Who Not to Treat: The Screening Red Flags That Protect Clients and Licenses

The most professional sentence in aesthetics is \”this treatment is not right for you today.\” Screening red flags protect clients from harm and clinics from the complaints, refunds and regulatory attention that follow bad selections.

Universal Red Flags (All Energy Devices)

• Pregnancy and breastfeeding — elective energy work deferred across the board
• Active infection, open wounds, or inflamed eczema in the treatment zone
• Photosensitizing medications — recent isotretinoin history is the classic gate for ablative work
• Unrealistic expectation that survives two honest conversations — the consultation is a two-way screen

Device-Specific Gates

1. Laser hair removal: recent waxing (follicle removed), tattooed zones in path, tanned skin without wavelength adjustment
2. HIFU: metal implants in zone, active acne flare, thyroid-zone proximity without protocol discipline
3. RF microneedling: active herpes simplex per medical protocol, keloid history warrants patch-first caution
4. Pigment lasers: melasma misidentified as lentigines — the misdiagnosis that creates the worst outcomes

The System

A written screening form signed every visit, not just the first — medications and conditions change mid-course. Document the declined treatment and the reason: a documented \”no\” is the best defense a clinic owns. Operators running ablative platforms carry the longest red-flag list; the operator checklist pairs with this screen at every session.
