What it treats
- Mild to moderate laxity and fine wrinkling of the upper and lower eyelid skin, in patients reluctant to undergo blepharoplasty (PMID 17598845).
- Dermatochalasis graded by severity: the degree of improvement after energy-based treatment depended on baseline severity, and the authors advised the technique for mild disease only, with surgery giving better results for more advanced grades (PMID 39694894).
- Periorbital wrinkles and skin laxity of the outer corner (crow's feet), lower lid, and infrabrow region, distinct from the fold-forming and fat-related changes that blepharoplasty addresses directly (PMID 24833451), (PMID 28095539).
- Current nonsurgical options for periorbital skin excess and volume loss include dermal fillers, deoxycholic acid, lasers, plasma exeresis, platelet-rich plasma, and polydioxanone threads (PMID 36969996).
How it is done
Radiofrequency (RF)
- Nonablative RF heats the dermis without breaking the skin surface; the first reported lower-eyelid use was a single 10-minute session under topical anesthesia only (PMID 14756637).
- Monopolar RF through a small tip was tested in a multicenter trial requiring no cutaneous anesthesia (PMID 17163476); a companion animal, ex vivo, and in vivo safety study found no eyelid or eye injury when used properly (PMID 17598844).
- Eye protection is standard: haptic scleral contact lenses (PMID 17598845), or opaque plastic eye shields with a temperature-controlled RF device that tracks tissue temperature by infrared imaging (PMID 28095539).
- Thermage heats the dermis and deep fibrous septae through a cooled epidermis, remodeling collagen in the jowl, neck, and eyelids (PMID 19309652).
- Bipolar RF with fractional photothermolysis has treated Asian lower-eyelid and crow's-feet wrinkling (PMID 25234835); a 2025 study used a monopolar tip for upper eyelid tightening specifically in Asian patients (PMID 41402632).
- Newer devices sequence two RF frequencies: a dual-frequency monopolar system pairs 6.78 MHz and 2 MHz energy for deeper reach (PMID 42611100), and a sequential monopolar-bipolar pulsed tip treats the upper and lower lid and lateral canthus (PMID 41710528).
Microneedle fractional radiofrequency (MFR/RFMN)
- MFR passes insulated or noninsulated microneedles into the dermis and delivers RF at the needle tip, creating vertical injury channels that trigger new collagen without surface ablation (PMID 37830418).
- Needle depth matters: with long (1.5 mm) versus short (0.8 mm) needles on opposite sides, only the long-needle side showed significant wrinkle-score improvement (PMID 31500484).
- Device variants include an RF hydro-injector pairing microneedle RF with a hyaluronic acid injection (PMID 34208109), a negative-pressure fractional system (PMID 38013586), and a dual-depth 25-pin device delivering energy to 1.5 mm and 1.0 mm in one insertion (PMID 42467384).
- MFR has been tested against fractional erbium-glass 1,565 nm laser for baggy lower eyelids, and paired with topical polynucleotides after treatment (PMID 34812096), (PMID 35501660).
- MFR delivered immediately before botulinum toxin type A injection reduced the toxin's effect for about 3 days, an interaction relevant to timing combined treatments (PMID 37195395).
Plasma (fibroblast) devices
- Plasma devices generate an electrical arc between the tip and the skin, without contact, that sublimates the epidermis and contracts the dermis; systems include the DAS Medical plasma blade (PMID 30927022) and devices marketed for "plasma exeresis" or plasma radiofrequency ablation (PMID 31535742).
- A microplasma applicator was first tested on pig skin, producing dose-dependent ablation and dermal coagulation with the expected healing response before clinical use (PMID 39913226).
- A 2021 review calls the shift toward these techniques a "new era" in upper eyelid rejuvenation (PMID 33602571).
- A plasma scalpel has also been used for posterior, nonincisional Müller's muscle sublimation for mild-to-moderate ptosis, distinct from the Müller muscle-conjunctival resection described in blepharoptosis repair (PMID 40528246).
Fractional CO2 and erbium laser resurfacing and chemical peels of the eyelid are covered in eyelid and periorbital skin resurfacing and not repeated here.
Results and evidence
Radiofrequency
- In a multicenter trial, nearly 9 in 10 patients had upper eyelid tightening, a similar share had less hooding, and about 7 in 10 had lower eyelid tightening; more energy did not give a better result (PMID 17163476).
- In a pilot study, most upper lids and about two thirds of lower lids showed at least 25% tightening by expert rating at 6 months (PMID 17598845).
- In Asian patients after a single session, most reported more than 50% improvement at 2 months and at 6 months, and the brow rose about 1 mm (PMID 41402632).
- Dual-frequency monopolar RF produced lateral volume gain, medial volume reduction, progressive brow and lid elevation, and improved patient-reported scores, though the authors call the findings preliminary (PMID 42611100).
- Sequential monopolar-bipolar pulsed RF gave moderate to marked improvement by month 5 in a very small case series (PMID 41710528).
Microneedle fractional radiofrequency
- For baggy lower eyelids, MFR and fractional erbium-glass laser gave similar reductions in bulge and orbital fat depth, with about half of patients satisfied with both (PMID 34812096).
- After 4 sessions, facial wrinkle scores fell by about half (PMID 39418172).
- After 3 sessions, wrinkle scores fell by about a third by week 24, about 9 in 10 patients were satisfied or very satisfied, and downtime averaged 1.5 days (PMID 42467384).
- Wrinkle reduction varied widely between patients: on average about a quarter under the eyes and about a third at the crow's feet (PMID 42289104).
- In women aged 60 and older, MFR improved skin cell health on histology and gave greater clinical improvement than microneedling alone (PMID 40419589).
- RF microneedling can be combined with poly-L-lactic acid, polynucleotides, platelet-rich plasma, or trichloroacetic acid to enhance outcomes (PMID 40537669).
Plasma devices
- After 3 sessions, laxity ratings improved and confocal microscopy showed collagen reorganized into long, straight fibers (PMID 28930794).
- After 2 sessions, the amount of excess eyelid skin fell by about 2.5 mm at 6 months and about 2 mm at 12 months, and about 8 in 10 patients and clinicians were satisfied at 12 months (PMID 30927022).
- After 3 sessions in women, laxity ratings improved in 9 in 10 patients and the distance from lid margin to crease increased significantly (PMID 32698635).
- In a large descriptive series, the upper eyelid was the most frequently treated site, the lower eyelid next, and about half of patients were extremely satisfied (PMID 33841619).
- A microplasma pilot found improvement on dermatochalasis and global improvement scales after 1 to 2 sessions, with minimal adverse effects (PMID 39913226).
- Satisfaction was highest at day 7 and declined by day 30; the authors called overall satisfaction "questionable" once willingness to repeat and expectations were factored in (PMID 33252188).
Risks and complications
- RF eye-protection studies report minimal adverse events: one subject had transient corneal surface defects that resolved within hours (PMID 17598845); an animal, ex vivo and in vivo safety study found no eyelid or eye injury with proper technique (PMID 17598844).
- MFR adverse events across trials are mostly transient redness and swelling; one negative-pressure MFR trial recorded a single case of postinflammatory hyperpigmentation, which resolved (PMID 38013586).
- MFR delivered immediately before botulinum toxin injection blunted the toxin's effect for about 3 days, a timing consideration when combining treatments (PMID 37195395).
- A case report describes bilateral alkali chemical eye injury with corneal epithelial loss after EMLA anesthetic cream was inadvertently exposed to both eyes before a salon "plasma fibroblast skin tightening" treatment; the patient recovered with topical antibiotics (PMID 32831067).
- Plasma (fibroblast) pens sold for home or non-medical use are often not FDA-regulated; a TikTok content analysis found most posts came from lay users or self-proclaimed specialists rather than clinicians, with reported risks of dyspigmentation, scarring, and mechanical burns, and very few posts were safety warnings (PMID 35500136).
- No irreversible complications occurred in a plasma blade series, but mean procedural pain was about 4.5 of 10, and about 1 in 4 patients needed additional analgesia with inhaled nitrous oxide-oxygen (PMID 30927022).
Recovery
- The first nonablative RF technique required no postoperative care; patients resumed normal routines immediately after a single 10-minute session (PMID 14756637).
- Cutaneous anesthesia was not required in the multicenter monopolar RF trial (PMID 17163476).
- Dual-depth microneedle RF took about 7 minutes per session with about 1.5 days of downtime, and adverse events were limited to transient mild redness and swelling (PMID 42467384).
- After plasma blade treatment, eyelid swelling and itching were the symptoms most reported at 7 and 30 days respectively (PMID 33252188).
Combined procedures
- The plasma blade technique "can be usefully and successfully associated with surgery," per its outcomes study, positioning it as a possible blepharoplasty adjunct rather than only a stand-alone alternative (PMID 30927022).
- A nonsurgical review lists fillers, deoxycholic acid, lasers, plasma exeresis, platelet-rich plasma, and polydioxanone threads as complementary options addressing different problems (volume loss, fat excess, skin laxity), not one device replacing the others (PMID 36969996).
- Surgical excision of eyelid skin, muscle, and fat is covered separately in upper blepharoplasty.
Current questions
- Severity threshold: a 2024 study found microplasma suitable for mild dermatochalasis (grades 0-1), with surgery giving better results for more advanced grades, a distinction marketing does not always make clear (PMID 39694894).
- Durability of satisfaction: short-term satisfaction after plasma treatment was high in several series (PMID 30927022), (PMID 32698635), but one study found satisfaction and willingness to repeat declined between 7 and 30 days (PMID 33252188).
- Study design: most RF, MFR, and plasma studies for the eyelid are small, self-controlled or split-face; none identified compares an energy device head-to-head against blepharoplasty in the same patients.
- Regulatory gap: fibroblast pens are often sold and used outside medical settings without FDA regulation, and safety warnings were rare compared with promotional social-media content (PMID 35500136).
- Newer dual-frequency and sequential RF devices report preliminary results from very small single-arm series; one report's authors explicitly caution their observations are anecdotal, not evidence-based conclusions (PMID 41523730).
- Plasma-based Müller's muscle sublimation for ptosis is reported in a single small case series and has not been compared with standard ptosis repair (PMID 40528246).
Terms
- Dermatochalasis: excess, lax eyelid skin, the main target of these techniques (PMID 39694894).
- Nonablative radiofrequency (NARF): RF energy that heats the dermis to contract collagen without breaking the skin surface (PMID 14756637).
- Monopolar / bipolar RF: RF delivery through one treatment electrode (monopolar) or two adjacent electrodes (bipolar), which changes the depth and pattern of heating (PMID 25234835).
- Microneedle fractional radiofrequency (MFR / RFMN): RF energy delivered through fine needles inserted into the dermis, combining mechanical microinjury with thermal injury (PMID 37830418).
- Insulated vs noninsulated microneedles: insulated needles concentrate RF energy at the needle tip and spare the epidermis; noninsulated needles heat the full needle track including the skin surface (PMID 31500484).
- Plasma exeresis (plasma skin regeneration): a technique using an electrical arc between a device tip and the skin, without direct contact, to sublimate the epidermis and contract the dermis (PMID 28930794).
- Fibroblast pen (plasma pen): a handheld plasma-arc device marketed for skin tightening, sometimes sold for non-medical or home use (PMID 35500136).
- Facial laxity rating scale (FLRS): a scored scale for skin laxity severity used to grade dermatochalasis before and after treatment (PMID 32698635).
- Global Aesthetic Improvement Scale (GAIS): a standard scale on which a physician or patient rates overall cosmetic improvement after treatment (PMID 34208109).
- Senescent fibroblast: an aged dermal cell that has stopped dividing and contributes less new collagen; some energy-based treatments aim to reduce these cells and increase non-senescent, collagen-producing fibroblasts (PMID 40419589).
