For years, the only way to address moderate to severe skin laxity on the face—such as jowls, double chins, and sagging brows—was to undergo surgical rhytidectomy (a traditional facelift). However, advanced technology has introduced a highly effective, non-invasive alternative: High-Intensity Focused Ultrasound (HIFU), often referred to in premium clinics as 12D HIFU or BelluTherm.
In this guide, we break down the science of HIFU, how it works, what to expect during a treatment, and why it has become the go-to facelift alternative in Manila.
The Science: How HIFU Lifts from Within
Unlike lasers and radiofrequency (RF) which heat the skin from the outside in, HIFU bypasses the surface of the skin entirely. It delivers precise, micro-focused ultrasound energy to deep structural layers, specifically targeting:
1. The Dermis: Stimulating immediate contraction and long-term production of collagen and elastin fibers. 2. The SMAS Layer (Superficial Musculoaponeurotic System): The deep muscle-anchoring layer that plastic surgeons pull and tighten during a surgical facelift.
By heating these deep tissues to approximately 60–70°C, HIFU creates micro-coagulation zones. This triggers the body’s natural healing response, resulting in the rapid production of fresh, tight collagen over the next 2 to 6 months.
Key Benefits of HIFU Facelift
- **Non-Invasive**: No cuts, no needles, no incisions, and no anesthesia required.
- **Single Session Results**: Many patients notice an immediate 10–20% lift post-treatment, with full results locking in after 3 months as new collagen matures.
- **No Downtime**: You can immediately apply makeup and return to your daily office routine or social activities.
- **Highly Targeted**: Excellent for redefining the jawline, raising eyebrows, reducing nasolabial folds, and tightening double chins.
What Happens During a Session?
A standard HIFU session at Bellus Aesthetics takes between 45 to 90 minutes, depending on the size of the treatment area.
1. Cleansing: The skin is thoroughly cleansed to remove makeup and oils. 2. Marking: The doctor or aesthetician marks the target grids on the face, avoiding critical nerve pathways. 3. Gel Application: A conductive ultrasound gel is applied to ensure smooth energy delivery. 4. Energy Pulses: The handpiece is pressed against the skin, delivering ultrasound pulses. Patients typically feel a deep, warm tingling sensation or mild aching along the jawline, indicating the energy is reaching the SMAS muscle layer.
Who is the Ideal Candidate?
HIFU is highly recommended for individuals aged 30 and above experiencing mild to moderate skin laxity. It is also an excellent preventative treatment for younger patients looking to maintain high skin density and prevent early jowling.
For severe skin sagging or deep fat pads, our doctors may recommend combining HIFU with dermal fillers or threat lifts for a customized facial rejuvenation plan.
