What was done
Authors conducted a systematic review across PubMed, Scopus, and Web of Science searching for clinical trials and observational studies that evaluated the proactive use of botulinum toxin (BoNT) to delay facial aging in younger, pre-symptomatic populations.
What was found
The abstract reports no quantitative values, effect sizes, or counts. Qualitatively, proactive BoNT application was associated with reduced muscle hyperactivity, delayed formation of dynamic wrinkles, minimized progression of static lines, and potential dermal collagen remodeling on histology, although data remain heterogeneous.
Why it matters
This paper assesses the evidence for the increasingly common practice of preventative neurotoxin injections in younger individuals before wrinkles become static, finding theoretical promise but a need for standardized protocols.
Limits
The abstract omits the number of included studies and participants (n = ?). The evidence base is constrained by study design heterogeneity, reliance on observational and histological data, and a lack of established long-term safety and efficacy data.
