How Painful Is Sofwave, Really? Who Can Get By with Numbing Cream — and Who May Need More
Those with prominent cheekbones or a defined jawline, and those with thinner skin, are typically advised to consider additional anesthesia. Here's a guide to help you find the right numbing approach for your case.
One of the first questions people ask when researching Sofwave is: "How painful is it, exactly?" Pain perception varies from person to person — some patients breeze through the entire procedure with just numbing cream, while others find that one or two areas feel more intense and benefit from additional anesthesia right from the start.

The short answer: Sofwave feels like a series of brief, stinging pulses of heat delivered in quick succession. Most patients manage comfortably with topical numbing cream alone, but areas close to the bone — like the cheekbones or jawline — can feel noticeably sharper. Knowing in advance which category you're likely to fall into can help reduce anxiety during the procedure.

Sofwave delivers short ultrasound pulses* to the mid-dermis (approximately 1.5mm depth) to stimulate Collagen production. The sensation is best described as brief, pinpoint flickers of heat passing through the skin one spot at a time. Compared to other HIFU-based procedures that produce a deep, pressure-like ache, Sofwave feels more like a rapid surface warming — lighter and quicker in nature.
*Ultrasound: A technology that focuses inaudible vibrations beneath the skin and converts them into thermal stimulation. It is commonly used in non-invasive tightening procedures such as Sofwave.
Understanding the depth at which Sofwave operates in a cross-sectional view makes it easier to understand why the sensation has this particular quality.
A clinical study analyzing SUPERB (Synchronous Ultrasound Parallel Beam) skin tightening reports that energy concentrated in the mid-dermis leads to measurable increases in Collagen and elastic fibers in that layer. A contact cooling system also operates simultaneously during the procedure, which helps moderate the Heat sensation to a meaningful degree.
Who Typically Does Well with Numbing Cream Alone
If most of the following apply to you, there's a good chance you'll complete the procedure comfortably with topical numbing cream only.
- You generally tolerate injection-related Pain well
- Your treatment area involves relatively little of the bony prominences — cheekbones, jawline, or forehead
- Your skin tends to be on the thicker side
- You've minimized caffeine intake in the hours before your appointment
Thicker skin helps disperse the Heat sensation more gradually as it reaches the mid-dermis. A treatment zone with less bony prominence means less vibration conducted through the bone, which translates to a milder overall sensation. Reducing caffeine one to two hours before the procedure can also lower neural sensitivity, making Pain signals feel less sharp.
The American Society for Dermatologic Surgery notes that non-invasive tightening procedures using ultrasound and Radiofrequency (RF) are generally well-tolerated, though local anesthesia may be required depending on the device. Sofwave is most commonly performed with surface numbing cream as the standard approach.
When Additional Anesthesia Is Recommended
Additional anesthesia is typically advised before the procedure begins if any of the following apply to you.
- More than half of your treatment area involves bony areas such as the cheekbones, jawline, or forehead
- Your skin is on the thinner side, including around the eyes or temples
- You've found that dental anesthesia tends not to work as well for you
- You've had a previous HIFU procedure where you needed to stop partway through
When ultrasound energy reaches areas close to the periosteum — such as the cheekbone or jawline — the vibration conducts through the bone and registers more intensely. Even though the sensation is characterized by brief, surface-warming pulses, thinner skin allows the Heat from the mid-dermis to transmit closer to the surface, making the same procedure feel noticeably different. For patients in this category, we may extend the topical numbing cream application time starting 30 minutes before the procedure, or provide supplemental nerve-blocking support when indicated.
The chart below offers a general sense of how Pain perception tends to differ by area. Keep in mind that these are average tendencies — the same area can feel quite different from one person to the next.
At Beautystone Clinic in Hongdae, We Tailor the Sofwave Approach to Each Patient
Even though every patient receives the same Sofwave procedure, the way we structure the session at Beautystone Clinic in Hongdae is adjusted based on your skin thickness, Pain tolerance, and the specific areas being treated. Numbing cream application time is calibrated to your skin condition, and for patients with a higher proportion of cheekbone and jawline in their treatment zone, we build in brief rest intervals mid-session — so that we move to the next line before the numbing effect begins to wear off.
The American Academy of Dermatology recommends that patients ask their provider about Pain, Downtime, and expected outcomes before any cosmetic procedure — noting that doing so is a key step in minimizing risk. Our clinic is within walking distance of Hapjeong Station, making it easy to stop by for a brief pre-procedure consultation to discuss how the procedure may feel for you specifically before committing. The difference lies not just in the result, but in identifying the right anesthesia approach for your individual case first.
Small Details That Help Reduce Discomfort During the Procedure
Even with the same anesthesia, there are small details that can meaningfully lower Pain perception during the procedure.
- Reduce caffeine intake one to two hours before your appointment
- Have a light meal beforehand rather than arriving on an empty stomach
- Breathe slowly and steadily throughout — shallow, rapid breathing tends to amplify Pain
- Mentally prepare yourself as the device approaches the cheekbone and jawline areas
Topical numbing cream typically reaches peak effectiveness 20 to 30 minutes after application. For this reason, at Beautystone Clinic in Hongdae, we schedule the procedure start time to align with the optimal numbing window. If a particular line feels difficult to tolerate mid-session, we pause at that point and offer additional anesthesia or a rest break — so please signal to your provider rather than pushing through. This article is intended as general information; the right Pain management and anesthesia approach for your specific case should always be determined in consultation with your medical provider before the procedure.
Frequently Asked Questions
Q. Can I ask to stop if it becomes too uncomfortable mid-procedure?
A. Yes, absolutely. If you raise your hand or signal to your provider, we'll pause the current line and offer additional anesthesia or a rest period. Stopping when needed is actually safer for your results than trying to push through.
Q. Will using more numbing cream reduce the effectiveness of the procedure?
A. Topical numbing cream does not directly affect the outcome of Sofwave. The mid-dermis depth at which Sofwave operates is deeper than the level topical anesthesia reaches. That said, additional application may extend your overall appointment time, so it's a good idea to allow some flexibility in your schedule.
Q. How long does the Pain last after the procedure?
A. The most noticeable sensation immediately after is a warm, slightly flushed feeling in the face, which typically subsides within a few hours. Some patients experience mild achiness the following day, but this generally does not interfere with daily activities. Individual experiences vary.
Q. How does it compare to other procedures known for being less painful?
A. Among HIFU-based procedures, Sofwave's shorter pulse duration and simultaneous contact cooling make it feel lighter than the deep, pressure-like sensation associated with other devices. That said, Pain perception is highly individual, and direct comparisons can be misleading. We recommend discussing Pain expectations, Downtime, and anticipated outcomes with your provider before making any decision.
