Granulomatous Reactions From Microneedling: A Systematic Review of the Literature
Abstract
BACKGROUND: Microneedling is a common minimally invasive procedure for skin rejuvenation. Granulomatous reactions after microneedling have been rarely reported. OBJECTIVE: To systematically review the literature for granulomatous reactions from microneedling. MATERIALS AND METHODS: A systematic review of the Medline, Scopus, Google Scholar, and Cochrane databases was performed for articles describing granulomatous reactions to microneedling. RESULTS: Thirteen studies were selected for inclusion after full-text review, which described 15 patients (26–74 years old) with non-necrotizing granulomatous inflammation postmicroneedling. Motorized microneedling pen use and topical Vitamin C application were implicated in a majority of cases. Although delayed-type hypersensitivity was commonly proposed as the underlying etiology, patch testing or further workup was rarely performed. Improvement or clearance occurred inconsistently with myriad treatment options, including topical steroids, oral antibiotics, and systemic anti-inflammatory medications. CONCLUSION: Granulomatous reactions to microneedling and microneedling-mediated transepidermal drug delivery can rarely occur and may be treatment-resistant.

“Although vitamin C (ascorbic acid or tetrahexyldecyl ascorbate) was implicated in 60% of these cases, there is currently insufficient evidence to suggest direct causation.28”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
