Here are my two cents, for what it’s worth: I highly recommend, as an “inexperienced aesthetician,” that you find a skin care job at a good salon or spa. The first few years after skin care school are when your education truly begins. Right after school and without practical experience, you are not an ideal candidate to open a business. If I were a client, I would want an aesthetician with at least a few years on the job before I would be willing to give her a chance—after all, this is a pricy service and no one is looking for a novice. You must work on many faces before you really know your stuff.
Find a quality salon and work there for a few years in the security of being paid to learn vs. starting out on your own with all the responsibilities of running your own business and learning about skin care. I have had my own salon(s) for over 20 years—working for nearly ten years for other people—and I so don’t recommend starting out the way you are thinking about. Your ego may be disagreeing with me right now, but you asked so I am giving you my opinion.
Best wishes on your quest for a successful skin care career.
