Lesson 1Microdermabrasion and superficial resurfacing: mechanical epidermal removal effects, adjunctive uses and limitationsThis section covers microdermabrasion and other superficial resurfacing methods for stretch marks. You will learn how controlled epidermal removal affects texture, how to combine with topicals, and where these techniques are limited or contraindicated.

We cover thermal remodelling, depth of heating, parameter selection, safety in darker skin common in Namibia, and realistic timelines for visible improvement.

We cover PIH, erythema, oedema, infection, and scarring, with prevention strategies, early detection, and stepwise interventions.

We review wavelength families, pulse parameters, spot sizes, and strategies to minimise hyperpigmentation and textural complications.

You will review proposed mechanisms, injection parameters, evidence quality, and contraindications, plus how to counsel patients on realistic expectations.

We cover glycolic, lactic, and TCA peels, their epidermal and dermal actions, phototype-based selection, and key risks, contraindications, and aftercare.

You will learn pass numbers, spacing, and post-care to optimise safety and results.

We discuss rationale for sequencing, synergy versus additive risk, washout periods, and how to adapt plans to phototype, lifestyle, and prior treatment history.

You will review wavelengths, protocols, clinical outcomes, and key safety and efficacy limitations.

You will compare mechanisms, evidence levels, tolerability, and integration with procedures.
