The United States Food and Drug Administration (FDA) conducted an inspection of your firm’s medical device operations at 3600 Chamberlain Lane, Suite 336, Louisville, KY, from June 15 – June 29, 2021. During the inspection, an FDA investigator from the United States Food and Drug Administration (FDA) determined that your firm is a manufacturer of Collagen P.I.N., a microneedling product. Under section 201(h) of the Federal Food, Drug, and Cosmetic Act (the Act), 21 U.S.C. § 321(h), this product is a device because it is intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, or intended to affect the structure or any function of the body.
The agency has reviewed the product labeling for the Collagen P.I.N, including brochures, pamphlets, and your firm’s website at Inductiontherapies.com. This review revealed statements that establish that the Collagen P.I.N. is intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, or intended to affect the structure or any function of the body, including:
• Per your firm’s brochure. “Collagen P.I.N. is a method of (b)(4).”
• Per your firm’s labeling, “Collagen P.I.N. is a Class 1 FDA registered medical device for Percutaneous Collagen Induction Therapy. This device should only be used by or under the supervision of a physician. Supervising Physician ultimately decides all protocols for treatments.”

It is also considered a valuable alternative to more invasive procedures such a laser skin resurfacing and deep chemical peeling.”
• Per your firm’s website, “SKIN CONCERNS - Collagen P.I.N, addresses most major skin concerns Including fine lines and wrinkles, aging, sun damaged skin, peri-oral rhytides. melasma, hyperpigmentation issues, acne scarring and rough texture just to mention a few. With only 3 to 6 treatments you can achieve long-term sustainable results when supported by the Induction Therapies product line.”
Our inspection, review of materials collected during the inspection, and review of your firm’s website, revealed that the Collagen P.I.N. is offered for sale and distributed in the United States without marketing approval, clearance, or authorization from FDA. Accordingly, the Collagen P.I.N. is adulterated under section 501(f)(1)(B) of the Act, 21 U.S.C. § 351(f)(1)(B), because your firm does not have an approved application for premarket approval (PMA) in effect pursuant to section 515(a) of the Act, 21 U.S.C. § 360e(a), or an approved application for an investigational device exemption under section 520(g) of the Act, 21 U.S.C. § 360j(g). The Collagen P.I.N. is also misbranded under section 502(o) of the Act, 21 U.S.C. § 352(o), because your firm did not notify the Agency of its intent to introduce the device into commercial distribution, as required by section 510(k) of the Act, 21 U.S.C. § 360(k). The introduction or delivery for introduction of this product into interstate commerce is prohibited under section 301(a) of the Act, 21 U.S.C. § 331(a).

Additionally, should FDA determine that you have Quality System regulation violations that are reasonably related to premarket approval applications for Class III devices, such devices will not be approved until the violations have been corrected. Also, should FDA determine that your devices do not meet the requirements of the Act, requests for Certificates to Foreign Governments (CFG) may not be granted.
