Botox and Fillers Deliver Youthful Perioral Results Without Surgery
A 2025 review reveals how neurotoxins and dermal fillers can effectively reverse age-related changes around the mouth with minimal downtime.
Summary
A comprehensive 2025 review from Penn State Health examines how neurotoxins and dermal fillers can rejuvenate the perioral region — lips, chin, nasolabial folds, and surrounding skin — without surgery. Neurotoxins such as Botox, Dysport, Xeomin, Jeuveau, and Daxxify relax expression muscles to smooth wrinkles and elevate drooping corners of the mouth. Dermal fillers including hyaluronic acid, calcium hydroxyapatite, and poly-L-lactic acid restore volume lost to aging. The authors emphasize that ideal candidates are adults with age-related wrinkles or volume loss seeking minimally invasive options. Precise anatomical knowledge and careful patient selection are highlighted as essential for achieving natural-looking, youthful outcomes with limited recovery time.
Detailed Summary
The lower face ages visibly and often earlier than other regions, yet it receives comparatively less attention in aesthetic medicine literature. This 2025 review from Penn State Health addresses that gap by systematically examining the role of neurotoxins and dermal fillers in perioral rejuvenation — a clinically important topic as demand for nonsurgical facial procedures continues to rise globally.
The perioral region encompasses the lower third and middle three-fifths of the face, including the lips, surrounding skin, chin, muscles of facial expression, and underlying bony structures. Age-related changes here — including perioral rhytids, volume deflation, downturned oral commissures, and deepening nasolabial and marionette lines — significantly contribute to an aged appearance and are increasingly addressable without surgery.
Neurotoxins covered include the five FDA-approved botulinum toxin products: Botox, Dysport, Xeomin, Jeuveau, and Daxxify. These agents relax hyperactive muscles responsible for vertical lip lines, downturned mouth corners, dimpled chin texture, and gummy smiles. The lip flip technique — using small toxin doses above the upper lip — is highlighted as a nuanced, low-risk approach to subtle lip enhancement. Dermal fillers including hyaluronic acid, calcium hydroxyapatite, and poly-L-lactic acid are reviewed for volumizing lips, softening nasolabial folds and marionette lines, and augmenting chin projection.
The review underscores that outcomes depend heavily on anatomical expertise, precise injection technique, and individualized patient selection. Combining neurotoxins with fillers in a layered approach often yields superior, synergistic results.
For longevity-focused readers, this is relevant because facial aging is a visible biomarker of systemic aging, and maintaining aesthetic confidence has documented psychosocial health benefits. However, as a narrative review without a meta-analytic framework, evidence grading is limited.
Key Findings
- Five neurotoxins — Botox, Dysport, Xeomin, Jeuveau, Daxxify — effectively reduce perioral wrinkles and improve oral commissure position.
- Hyaluronic acid fillers remain a primary tool for lip volumization and smoothing nasolabial and marionette lines.
- The lip flip technique offers subtle upper lip enhancement with minimal toxin doses and low risk.
- Combining neurotoxins and fillers produces synergistic rejuvenation superior to either treatment alone.
- Deep anatomical knowledge and precise injection technique are critical for safe, natural-looking perioral outcomes.
Methodology
This is a narrative clinical review published in Facial Plastic Surgery (2025), summarizing existing evidence and expert technique on neurotoxin and filler use in the perioral region. No original clinical trial data or meta-analysis was conducted. The review is authored by otolaryngology/head-and-neck surgery specialists at a major academic medical center.
Study Limitations
As a narrative review rather than a systematic review or meta-analysis, evidence quality and bias risk are not formally assessed. The abstract does not detail complication rates, longevity of results, or comparative efficacy between products, limiting actionable clinical specificity.
