Part 2: Introducing DermaSensor™—The Smartest Skin Check You’ve Never Heard Of
By Stefani Heisler, PA-C | Owner & Aesthetic Specialist, Simply You By Stef

Reader Question
Joel, 54, an avid golfer from Winter Park, asks:
“I’ve had the same spot on my arm for years, and I don’t want to overreact—but I also don’t want to miss something serious. I hate the idea of waiting six months for a derm appointment. What can I do?”
Introduction
Here’s a not-so-fun fact: The U.S. is facing a shortage of dermatologists—and patients often wait weeks or even months for a simple skin check.
But what if you could get a real-time, non-invasive, FDA-cleared skin cancer assessment in the comfort of your local medspa?
Enter DermaSensor™, one of the most exciting medical technologies in skin cancer detection—and now available at Simply You by Stef.
We are proud to be one of the first aesthetic practices in Central Florida offering this life-saving device. And no, you don’t need a referral or waitlist to access it.
What Is DermaSensor™?
DermaSensor™ is a handheld, AI-powered device that helps healthcare providers evaluate suspicious skin lesions in real time—without cutting, scraping, or waiting.
It uses Elastic Scattering Spectroscopy (ESS)—a safe, light-based technology that reads beneath the surface of the skin and provides instant risk assessments for all three common skin cancers:
- Basal Cell Carcinoma (BCC)
- Squamous Cell Carcinoma (SCC)
- Melanoma
Highlights:
- FDA-cleared in 2023
- Non-invasive (just light—not heat, not lasers)
- Assessment takes less than 60 seconds per lesion
- Uses AI to analyze molecular structures in skin tissue
- Helps accelerate referrals to dermatologists when needed
Expert Insight
“This is one of the most important diagnostic advancements I’ve seen in 25 years of practice. It doesn’t replace dermatologists—it empowers providers like me to identify concerning lesions early, and make informed referrals before the risk escalates.”
— Stefani Heisler, PA-C

Real Client Perspective
“I’d been ignoring a dark spot on my shoulder for years. Stef scanned it in the office—it came back as suspicious. She helped me book a derm referral that week. Turns out it was early-stage melanoma. I had it removed, and now I’m fine—but I’ll never wait again.”
— Michael, 61
Why It Matters at SYBS
- We use DermaSensor™ to evaluate suspicious spots during skin assessments
- If the lesion shows high risk, we refer to our trusted dermatology partners
- You’ll receive a report and guidance on your next step—on the same day
- No guesswork. No waitlists. No unnecessary panic.
This is not a replacement for dermatology, but it’s an essential first line of defense—especially for high-risk clients and those who want peace of mind.Who Should Consider It?
- Adults over 40
- Clients with a history of sun damage or tanning
- Clients with more than 20 moles or atypical-looking lesions
- Anyone with changing, itching, bleeding, or new spots
- Clients who haven’t had a skin check in over a year
We recommend a yearly scan, especially for Floridians exposed to high levels of UV radiation year-round.
Final Thoughts
DermaSensor™ isn’t about fear—it’s about empowerment. It gives us the ability to spot potential problems before they become serious, and connect you with the care you need faster.
If you’ve ever had a “weird spot” you weren’t sure about… let’s check it.
