Cosmetic Dermatology Course
Master the full spectrum of cosmetic dermatology — from skin biology and chemical peels to injectables, lasers, and practice management. 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.
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.

Chapter 4HideHide detailsSee detailsChemical Peels: Theory and Practice
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.
