Which practice is illegal for a licensed beauty technician?

Using unapproved products is considered illegal for a licensed beauty technician because it directly relates to the health and safety of clients. Beauty technicians are required to use products that are sanctioned by regulatory bodies to ensure they meet safety standards and do not pose any risks to clients. Using products that have not been approved could lead to harmful reactions, infections, or damage to the skin and eyelashes, making it crucial for technicians to adhere to guidelines regarding product use.

In contrast, aesthetic massages are often part of a licensed technician's training, and providing consultations is typically within their scope of practice, as it helps clients make informed decisions about treatments. Utilizing personal devices can also be a part of the technician's workflow as long as proper sanitation and safety protocols are followed. The focus on using only approved products serves to protect both the technician and the client from potential hazards.
