Advanced Facial Aesthetic Techniques
Advanced items test whether you can combine techniques safely: choosing depth and energy, priming the skin, spacing sessions, and knowing when to stop or refer.
Technique essentials
- Microneedling: controlled micro-injury stimulates growth factors and collagen. Cosmetic depths are typically 0.5–1.5 mm, thinner on the forehead and neck; 4–6 week intervals; avoid active acne, active infection, isotretinoin within six months, keloid tendency, anticoagulants and pregnancy.
- Dermaplaning: mechanical removal of vellus hair and stratum corneum; never over inflamed acne or couperose skin.
- Peel layering: combining agents (for example a resorcinol-based solution with low-percentage TCA) deepens penetration; it also multiplies risk, so it demands priming, precise timing and a neutralisation plan.
- Radiofrequency: bulk dermal heating to about 40–45 °C; bipolar is more controlled; contraindicated with metal implants in the field and pacemakers.
- HIFU: focused ultrasound at fixed depths; operator training and correct cartridge selection matter more than energy.
Priming and skin of colour
Two to four weeks of a barrier-supporting routine with a tyrosinase inhibitor reduces post-inflammatory hyperpigmentation risk. In Fitzpatrick IV–VI, prefer mandelic, lactic or low-percentage salicylic acid, avoid aggressive abrasion, and be cautious with heat-based devices.
Spacing and combination
Do not stack aggressive modalities in one session. Superficial peels every 2–4 weeks, microneedling every 4–6 weeks, RF as a course, HIFU as a single session with long review intervals. Record depth, energy, passes and passes per zone.
Worked example
A Fitzpatrick V client requests a medium-depth peel before a wedding in ten days. Reasoning: high PIH risk, compounded by a short deadline that leaves no room to manage a reaction. Correct response: decline the medium peel, offer a priming routine plus a series of mandelic acid peels starting well before the event, and note the discussion.
Traps that cost marks
- "More passes means a better result".
- Treating over active acne, cold sores or broken skin.
- Skipping priming in darker skin.
- Scheduling a resurfacing treatment days before a major event.
