About Me


Karla Cabrera was born in San Luis Rio Colorado, Sonora, México in 1988. When her mom asked her “the question,” the one everyone asks you when you start school, ‘What do you want to be when you grow up?’—Karla seriously replied, “I want to be an astronaut, a doctor, or a magician”; fast-forward almost three decades later, in 2018, Karla is the founder of Bella Medical Spa in Tempe, AZ, combining Western medicine with aesthetic magic. Karla is a board-certified nurse practitioner from Chamberlain College of Nursing, and she also pursued several certifications to become an advanced cosmetic injector. She is known in the medical aesthetic industry for producing natural, transformative results. Karla founded Bella Advanced Aesthetics Training and has personally educated a wide array of medical providers in the aesthetic community since 2019. Karla is detail oriented, driven, and perpetually trying to learn, expand, and enhance her medical aesthetic skills. In 2022, Karla opened her second location in Phoenix, Arizona, and she plans to expand her aesthetics services to include over 80 aesthetic treatments provided to her patients. Karla loves working in this industry and has a passion for helping her patients become the best refreshed version of themselves.

Why advanced injector trainings?

Aesthetic medical providers and nurse injectors are in high demand nowadays, and exciting new opportunities are opening every day in the field of aesthetic medicine, whether you desire to open your own medical aesthetic clinic or become an aesthetic injector for a corporation, advanced training is a commitment to yourself and to your future aesthetic patients to set you apart from other aesthetic providers. It is not safe and efficient to start injecting without proper advanced trainings, and if you are reading this, it is evident you felt basic training is just step number 1 out of 50 steps to become a well-rounded aesthetic injector. If you are looking to step up your aesthetic injector skill level, Bella Advanced Aesthetics Training is the perfect solution, as the focus is non-stop hands-on practice… the practice lacking in basic neuromodulators and filler trainings available nationally. Contact us today to learn more about setting up a customized training session with our advanced injector and National P.A.C.E. Trainer, Karla C., NP., and we can help you level up your aesthetic injector skills and guide you on your professional goals.

As a RN or future injectables clinic owner, why do I need a Medical Director?

All the accounts to order injectables and supplies require a medical license of an independent medical provider; therefore, you will not be able to order any products and supplies or get liability insurance coverage without a certified aesthetics medical director. Karla Cabrera, FNP-C, provides Medical Director services to medical spa clinics for RF devices, laser hair reduction, neuromodulators, fillers, IV therapy, and several other aesthetic treatments. We ensure medical supervision of the patient care protocols and guidelines in compliance with applicable AZ regulations. We provide turn-key assistance to medical spas providing all required compliance protocols, treatment consent forms, patient documents, treatment protocols, complication management protocols, and medical supplier accounts you need to run your medical aesthetics business. NP Karla is licensed to practice medicine in Arizona and have records in good standing with the state nursing board. NP Karla is qualified by National Laser Institute and Arizona Board of Nursing to oversee the treatments she supervises. NP Karla has been trained and is a certified medical aesthetics medical director.
