This course delivers the clinical knowledge and hands-on protocols you need to treat patients safely, achieve consistent aesthetic results, and build a thriving cosmetic practice.

Dedika for businesses

What you'll learn:

This course covers skin anatomy, Fitzpatrick typing, and the ageing mechanisms that underpin every cosmetic decision you will make. You will learn to assess patients systematically, design individualised treatment plans, and formulate evidence-based home-care regimens. Chemical peel theory, laser physics, and energy-based device protocols are covered in clinical depth. You will develop precise injection techniques for botulinum toxin and dermal fillers, including vascular complication management. The curriculum also addresses skin of colour, ethics, informed consent, and the business strategies needed to grow a sustainable aesthetic practice.

  • Lesson 4 • Retinoids: Mechanisms and Clinical Use

    Explains retinoid receptor pharmacology and clinical applications for ageing and acne. Establishes retinoids as a cornerstone of cosmetic topical therapy.

  • Lesson 5 • Exfoliants: AHAs, BHAs, and Enzymes

    Differentiates chemical exfoliant classes by mechanism, depth, and skin type suitability. Prepares students to prescribe exfoliants that optimise skin texture and product penetration.

Chapter 4See details

Chemical Peels: Theory and Practice

  • Lesson 1 • Peel Classification and Mechanisms

    Categorises peels by depth—superficial, medium, and deep—and explains their chemical mechanisms. Establishes the framework for matching peel depth to clinical indication.

  • Lesson 2 • Complications and Their Management

    Identifies and treats peel complications including prolonged erythema, scarring, and hyperpigmentation. Builds clinical confidence through systematic complication recognition and response.

  • Lesson 3 • Superficial and Medium Peel Application

    Teaches step-by-step application technique for glycolic, salicylic, Jessner's, and TCA peels. Develops hands-on precision for controlled, reproducible peel outcomes.

  • Lesson 4 • Pre-Peel Skin Preparation

    Details priming protocols using retinoids, depigmenting agents, and sun avoidance before peel application. Proper preparation maximises results and reduces adverse events.

  • Lesson 5 • Post-Peel Care and Recovery

    Outlines wound care, moisturisation, and sun protection protocols during the peeling phase. Ensures patient compliance and minimises downtime complications.
