Ultrasound HIFU Facelift
A comprehensive and clinical guide to facial and neck hypnotherapy
A thorough examination of the mechanism of action of focused ultrasound waves, the depth of penetration into the SMAS layer, analysis of the results of non-invasive lifting, comparison with complementary methods, and scientific care before and after treatment.
What is hypnotherapy and how does it work?
HIFU, which stands for High-Intensity Focused Ultrasound, is one of the greatest advances in dermatology in the field of non-invasive rejuvenation. This technology was developed with inspiration from diagnostic ultrasound waves, with the fundamental difference that the sound beams are converged here and concentrate concentrated thermal energy at specific depths in the underlying layers of the skin.
This controlled thermal injury immediately activates the biological phase of wound healing. Three basic steps occur in this pathway: the initial inflammatory phase, the cell proliferation phase, and the structural remodeling phase. The result of this chain is the secretion of fibroblast growth factors and neocollagenesis (synthesis of new elastic and type I and III collagens), which restores the elastic consistency and inhibits skin sagging.
Depth of penetration engineering and therapeutic cartridges
The unique advantage of HIFU over conventional lasers or RF is its ability to safely access underlying structures without damaging the epidermis. The layer that is cut and stretched by the surgeon in traditional facelifts (rhythmectomy) is called the superficial musculo-aponeurotic system ( SMAS ). HIFU is able to acoustically shrink this very layer.
| Cartridge / Penetration depth | Biological target layer | Clinical purpose and function | Common area in treatment |
|---|---|---|---|
| 1.5 mm | Upper dermis and lower epidermis | Improves skin texture, closes open pores, fine lines and crow's feet | Around the eyes, forehead, fine lines of the lips |
| 2.0 mm (micro) | Deep dermis and elastin network | Reduction of midline wrinkles and structural hydration | Wrinkles around the mouth, superficial folds on the neck |
| 3.0 mm | Deep dermis and superficial subcutaneous fat | Deep collagen formation, firming, reduction of loose tissue | Cheeks, jaw angle, laugh line, lower half of the face |
| 4.5 mm | Muscular aponeurotic layer (SMAS) | Anchorage lift, muscle support layer contraction, jaw shaping | Cheekbones, double chin, lower jaw edges, platysma of the neck |
In modern treatment protocols, the multi-depth layering technique is used; this means that first the muscle scaffold is stretched with a 4.5 mm cartridge, then the dermis volume is tightened with a 3.0 mm cartridge, and finally the surface texture and skin radiance are stabilized with a 1.5 mm cartridge.
Ideal candidates and target areas: face and neck
Accurately identifying the right candidate is half the clinical success in hypnotherapy. If the patient has unbalanced expectations or the degree of sagging skin tissue exceeds the capacity of a non-invasive response, the therapeutic outcome will not be satisfactory.
People aged 30 to 55
Patients who experience mild to moderate skin laxity and want to prevent structural aging without surgical recovery.
Sagging jawline and double chin
Those who have lost the clear angle of their jawline and have a slight accumulation of tissue and laxity under the chin.
Surgical lift maintenance
People who have previously undergone a facelift and are looking for an annual procedure to stabilize the muscle shape and maintain its durability.
Main clinical areas in face and neck contouring:
- Jawline and mandibular edges: Eliminate sagging jowls and restore the sharp jawline to the profile view.
- Double chin and under the chin: Tightening of soft connective tissue and collagen contraction in the muscles of the floor of the mouth to correct the profile.
- Neck platysma and scaly bands: Control horizontal lines called neck rings and gather excess neck tissue.
- Cheeks and Nasolabial Lines: Upward lift of the sagging malar tissue (Malar Fat Pad) which dramatically reduces the depth of the laugh line.
- Eyebrow and forehead lift: Open the eyes and reduce the heaviness of the upper eyelid by focusing on the arteries and temporal tissue.
Step-by-step steps of the process in the clinic
HIFU treatment does not require hospitalization, general anesthesia, or surgical incisions. The standard protocol for performing the procedure on the face and neck is set according to the following steps:
Clinical evaluation and facial mapping
The doctor marks the path of vital vessels and nerves (especially the marginal mandibular branch and the temporal facial nerve) on the skin with a pencil to ensure complete safety and to avoid shooting in prohibited areas.
Tissue preparation and ultrasound interface gel
The skin is disinfected and an even layer of ultrasonic coupling gel is applied to the site. This gel is a conductive medium to perfectly guide the waves without friction and prevent the loss of sound energy into the air.
Handpiece adjustment, beam angle and symmetrical shotting
Calibrated shots with regular linear compression and a predetermined count (on average between 500 and 900 shots depending on the size and condition of the face and neck) are released with gentle pressure perpendicular to the layers.
Cleansing and applying topical sedatives
The gel is removed, the skin is cooled and soothed with lotions rich in aloe vera and hydration complexes, and the patient is discharged without the need for any dressings.
Timeline of effectiveness and durability of results
One of the common ambiguities among clients is the exact time of seeing the lift. Since the basis of HIFU is the body's biological stimulation for tissue formation, the process of changes evolves over time and the immediate result is limited to the initial thermal contraction:
Immediately after treatment (10 to 20%)
Collagen protein contraction due to heat; skin feels tighter and cheeks appear slightly more prominent.
Month 1 to 3 (Collagen Peak)
Fibroblasts create new protein networks. The jawline becomes clearer and the angle between the neck and chin becomes more clearly visible.
Month 3 to 12 (Stability)
The skin's firm structure remains firm with enhanced firmness. The effects last for 12 to 18 months depending on lifestyle and skin care.
Possible side effects and clinical safety principles
Hypnotherapy is a clinically validated and safe procedure, but since high energy is released deep into the tissue, it is essential to master the vascular and neural anatomy of the face. It is essential to recognize the normal skin reactions and potential side effects:
Natural and transient reactions
Erythema and redness of the skin that resolves within 2 to 4 hours; mild subcutaneous edema and swelling for a few days; and a mild painful sensation on the jaw bone similar to a bruise after heavy exercise that resolves within two weeks.
Rare complications resulting from operator error
Temporary sensory nerve numbness or temporary crookedness of the corner of the lip due to discharge of the shot on the nerve trunk without proper depth measurement, blisters and linear burns due to the cartridge not fully adhering to the skin surface, and unwanted atrophy of cheek fat due to excessive energy.
- The presence of an open wound, very severe inflammatory acne, or active herpes infection at the treatment site.
- People with artificial heart pacemakers or electronic and metal implants in the head and face area (except standard dental root implants).
- Pregnant women or mothers in early lactation.
- Patients with advanced tissue repair disorders, severe systemic autoimmune diseases such as lupus, or a history of extensive keloid formation.
Critical care before and after treatment
The client's cooperation in adhering to the principles of care has a direct impact on maximum collagen synthesis and the prevention of unwanted skin reactions.
Pre-HIFU preparation protocol:
- Discontinue use of strong chemical peels, retinoids, tretinoin, and glycolic acid at least 3 to 5 days before HIFU.
- Avoid direct exposure to sunlight, solariums, or skin burns; HIFU should not be applied to inflamed or sunburned skin.
- On the day of the session, the face must be completely free of any foundation, cosmetics, beauty creams, and polluting particles.
Post-HIFU protection protocol:
- Avoid direct heat: Avoid saunas, hot tubs, hot baths, and strenuous aerobic exercise that causes heavy sweating for 48 hours. Heat should not promote controlled tissue inflammation.
- Photoprotective protection: Regular and generous use of a broad-spectrum physical sunscreen with SPF 50, with reapplication every 2 to 3 hours, is essential to prevent the development of post-inflammatory hyperpigmentation.
- Avoid heavy massage: Avoid deep massage, aggressive facials, or pressure manipulation of the jawline and cheeks for at least 10 days.
- Hydration and cellular nutrition: Drinking enough water and taking vitamin C supplements and oral collagen peptides can boost the precursors needed to accelerate the production of new collagen.
