Double Chin Ultherapy Lifting Effects and Process: How to Define a Blurry Jawline
Discover the principles and effects of Ultherapy lifting to resolve concerns about a sagging jawline and double chin caused by aging. 345 Dermatology Clinic provides a professional treatment guide, covering how to target the SMAS layer using High-Intensity Focused Ultrasound (HIFU), synergistic treatment combinations, and essential precautions.

What is Double Chin Ultherapy? The Principles of High-Intensity Focused Ultrasound
As we age, skin elasticity naturally decreases, causing the lower face to sag and the jawline to become blurry. In particular, a double chin, which is often more prominent from the side than the front, is a major factor that can make one's impression look dull. To resolve these concerns, there has been growing interest recently in the non-surgical method of Ultherapy lifting.

Ultherapy is a device that uses High-Intensity Focused Ultrasound (HIFU) to create thermal coagulation points at specific depths within the skin. The Ultherapy Prime used at 345 Dermatology Clinic is an upgraded version designed to target the jawline and double chin areas more precisely than previous devices, helping to deliver energy while minimizing damage to surrounding tissues.
Layer-by-Layer Targeting for Jawline Improvement: The Importance of the SMAS Layer
For successful double chin lifting, it is necessary to improve the deep support structures of the skin rather than simply pulling the skin surface. Ultherapy uses three types of genuine tips—1.5mm, 3.0mm, and 4.5mm—to evenly deliver energy not only to the epidermis and dermis but also to the fat layer and the SMAS (Superficial Musculoaponeurotic System) layer.

In particular, for double chin improvement, the 4.5mm tip is primarily used to contract the fascial layer, while the 3.0mm tip is used to increase the elasticity of the fat and dermal layers. Looking at actual cases, you can expect changes where unnecessary volume under the chin is reduced, and the collapsed lower facial line becomes noticeably lighter and more defined.
Candidates for Double Chin Lifting and Expected Effects
Ultherapy is suitable for those who prefer a natural lifting effect that enhances their original contours rather than artificial changes. Specifically, it is recommended for individuals with the following concerns:
- Those whose jawline has become blurry, making it difficult to distinguish between the front and side profiles
- Those who have a visible double chin due to sagging skin
- Those who have experienced a rapid loss of elasticity in the lower face due to aging
- Those who want lifting through a non-invasive method without incisional surgery

Elasticity Synergy Combinations to Maximize Effects
While excellent changes can be expected with Ultherapy alone, combining it with other treatments according to your individual skin condition can produce synergistic effects.
- Thermage FLX: Enables a complex lifting (Ulthermage) that fills the skin surface with dense elasticity using Radio Frequency (RF) energy.
- Skin Botox: Improves fine wrinkles on the superficial layer of the skin and smooths out the skin texture.
- Juvelook / Rejuran: Promotes self-collagen regeneration to increase internal density and restore fundamental skin health.
345 Dermatology Clinic's Principles for Safe Procedures
For lifting procedures, precisely analyzing each individual's facial fat volume and skin thickness must be the priority. At 345 Dermatology Clinic, we establish a customized treatment plan after analyzing the depth of wrinkles and pore conditions that are difficult to see with the naked eye using the Mark-Vu skin diagnosis system.

In addition, we operate a thorough disinfection and sterilization system throughout the entire procedure process, and we strive for rapid recovery and high patient satisfaction through a systematic follow-up observation program after the treatment. If you are concerned about a heavy impression caused by a double chin, we recommend determining the most appropriate number of shots and intensity for you through a precise diagnosis.
