The Clinic

Be Vain Beauty is a subsidiary of Stone Med for our non-insurance based services. A multifaceted business that will go above & beyond to ensure your satisfaction.


All services are preformed in-office in a discreet medical setting; this ensures optimal comfort during a possibly sensitive procedure. We will go above and beyond to ensure that you're satisfied with your treatment & are treated well throughout your experience with us. 


We offer many different treatments to choose from including Aerolase cosmetic laser, mincroneedling (opt. PRP), IV hydration (Myers cocktail, etc.), cosmetic filler, and even bio-identical hormone pelleting. We're also a part of primary care & pain practice we have many different outlets at our disposal. 

Our Philosophy

Modern day society has us focusing on everything but ourselves and our own wellbeing. It's the philosophy of Be Vain that it is ok to love/pamper yourself now & then. Growing up, Peter struggled greatly with self image and this helped launch his career in beauty, health, & wellness. His ultimate goal is helping people love themselves & feel confident in their own skin.
