As the new kid on the block, medical spas are breaking the mold of the traditional medical practice model. The merging of medicine and day spa services has created a new industry with multiple governing authorities to regulate it and the varying roles within it.

Most medical spas provide some combination of medical and aesthetic procedures—lasers, Botox, fillers, Kybella, microneedling, microdermabrasion, dermaplaning, chemical peels, dermabrasion and CoolSculpting. Often, this menu of services blurs the line between medical and spa treatments. While these procedures are considered medical in most states, exemptions exist in others. For example, the cosmetology boards of certain states allow aestheticians and cosmetologists to perform microdermabrasion and dermaplaning, as long as the procedure does not penetrate the dermal layer of the skin. On the other hand, more restrictive state regulating boards limit aesthetic and cosmetology practices to the topmost layer of the skin. This leads to the common question—who can do what in a medical spa?

The authority to administer medical aesthetic treatments follows a basic hierarchy:

  1. Physician;
  2. Nurse practitioner (NP) and physician assistant (PA);
  3. Registered nurse (RN);
  4. Licensed practical nurse (LPN)/licensed vocational nurse (LVN); and
  5. Aesthetician, cosmetologist and unlicensed personnel.


Physicians have the broadest authority and often fill the role of owner or medical director in medical spas. The delegation of medical treatments to the rest of the staff falls under the supervision of these physicians, and sometimes NPs and PAs.

NPs and PAs

Certain states grant independent practice authority to NPs, and in those states, physician delegation or supervision is not required. Independent practice NPs can provide medical procedures falling under their scope of practice. Where NPs due not have autonomy, state laws generally indicate the level of physician supervision required for both NPs and PAs. In most cases, NPs practice in collaboration with a physician. Depending on the state's laws, collaboration commonly follows written protocols (e.g., a list of delegated medical tasks, restrictions or limitations, prescriptive authority and level of supervision). Similarly, PAs usually practice pursuant to a supervision or delegation agreement, addressing their scope of practice and any applicable restrictions.


The scope of practice of an RN is more limited and subject to stricter delegation and supervision than that of an NP or PA. Unless state law dictates otherwise, a qualified physician or independent practice NP may delegate medical tasks to RNs, as long as the procedure is within their scope of practice and competency has been verified. If required, written protocols are delineated and appropriate supervision provided. If state laws do not define the level of supervision, the delegating practitioner must use their professional judgement to identify and engage in it appropriately.


The scope of practice of LPNs/LVNs is more limited and subject to stricter delegation and supervision than an NP, PA or RN. State laws generally dictate the medical tasks that a qualified physician or independent practice NP can delegate to LPNs/LVNs, whether written protocols are required, and the appropriate level of supervision. Similar to RNs, if state laws do not define the level of supervision, the delegating practitioner must use professional judgement to identify and engage in it appropriately.

Aestheticians and Cosmetologists

There is much confusion in the medical spa world about who is considered licensed personnel. While aestheticians and cosmetologists are licensed by cosmetology boards, they are considered unlicensed personnel by medical standards. They generally are permitted to perform spa procedures—e.g., facials and certain types of massages—that fall under their cosmetology licensure, but prohibited from doing anything requiring medical training.

Unlicensed Personnel

In addition to estheticians and cosmetologists, medical assistants (MAs) are considered unlicensed personnel for medical treatments and can perform treatments in medical spas only as state law allows. With limited to no medical training, these staff members generally are not permitted to perform medical or invasive procedures. Even if state law allows delegation, it often requires that the delegating practitioner provide onsite direct supervision during procedures. Delegation of medical treatments to unlicensed personnel must be approached with extreme caution.

From state to state, laws related to medical spa treatments vary from the very detailed to the very sparse, leaving room for legal interpretation.
