Chemical Peels
This course completely changed how I approach peels. The depth of ingredient science was exactly what I needed to feel confident with stronger formulations.
Maria Santos
Licensed Esthetician, Miami
Chemical Peels
Clear, practical, and well-structured. I was able to apply what I learned on my very next client. The protocol breakdowns are invaluable.
Lisa Chen
Spa Owner, Fort Lauderdale
Chemical Peels
Finally, a peels course that goes beyond the basics. The contraindication section alone saved me from making a costly mistake with a reactive client.
Jennifer Kowalski
Esthetician, Boca Raton
ACTIVE LAB
Active Lab gave me a framework for layering actives that actually makes sense. My clients are seeing results faster and I can explain exactly why.
Daniela Reyes
Clinical Esthetician, Tampa
ACTIVE LAB
I loved how each ingredient was broken down with real use cases. This isn't theory for the sake of theory — it's immediately useful in the treatment room.
Sarah Mitchell
Esthetician, Orlando
ACTIVE LAB
Compact but incredibly dense with information. I keep coming back to the reference guides. Worth every penny.
Ana Petrova
Skin Therapist, Naples
ACNE RESET: Skin Script
Acne Reset changed how I consult with acne clients. The Skin Script protocol is straightforward and my clients are finally sticking with their routines.
Rachel Kim
Esthetician, Coral Gables
ACNE RESET: Skin Script
The before-and-after case studies were incredibly motivating. I've already adapted the reset protocol for three clients with great results.
Emily Torres
Licensed Esthetician, West Palm Beach
ACNE RESET: Skin Script
Clear step-by-step guidance on product selection and timing. This removed so much guesswork from my acne treatments.
Natalie Cruz
Spa Therapist, Hollywood FL
Chemical Peels Masterclass
Hands-on practice with real models made all the difference. I walked out feeling 100% ready to offer advanced peels at my studio.
Amanda Brown
Esthetician, Aventura
Chemical Peels Masterclass
The instructor corrected my technique in real time — something no online course can do. Small group size meant plenty of personal attention.
Sophia Delgado
Skin Care Specialist, Doral
Chemical Peels Masterclass
Excellent workshop. The printed protocols and checklists are now taped to my treatment room wall. Highly recommend for anyone serious about peels.
Victoria Lamb
Licensed Esthetician, Plantation
Active Ingredients Lab
Getting to mix and test formulations ourselves was the highlight. I finally understand pH levels and penetration in a way textbooks never taught me.
Megan Hart
Clinical Esthetician, Pembroke Pines
Active Ingredients Lab
Small group, expert instructor, real products. This is the kind of education that levels up your practice overnight.
Isabella Fontaine
Esthetician, Coconut Grove
Active Ingredients Lab
I came for the ingredient science and left with an entirely new treatment menu. The ROI on this workshop was immediate.
Christina Vega
Spa Manager, Key Biscayne
Acne Skin Intensive
Practicing extractions and peel application on models with actual acne was invaluable. You can't get this experience anywhere else.
Patricia Nguyen
Esthetician, Sunrise
Acne Skin Intensive
The error analysis portion was humbling but so helpful. I didn't realize how many small technique issues I had until the instructor pointed them out.
Lauren James
Skin Therapist, Weston
Acne Skin Intensive
Walked in nervous about treating severe acne. Walked out with a clear protocol and the confidence to take on those clients. Life-changing workshop.
