CHOOSE AN EXPERT INJECTOR! Not all injectors are created equal! An expert injector has special training/certification in all dermal fillers, their uses and the most effective injection methods. As an Expert Injector, Sharon has additional specialized training and is specially trained and certified. She believes in using only Medical Grade product, so you are always getting the BEST! Some clinics don't use medical grade product which means it's watered down and you are therefore paying for more product and less results.
