Efficacy Evaluation of the Pixie® Skin Tag Cryogenic Device on Skin Tags in a Prospective, Single-Blinded, Randomized, Comparative Clinical Trial

Abstract

Introduction Cryotherapy is an efficient method to treat various cutaneous lesions. In the current clinical evaluation, the efficacy of the Pixie ® Skin Tag cryogenic pen as a home treatment for benign skin tags was evaluated against a marketed comparator device. In addition, the safety, tolerability, and expected visual effects of the treatment were assessed. Methods Fifty-six healthy volunteers presenting with skin tags were included and randomized in a prospective, single-blinded, parallel, single-center, comparative trial and subjected to treatment with either Pixie ® Skin Tag or a comparator device, Wortie ® skin tag remover. Selected skin tags located on the neck, breast, and under the armpits were topically treated according to device prescriptions for maximally three times with a 15-day interval between treatments. Results Of the skin tags treated with Pixie ® Skin Tag, 64.3% completely disappeared during the study, of which half of the skin tags were cleared after one treatment, compared with 7.1% of the study population treated with Wortie ® skin tag remover ( p < 0.001). Both medical devices were safe to use, painless, and very well tolerated by 64.3% in the Pixie ® Skin Tag and 96.4% in the Wortie ® skin tag remover group. In addition, 72% of the subjects using Pixie ® Skin Tag were satisfied with the results, and two-thirds of this study group would buy and use the device for the treatment of other skin tags. For the comparator device, only 11.0% were satisfied and 7.0% would buy the device. Conclusion Treatment of skin tags with Pixie ® Skin Tag showed superior clinical performance when compared to Wortie ® skin tag remover. Both treatments were safe and well tolerated, with the majority of skin response serving as a predictor for clinical performance in the Pixie ® Skin Tag treated group.

Prevalence of skin diseases among hostellers attending the tertiary care hospital

“…Skin tags, or acrochordon or fibroepithelial polys, are common benign skin outgrowths. 22 In our study, seven participants had skin tags, and five (71.42%) had a positive family history of skin tags. This result is also seen in other studies.…”

Stability Profile and Clinical Evaluation of an Innovative Hydrogel Containing Polymeric Micelles as Drug Delivery Systems with Oregano Essential Oil against Fibroepithelial Polyps

“…Currently, the effective removal of FPs involves minimally invasive techniques such as cryosurgery, cauterization, surgical excision, and laser therapy. While non-invasive treatments available over the counter have piqued the interest of patients, their clinical efficacy has not been plainly established yet [ 17 ].…”
