In recent years, microneedling (also known as collagen induction therapy) has become very popular in the realm of skin rejuvenation. The reasons for this are simple: It produces visible results, there are few possible complications, and it is extremely simple—a patient can undergo a basic microneedling procedure in a matter of minutes.
Microneedling is also popular with medical spa owners, because it is often performed by an aesthetician without supervision and without a workup or examination, so the profit margins for these treatments are quite high. However, in most cases, aestheticians should not be performing these procedures. Even though there is some gray area regarding the finer points of the law when it comes to microneedling, it is in a business’s best interest to view it strictly as a medical treatment.

This can help to reduce the appearance of fine lines, wrinkles and stretch marks without the pain of epidermal abrasion. At lower depths, microneedling can also be used to treat rosacea and scarring.¹
