Tattoo removal is generally considered an invasive procedure, especially when it involves techniques like excision or laser treatment without the proper oversight of laser-specific training or licensing. While some forms of tattoo removal, such as those involving specific laser techniques, can be non-invasive, the overall categorization leans more towards being a procedure that borders on invasive due to the permanence of the ink and the necessary intervention to remove it.

On the other hand, neurotoxin injection, dermal filler injection, and microdermabrasion are established as non-invasive procedures widely recognized in the cosmetic industry. Neurotoxin injections, like Botox, temporarily paralyze muscles to reduce wrinkles, while dermal fillers restore volume and fullness to the skin. Microdermabrasion is a technique used to exfoliate the skin's surface, promoting rejuvenation without the need for surgery. Thus, the distinction lies in the nature of the procedures and their accepted classifications within cosmetic practices.
