Chemical Peels

Chemical Peels Lesson

Chemical peels are a method of controlled exfoliation used in aesthetic cosmetology to improve skin texture, regulate epidermal processes, and support dermatological therapies. In this lesson, you'll explore the mechanisms of exfoliating agents, acid classifications, treatment indications and contraindications, and how to safely combine peels with other procedures.

Level 1

What you’ll learn – theory

• Definition of chemical peels – controlled exfoliation using chemical agents to remove dead skin cells.
• Classification of peels – superficial, medium-depth, and deep peels based on penetration level.
• Types of peels – simple, combined, gel-based, and alcohol-based; their formulas, usage, and differences.
• Properties of AHA, BHA, AKA, and PHA acids – their mechanisms, indications, and combinations.
• Exfoliation mechanisms – how peels remove cells and stimulate skin renewal.
• Peel selection – choosing the right acid for acne, hyperpigmentation, wrinkles, or laxity.
• Treatment effects – skin brightening, texture improvement, and cellular stimulation.
• Cell and tissue structure – to understand skin responses and regeneration.
• Facial bone structure – important for working near anatomical landmarks.
• Facial vascular system – to avoid irritation in sensitive areas.
• Facial nerve structure – essential for comfort and safety during application.
• Facial muscles – their influence on skin tension and elasticity.
• Skin anatomy – layers of the epidermis and their interaction with acids.
• Skin conditions – that are either contraindications or indications for chemical peels.
• Application tools – brushes, gauze, spatulas and how to use them safely.
• Peel layering and timing – how to combine acids and structure multi-session therapy.
• Contraindications – including inflammation, herpes, and impaired skin barrier.
• Skin typing and diagnostics – to tailor acid strength and approach.
• Client qualification – including interview, skin assessment, and treatment goals.
• Treatment setup – space organization, disinfection, and aseptic protocols.
• Product overview – active ingredients, neutralizers, and post-peel care.
• Precautions – including eye protection, avoiding wounds, and timing control.
• Step-by-step chemical peel procedure – from skin prep to post-treatment recovery.
• Post-treatment recommendations – sun protection, home care, and avoiding irritants.
• Combining chemical peels – with mesotherapy, dermaplaning, or LED therapy.

What you’ll learn – practice

• Workstation setup – aligned with hygiene, safety, and client comfort standards.
• Materials needed – acids, neutralizers, applicators, sanitizers.
