Quick answer: In Ultherapy 300 shots vs 600 shots, the number is how many lines of focused ultrasound are placed. 300 shots usually treats the lower face, jawline or a lighter full-face plan. 600 shots allows the full face and neck, or more lines at more depths, for a stronger lift. Your sagging, face size and goals decide the right count.
Key takeaways
- One Ultherapy "shot" is one line of focused ultrasound points.
- More shots mean more coverage or more layers treated.
- 300 shots often suits mild sagging or a focused area.
- 600 shots often suits the full face and neck or more visible sagging.
- Depth placement matters as much as the number of lines.
What does an Ultherapy shot mean?
Ultherapy is a micro-focused ultrasound treatment by Merz Aesthetics. Each time the transducer fires, it places a row of tiny heat points under the skin. This row is counted as one shot or one line. Different transducers reach 1.5 mm, 3.0 mm and 4.5 mm, and the deepest one reaches the SMAS, the layer that holds up the face. Live ultrasound imaging lets the doctor check the depth before each line.
What does a 300-shot plan usually cover?
A 300-shot plan often focuses on the areas that sag first: the jawline, jowls, lower cheeks and under the chin. It can also be used as a lighter full-face treatment for younger skin, or as a maintenance session for someone who had a larger treatment the year before. It suits people who want a clearer jawline without treating the whole face and neck.
What does a 600-shot plan usually cover?
A 600-shot plan gives the doctor enough lines to treat the full face, the area under the chin and often the neck. It also allows more layers in each area, for example lines at 4.5 mm for the SMAS and at 3.0 mm for the deep dermis. People with visible jowls, a softer neckline or a larger face often choose this plan for a more complete lift.
How do 300 and 600 shots compare?
- Coverage: 300 shots a focused area or light full face; 600 shots full face and neck.
- Layers: 300 fewer passes; 600 more lines at more depths.
- Strength of lift: 300 lighter; 600 usually more noticeable.
- Treatment time: 300 about 30 to 45 minutes; 600 about 60 to 90 minutes.
- Downtime: similar, usually a few days of mild tenderness.
Which plan suits mild sagging?
If your jawline is just starting to soften and the skin is still fairly firm, 300 shots is often a good first step. Placing the lines where sagging starts can give a natural lift. Many people in their 30s and early 40s use a focused plan once a year to slow down changes.
Which plan suits more visible sagging?
If you have clear jowls, loose skin under the chin or lines on the neck, 600 shots is often the better choice. The extra lines allow the doctor to lift the support layer and tighten the skin above it across a wider area. For very loose skin, combining Ultherapy with Thermage or a thread lift may help more than adding lines.
Do more shots always mean better results?
No. The quality of the plan matters more than the number. Lines must be placed at the right depth for each area, avoiding thin skin over bone and areas near nerves. A carefully mapped 300-shot plan can look better than a rushed 600-shot one. Ask your doctor how the lines will be divided between areas and depths.
Is it safe?
Ultherapy is safe when performed by trained doctors with a genuine device and transducers. Possible effects include temporary redness, swelling, tenderness, small bruises or tingling. Rare risks include small burns or temporary numbness. Genuine systems record the number of lines used, so you can ask to see it.
How to choose your shot count
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Ultherapy is one of the most requested lifting treatments. When you compare plans, ask which areas are included, which depths are used, whether the device is genuine and who performs the treatment.
Frequently asked questions
Is 300 shots enough for the full face?
For mild sagging it can be, but many full-face plans with the neck use more lines.
Does 600 shots hurt more?
Each line feels the same, but a longer session means more lines. Numbing cream helps.
How long do results last?
Results build over two to three months and usually last about a year.
Can I combine it with Thermage?
Yes. Ultherapy lifts the deep layer and Thermage tightens the skin above.
