A medical spa, often referred to as a "med spa" or "medi-spa," is a hybrid between a traditional day spa and a medical clinic. It offers a range of cosmetic treatments and procedures that are more advanced than those typically found in a regular spa but are less invasive than those performed in a medical clinic or hospital setting. Medical spas are designed to provide a relaxing and rejuvenating experience while offering cosmetic and aesthetic services under the supervision of licensed healthcare professionals - read more here. 

In medical spas, treatments are administered by licensed and trained professionals who have expertise in the field of cosmetic and aesthetic procedures. The specific individuals who provide these treatments can vary based on the nature of the procedure and local regulations.

Common Professionals Found in Medical Spas:

• Medical Doctors (MD) and Doctors of Osteopathic Medicine (DO)
• Nurse Practitioners (NP) and Physician Assistants (PA)
• Registered Nurses (RN)
• Licensed Aestheticians

Before undergoing any cosmetic procedure at a medical spa, it's recommended to research the credentials of the professionals involved, inquire about their training and experience, and ensure that the facility follows appropriate safety standards. Always schedule a consultation to discuss your goals, receive personalized advice, and ask any questions you may have about the proposed treatments.
