Thermage FLX in Los Angeles by Dr. K. Charles Kim is a non-invasive radiofrequency treatment that delivers volumetric heating to the deep dermis, stimulating collagen contraction and remodeling for visible skin tightening. Thermage FLX is particularly valuable for tightening on the face, eyes, neck, abdomen, and body — areas where laxity does not yet justify surgery but visibly responds to thermal stimulation. Dr. Kim's clinical team is experienced in calibrating Thermage to each patient's skin type and concern.

The Thermage FLX handpiece delivers monopolar radiofrequency energy across the treated zone in calibrated passes. Surface cooling protects the epidermis while heating the deeper dermis to therapeutic temperature. Vibration during the pulse improves patient comfort and accelerates treatment time compared to prior generations. Eye, face, and body tips deliver appropriately scaled energy. A single session typically produces visible improvement that continues to develop over months.

Day 1: Mild redness and warmth that resolve within hours; immediate return to normal activity.

Weeks 2–8: Initial tightening becomes visible.

Months 3–6: Full collagen-driven contraction produces final result; effects typically last 1–2 years, with maintenance recommended annually.

Frequently Asked Questions

Thermage FLX is considered safe for all skin types and tones, as radiofrequency energy targets deep tissue without relying on light absorption by pigment. This makes it a versatile option across diverse patients. Dr. Kim's practice evaluates each patient to confirm suitability.

Thermage FLX can treat the face, eyes, neck, and body areas prone to laxity, including the jowls, under-eye region, and abdomen. It is versatile for smoothing and firming skin. Dr. Kim's practice identifies the areas best suited to your goals.

Thermage FLX uses radiofrequency energy to heat the deeper layers of the skin, tightening existing collagen and stimulating new collagen production for a firmer, smoother surface. A cooling system protects the skin during treatment. The result is gradual, non-surgical tightening with no downtime.

Some skin tightening may be visible soon after Thermage FLX, while the fuller results develop gradually over 2 to 6 months as collagen rebuilds. The improvement is natural and progressive. Dr. Kim's team monitors your results over time.

Thermage FLX is typically a single-session treatment, with collagen-driven tightening continuing to develop over the following months. Many patients enjoy results for a year or more before considering a maintenance session. Dr. Kim's practice advises on timing based on your skin.

A Thermage FLX session generally takes 30 to 90 minutes depending on the area treated, and is completed in one visit with no downtime. You can return to daily activities right away. Dr. Kim's practice provides a time estimate tailored to your treatment.

Thermage FLX is designed for comfort, using a vibration feature and brief cooling bursts with each pulse of radiofrequency energy, so most patients experience only a warming sensation. It is well tolerated without anesthesia. Dr. Kim's team ensures a comfortable treatment experience.
