I. Background

“Microneedling products” is a generic term that encompasses instruments with common technological features that include an array of needles, “micro-protrusion” tips, or pins, which can be blunt or sharp, and of varying lengths. This document discusses when a microneedling product is a device as defined under section 201(h) of the FD&C Act (21 U.S.C. 321(h)), and is, therefore, subject to the device requirements under the FD&C Act and its implementing regulations.[1] This guidance also provides clarity on the regulatory pathway to market for microneedling devices for aesthetic use, resulting in more transparency and predictability to firms and stakeholders, which may translate into more efficient device development and patient access to such devices. The scope of this guidance document does not include microneedling combination products, acupuncture needles, hypodermic needles or other needles for injection, tattoo machine needles, needle probes that emit any type of energy (e.g., radio-frequency needles) or deliver any type of energy to a patient (e.g., LASER, ultrasound), or dermabrasion devices. FDA considered comments received on the draft guidance that appeared in the Federal Register of September 15, 2017 (82 FR 43383). FDA revised the guidance as appropriate in response to the comments. Further, the guidance was revised to account for a De Novo request that was granted since issuance of the draft, which classified microneedling devices for aesthetic use into class II subject to premarket notification requirements under section 510(k) of the FD&C Act ((21 U.S.C. 360(k)) and special controls. The classification is codified at 21 CFR 878.4430.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Regulatory Considerations for Microneedling Products.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

1.  On September 23, 2020, FDA published a proposed rule to amend its intended use regulations for medical products (21 CFR 201.128 and 801.4) to better reflect the Agency's current practices in evaluating whether a product is intended for use as a drug or device. As described in the proposed rule, FDA's longstanding position is that, in evaluating a product's intended use, any relevant source of evidence may be considered, including a variety of direct and circumstantial evidence. 85 FR 59718, 59721 (Sept. 23, 2020).
