Why Lisoom

Overview Conservative RF Lifting Designed for Thin Neck Skin

Thermage for Neck Lines is a non-surgical lifting treatment that applies Thermage FLX, a monopolar radiofrequency (RF) device operating at about 6.78MHz, to neck skin, which is thinner than facial skin.
It heats the entire dermis uniformly over broad areas to induce immediate collagen contraction and new collagen synthesis, playing a supporting role in gradually improving horizontal lines and reduced dermal firmness.
Because neck skin is thin and lies close to the thyroid gland and nerves, the intensity is designed at least one step more conservatively than for the face; results vary between individuals, so the intensity and treatment area are determined during the consultation.

How Thermage for Neck Lines Works

Neck Anatomy SUTURE guide image

SutureNeck Anatomy

The neck is an area where the epidermis, dermis, platysma muscle, and deep fascia are gathered within a very thin layer. The thyroid gland and airway lie in the midline, and the carotid artery and branches of the facial nerve run along the sides. Carrying over facial intensity settings narrows the safety margin, so the treatment area and intensity must be redesigned.

Thin Dermis Thyroid Avoidance Nerve Awareness
Horizontal Lines HYBRID guide image

HybridHorizontal Lines

Horizontal neck lines are creases etched by a combination of dermal collagen loss and repeated flexion. Thermage heats the entire dermis uniformly to induce immediate contraction and gradually reduces the depth of the lines through new collagen synthesis. Very deep horizontal lines often require a combination with fillers or skin boosters.

Horizontal Lines Dermal Contraction Combination Advised
Vertical Bands PARTIAL guide image

PartialVertical Bands

Vertical bands are caused by the thickness and activity of the platysma muscle itself. The RF energy of Thermage is effective for stimulating the superficial dermis, but it is not a treatment that reduces the muscle itself, so a combination with Botox is recommended for thick bands. We directly check the pattern of banding during the consultation and then decide on a suitable combination.

Under-Chin Contour INCISION guide image

IncisionUnder-Chin Contour

Submental sagging results from skin sagging and fat distribution acting together. Thermage contributes to refining the superficial contour and to dermal contraction, but it has limits for a double chin with substantial fat accumulation, where a fat-reduction treatment or facelift surgery should be considered as well. At RESUM, we assess the patient's submental structure component by component during the consultation and explain accordingly.

OUR PRINCIPLE

Core Values
The Principles RESUM Keeps

The neck is an area where carrying over facial settings as they are poses considerable risk. At RESUM, Dr. Jin-Young Kim, who performs the treatment, checks skin thickness, thyroid position, platysma thickness, and posture in a 1:1 consultation and then redesigns the treatment area and energy intensity. Our principle is to treat conservatively within an academically validated range.

Thin Skin Design

Thin Skin Design

Planning for Thin Skin

After directly assessing neck skin thickness during the consultation, we set the intensity at least one step more conservatively than the facial standard. Drawing on clinical experience accumulated in anti-aging dermatology, we decide how to distribute intensity by area. Even in the same patient, the midline, the sides, and the submental area are treated at different intensities.

Nerve Safe

Nerve Safe

Nerve & Thyroid Safety

The midline, where the thyroid gland lies, is excluded from the treatment area, and only a lateral approach is used. Along the mandibular border, where branches of the facial nerve pass, we use only short pulses at a conservative intensity and proceed while checking patient feedback in real time. Our principle is not to narrow the safety margin.

Honest Combination Advice

For deep horizontal lines, thick platysma bands, and a severe double chin that are difficult to address with Thermage alone, we honestly explain combinations with other treatments such as Botox, fillers, fat-reduction treatments, and facelift surgery. We do not tell patients that a single device can produce every change.

POINT 04 Q&A

Can the Neck Be Treated at the Same Intensity as the Face?

First, the neck is thinner than the face, so the intensity must be lowered.

First, the neck is thinner than the face, so the intensity must be lowered.

Neck skin is thinner on average than facial skin and lies close to nerves and blood vessels, so applying facial intensity as is can increase irritation and risk. After checking skin thickness during the consultation, we design the plan at least one step more conservatively than the facial standard.

Second, deep lines and bands may require a combination.

Second, deep lines and bands may require a combination.

Thermage helps refine firmness throughout the dermis, but for very deep horizontal lines or thick platysma bands, a combination with other treatments such as fillers or Botox is often more suitable. We check the pattern during the consultation and then explain the appropriate approach.

Third, posture-related sagging is not corrected by treatment alone.

Third, posture-related sagging is not corrected by treatment alone.

For posture-related sagging such as forward head posture, combining treatment with posture management and exercise helps stabilize the result. We explain separately what the treatment can address and what needs to be addressed through posture management; results vary between individuals.

POINT 03 Features

Features of Thermage for Neck Lines

How Monopolar Radiofrequency Works

How Monopolar Radiofrequency Works

Thermage delivers monopolar radiofrequency at about 6.78MHz throughout the dermis of the neck, heating it uniformly over broad areas. The heat generated raises the temperature of the dermis, causing immediate collagen contraction and then inducing new collagen synthesis, while the surface is protected by cooling. Because the neck has a thinner dermis than the face, the intensity is lowered even with the same RF. Broad-area heating of the entire dermis · Immediate collagen contraction + new collagen synthesis · Epidermal protection through surface cooling · Conservative intensity at least one step lower than for the face

AccuREP and CPT Technology

AccuREP and CPT Technology

The AccuREP algorithm measures tissue impedance in real time with every pulse and automatically adjusts the energy output for each area. CPT (Comfort Pulse Technology) adds vibration and cooling to reduce discomfort during treatment. On the neck, the midline where the thyroid gland lies is excluded, and a safety margin is secured by an approach that detours to the sides. Real-time impedance measurement and automatic energy adjustment · Treatment comfort through vibration and cooling · Thyroid midline excluded, lateral approach · Conservative treatment with short pulses over nerve branches

NOTICE

Precautions
Aftercare & Precautions

N · 01 The neck has a thinner dermis than the face and lies close to nerves and blood vessels, so the intensity is designed at least one step lower than the facial standard.
N · 02 The midline of the neck, where the thyroid gland lies, is excluded from treatment, and a safety margin is secured by an approach that detours to the sides.
N · 03 Because of the nature of monopolar radiofrequency, patients with implanted electrical devices (such as a pacemaker) or a metal implant around the neck may be excluded from treatment.
N · 04 Very deep horizontal lines and thick platysma bands are difficult to address with Thermage alone, and a combination with Botox, fillers, or other treatments may be more suitable.
N · 05 Posture-related sagging, such as forward head posture, is not corrected by treatment alone; combining it with posture management and exercise helps stabilize the result.
N · 06 For about 1 week after treatment, we recommend cutting back on rubbing the neck firmly and on activities that heat it, such as saunas and hot compresses.
N · 07 Results vary with neck skin thickness and the pattern of lines, and the intensity and treatment area are determined in a consultation with Dr. Jin-Young Kim.

Doctor's Note

The neck is thin and always in motion, and nerves and blood vessels lie close by. The intensity used on the face must not simply be carried over. The most important step is redesigning the plan within an academically validated, conservative intensity range. At RESUM, the director in charge of the treatment personally checks skin thickness and thyroid position in the consultation and then adjusts the intensity for each zone.

FREQUENTLY ASKED

FAQ
Frequently Asked Questions

We have compiled the questions patients ask most often before a consultation.

Thermage for Neck Lines is a non-surgical lifting treatment in which 6.78MHz monopolar capacitive radiofrequency (CRF) heats the entire dermis of the neck uniformly, inducing immediate collagen contraction and new collagen synthesis. The epidermis is protected by real-time cooling, and the midline area where the thyroid gland lies is excluded from the treatment area. Treatment proceeds with a lateral approach to secure a safety margin.
For the neck alone, it takes about 30-50 minutes, with time for applying topical anesthesia (30-40 minutes) added separately. When performed together with the face, it takes about 1-2 hours including anesthesia time. Thanks to the vibration and cooling of the FLX generation, treatment time has been shortened.
Some change is visible right after treatment from the immediate contraction of dermal collagen, and new collagen synthesis then builds up gradually over 4-6 months. Because the neck moves frequently, we recommend allowing a longer period than for the face before evaluating the result.
Because there are no incisions, you can return to daily activities right after treatment. Slight swelling and redness may be present for about 1-3 days and, in rare cases, continue mildly for up to 1-2 weeks. No separate rest period is needed.
Temporary swelling, redness, and tightness may occur right after treatment and settle within 1-2 weeks. In rare cases, mild bruising may develop, and because the neck is a thin area, treatment is performed at a more conservative intensity than for the face. If pain or swelling persists asymmetrically, we check it in a consultation.
The cost varies with the number of shots and the extent of treatment (neck alone or combined with the face). There is no single fixed price; the cost is calculated from the treatment plan designed for each patient's condition. Exact details are explained during your consultation.
