In this episode:

Why the Fitzpatrick scale was created in 1975 to predict sunburn and skin cancer risk, not laser response

Eumelanin versus pheomelanin, and what each means for photoprotection

Why you never hand a patient the skin-typing form, and the questions they almost always answer wrong

How the aesthetic industry adopted Fitzpatrick for devices, and why fluence charts still lean on it

Why a tan doesn't change a patient's type, and what fluence should depend on instead

The Roberts Skin Type Classification System: phototype, hyperpigmentation, Glogau photoaging and scarring, combined into one code

The palmar assessment and the Lancer scale, and the gaps they fill

Building a full risk profile before you choose a treatment

As Tracey puts it: "Energy-based medicine requires risk-based stratification, not just some visual assumption." And on the intake form: "Unless they live in a cave, they are going out in the sun."

In this episode:

Where to start if you're buying your first device, and the treatments that are reliably in demand

Why after-sale service is the single most important thing to check, and how to check it before you buy

What real supplier support looks like beyond the one-day training: marketing, events, and turnaround when something breaks

Asking reps for consumables, practice tips and event budget, and why they usually say yes

Hype versus science: what a heavily marketed brand genuinely buys you, and what it doesn't

Bringing your team into the decision, and the head spa she bought without asking them

Getting past the fear of the price tag by treating it as a monthly payment

Rapid fire: proven or new, one platform or several, and what matters more than the technology

As Alicia puts it, on chasing the brand everyone knows: "At the end of the day, the science is the science. You can get exactly the same results with a different machine if you know what you're doing and you're trained properly." And on where to get a straight answer: "If you wanna know the real information about the device, ask the trainers. The sales reps sometimes don't really know exactly what the device can do or not do."

As Tracey Hotta puts it, on informed consent: "If it's documented in the literature and something happens and you haven't told them, you're accountable." And on the Instagram version of the job: "They go, oh my God, there's so much to learn. It's like, yeah, it's medicine. There's a lot to learn."

Why over-cleansing and over-exfoliating make acne worse, and what barrier-first treatment looks like instead
Reading the pattern: cyclical jawline breakouts versus uniform, itchy presentations, and why one patient often has several types at once
A severe cystic acne case: two weeks of stopping everything, then a simple routine, then mapped microneedling
Where Alex stands on microneedling over active acne, including her extraction and antimicrobial protocol
