Treatment Overview
Thermage FLX is a non-invasive radiofrequency (RF) skin tightening treatment that delivers controlled heat into the dermis and subcutaneous tissue to stimulate collagen remodeling and elastin production.
For dark circles, Thermage FLX is particularly effective for patients whose under-eye concerns are caused by skin laxity, thinning, or fine wrinkles. By firming and thickening the delicate under-eye skin, it reduces the appearance of shadows, puffiness, and crepey texture.
In Korea, Thermage FLX is often combined with laser toning, Rejuran i, exosomes, or skin boosters for a holistic approach to dark circle correction.
Purpose & Benefits
- Tightens Skin: Firms loose or sagging under-eye skin.
- Boosts Collagen & Elastin: Improves dermal thickness and reduces transparency of blood vessels.
- Smooths Wrinkles: Reduces fine lines and crepey under-eye texture.
- Lifts Under-Eye Area: Mild lifting effect softens shadows and puffiness.
- Non-Surgical & Safe: No downtime, effective for most skin types.
- Synergy: Works well with fillers, regenerative injectables, or laser brightening.
