Enhanced Effectiveness of Onabotulinum Toxin A in Combination With Definisse KP1 Eye Contour Cream for Upper Face Rejuvenation: A Case Series
Abstract
BACKGROUND: Among antiaging treatments, botulin toxin A injection is one of the most widely used. KP1 (Serpine A1-III) is a recently developed bioactive peptide that increases collagen type I by enhancing its synthesis and preventing its degradation.
AIMS: This case series described the combinatorial effect of onabotulinum toxin A injection with Definisse KP1 eye contour cream application in the treatment of skin aging in the upper third of the face.
PATIENTS/METHODS: Adult subjects with moderate to severe dynamic wrinkles who received onabotulinum toxin A combined with Definisse KP1 eye contour cream (Onabotulinum toxin A + KP1 group, hereinafter referred to as + KP1 group) or onabotulinum toxin A alone (Control group) were included in the analysis. The following variables were measured: severity of the disorder, skin hypersensitivity, erythema, oedema, periocular wrinkles, skin quality, hydration-creepiness, and tightness; each parameter was evaluated in both eyes 4 weeks posttreatment.
RESULTS: Data from 22 in the + KP1 group and 19 in the Control group were collected. In the + KP1 group, all variables improved, except for eye erythema and eye oedema. Conversely, in the Control group, only eye impairment severity and periocular wrinkles improved from baseline. In the satisfaction questionnaire, the overall evaluation of the protocol achieved higher scores in the + KP1 group than in the Control group.
CONCLUSIONS: From this case series, the application of Definisse KP1 eye…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
