Treatment Overview
Under Eye Firming with Thermage FLX is a non-invasive radiofrequency (RF) procedure performed in Korea to tighten and rejuvenate delicate under-eye skin. Thermage FLX delivers controlled monopolar RF energy deep into the dermis, stimulating collagen production and remodeling to reduce fine lines, mild sagging, and under-eye laxity.
Unlike surgical eyelid procedures, this treatment provides subtle, natural lifting without incisions or downtime. When combined with Juvelook skin boosters, it enhances hydration, elasticity, and skin quality for a refreshed, youthful under-eye appearance.
Purpose & Benefits
- Tightens Under-Eye Skin: Firms sagging and loose skin beneath the eyes.
- Reduces Fine Lines: Smooths crow’s feet and under-eye wrinkles.
- Collagen Stimulation: Promotes long-term improvement in elasticity and resilience.
- Natural Rejuvenation: Gradual lifting without altering facial expression.
- Non-Invasive: Safe, minimally uncomfortable, and no recovery downtime.
- Synergy-Ready: Can be combined with Juvelook, thread lifts, or RF microneedling for enhanced results.
