents treatment-induced complications in melanin-rich skin.
