Thermage FLX in Seoul, Korea: Firm and Smooth, Face-Wide

———— ✦ ————

Rather than lifting a single spot, Thermage FLX firms the whole face. Radiofrequency heat awakens collagen for skin that looks smoother and feels more resilient.

The Device

Radiofrequency for Overall Elasticity

———— ✦ ————

Thermage FLX delivers radiofrequency (RF) energy to the dermis, heating it to stimulate collagen contraction and regeneration. It works from the dermis down to the subcutaneous fat, across a wide area, for an overall tightening effect.

The forehead, eye area, cheeks and jawline all differ in thickness and sensitivity. BYUS plans energy levels and shot counts separately for each area so treatment is tailored, not uniform.

Because collagen rebuilds over time, changes may appear over weeks to months, and results vary.

BYUS Points

Smart Tightening, Not Over-Tightening

———— ✦ ————

Lifting or Elasticity?

These concerns look alike but come from different layers, so BYUS identifies which you have first.

Energy by Area

Energy is adjusted for each zone's thickness and sensitivity.

Natural Elasticity

The goal is resilient skin, not unnecessary tightness.

Pairs With Ulthera

Thermage FLX and Ulthera Prime can be planned together when both layers need care.

Who It Suits

Is Thermage FLX for You?

———— ✦ ————

  • Skin elasticity is lower than it used to be
  • Fine lines are increasing and skin looks thinner
  • Skin feels generally loose
  • Elasticity concerns around the eyes and forehead
  • You want regular, ongoing care for skin aging

Choosing a Device by Depth
