Is Platelet-Rich Fibrin (PRF) injection effective for treating under eye bags?

Platelet-Rich Fibrin (PRF) for Under Eye Bags

PRF injections are a promising treatment option for under eye bags, showing favorable outcomes in terms of safety and effectiveness for periorbital rejuvenation, with studies demonstrating improvements in skin condition around the eyes. 1

Effectiveness of PRF for Under Eye Bags

• PRF demonstrates significant improvements in periocular wrinkles, periorbital hyperpigmentation, skin thickness, and overall skin freshness in the under-eye area 1
• PRF has emerged as a promising therapeutic modality among non-invasive facial rejuvenation treatments, with most studies reporting favorable outcomes in skin texture, tone, and elasticity 2
• One comparative study showed PRF's superiority over PRP (Platelet-Rich Plasma) specifically for canthal smoothness and wrinkles at month 3, suggesting PRF may be a viable alternative for periorbital rejuvenation 2
• As an autologous material derived from a person's own platelets, PRF offers a favorable safety profile compared to chemical fillers, which many injectors avoid in the periorbital area due to safety concerns 1

Treatment Protocol for PRF Under Eye Injections

• Three treatments are typically required for adequate skin rejuvenation, spaced with a minimum 21-day interval, with one maintenance treatment every 6 months thereafter 2
• For safe administration in the delicate under-eye area, it is recommended to use small gauge needles (30G), lower depth settings (0.25 mm) with microneedling devices, or a 22G × 2 inches cannula when using Alb-PRF formulation 1
• PRF preparation requires specific centrifugation protocols without anticoagulants, which differs from PRP preparation 2
• Patients should be advised on maintaining a good home care routine and adequate sun protection to enhance and maintain results 2

Safety Considerations and Side Effects

• PRF treatments are generally well-tolerated with minimal side effects 2
• Patients should be warned about potential temporary side effects including bruising and swelling, which typically resolve with time 1
• Unlike hyaluronic acid fillers which carry risks of vascular complications in the periorbital area, PRF offers a safer alternative due to its autologous nature 1, 3
• The procedure is minimally invasive with virtually pain-free administration when performed correctly 4

Comparative Effectiveness

• While traditional treatments like hyaluronic acid fillers can be effective for tear troughs 3, they may not adequately address under-eye bags without creating lumps or irregularities
• PRF shows promise as an alternative to surgical approaches for addressing under-eye bags 1
• Other non-surgical options like poly-d,l-lactic acid injections 5 or epidermal growth factor serums 6 have shown some effectiveness, but PRF offers the advantage of using the patient's own biological material
• PRF can be particularly beneficial for patients with combined issues of tear troughs and mild to moderate under-eye bags 4, 7

Limitations and Considerations

• Protocols for PRF in skin rejuvenation remain variable regarding preparation, dosing, and number of treatment sessions 2
• Further high-quality double-blind randomized controlled trials with standardized outcome measures are needed to optimize this treatment approach 2, 1
• PRF may not be as effective for severe eye bags that require surgical intervention 7
• Patient selection is crucial - those with significant skin laxity or pronounced orbital fat herniation may require combination treatments or surgical approaches 7
