Karen is an amazing professional. Over the past several months, she has helped me through a variety of procedures and has always been incredibly supportive. She takes the time to explain every detail, including the benefits, potential risks, … More and expected outcomes, so I always feel informed and comfortable with my decisions.
What truly sets her apart is the care she provides after each procedure. She consistently follows up on my recovery and checks on my results, showing genuine concern for her patients’ well-being. Karen is honest, knowledgeable, and trustworthy, and her pricing is more than fair for the exceptional level of care she provides. I highly recommend her to anyone looking for a skilled and compassionate professional.

I had an amazing experience with Karen Tossi at KT Brazilian Aesthetic! From my very first appointment, I was welcomed by a professional, caring, and friendly team that made me feel comfortable and well taken care of.
I used Zo Skin Health … More products as part of my treatment plan, and I am extremely happy with the results. My skin looks healthier, brighter, smoother, and more radiant than ever. Karen is highly knowledgeable, took the time to explain every step of the process, and created a personalized approach that delivered outstanding results.
The entire staff at the clinic provides exceptional customer service, and every visit has been a wonderful experience. I highly recommend KT Brazilian Aesthetic to anyone looking for top-quality treatments, excellent care, and visible results!

Pleasure to meet you! I’m Karen Tosi, Master Injector and Specialist Nurse.

My journey has always been about precision, safety, and real transformation.

Nursing taught me the essence of care. Aesthetic injectables gave me the opportunity to enhance beauty with techniques that respect the uniqueness of every face.

In the U.S., I refined my expertise in advanced facial harmonization, wrinkle relaxers, and dermal/lips fillers, combining science and artistry to achieve natural, refined results.

At KT Aesthetics, our mission is clear: to boost your confidence with safe, personalized injectables, performed with the highest level of precision.

Welcome to a new standard of beauty—where every detail makes a difference.
