Advanced Facial and Body Skin Treatments
What you must understand
This domain covers chemical peels, microdermabrasion, dermaplaning, extraction, massage, masks, and body treatments such as wraps and keratolytic regimens. Know peel depth categories - superficial (stratum corneum to papillary dermis), medium, and deep - and the acids used, their concentrations, pH, and neutralisation requirements. Understand skin preconditioning, priming with retinoids or depigmenting agents, and post-treatment barrier repair. Body treatments require attention to larger surface areas, occlusion, and systemic absorption.
Traps in questions
A classic trap is confusing acid concentration with strength: pH and free-acid availability matter as much as percentage. Another is assuming all peels need neutralising - some self-neutralise, others do not. Questions may test layering: combining modalities in one session increases risk and must be justified. Do not overlook post-peel care; inadequate photoprotection and barrier support drive complications. Body wraps that occlude the skin can increase absorption of active ingredients, so check for allergies and systemic conditions.
Rule of thumb
Use the "one variable at a time" rule: change either depth, area, or active agent per session, not all three, so any reaction can be attributed and managed.
Worked example
A client new to peels receives a superficial lactic acid peel at low free-acid strength on a small test area first. If tolerance is good, the next session may increase contact time - but not simultaneously switch to a deeper acid and a larger area.
