Are 300 Shots of Ultherapy PRIME Enough? Q&A on the Right Shot Count and How Long Results Last

Ultherapy PRIME, the next-generation version of Ultherapy — the name synonymous with skin lifting — has been released, and many of you have been asking us about the treatment. One of the questions we hear most before treatment is "How many shots do I need?" or "Will just 300 shots work?".

Today we walk you through the key questions you have been asking — who 300 shots of Ultherapy PRIME are right for, the recommended number of shots by area, and how long results last — in a Q&A format.

Q1. Are 300 shots of Ultherapy PRIME really enough?

A. For focused care of specific areas, or for early lifting and refining the facial contour in your 20s and 30s, 300 shots can give sufficient results.

Ultherapy PRIME's real-time ultrasound imaging (DeepSEE™) is even more refined, accurately visualizing the thickness of the skin layers and the position of the SMAS (fascia) layer as energy is targeted. So even with fewer shots, precise targeting makes efficient lifting possible.

Who 300 shots are recommended for

• Focused improvement of a double chin and jowls: When you want focused treatment on just the jowl and double-chin line rather than the whole face

• Late 20s to early 30s: An early lifting stage, when sagging is not severe and you want to tidy up fine lines and contours

• Regular lifting maintenance: When you have previously had 600 shots or more and come back 6 months to 1 year later for a top-up treatment to maintain results

However, if the whole face (jowls + sagging cheeks + double chin + nasolabial folds) is treated at once, or you are in your 40s or older with a visible loss of skin elasticity, 300 shots alone spread the energy too thin, and you may be less satisfied with the result.

Q2. What is the right number of Ultherapy PRIME shots for each area?

The recommended number of shots depends on the size of the treatment area, skin thickness and fat distribution. It varies from person to person, but the general guide is as follows.

Q3. How long do Ultherapy PRIME results last, and how often should it be repeated?

A. On average, the results of one treatment last about 1 year to 1 year and 6 months.

Ultherapy PRIME works by delivering high-intensity focused ultrasound (HIFU) energy into the skin to create thermal coagulation points, which stimulate collagen regeneration over several months.

• When results appear: You may feel slight tightening right after treatment, and contour improvement and lifting reach their peak 2–3 months after treatment, when collagen production is in full swing.

• How long it lasts: About 1 year, and up to 1 year and 6 months.

• Recommended interval: To slow skin aging and keep skin firm over time, we recommend a regular treatment once a year. (For 300-shot maintenance, every 8–10 months.)

Q4. How is Ultherapy PRIME different from the original Ultherapy?

1. Sharper real-time ultrasound (DeepSEE™): Screen resolution is much improved over the previous device, so the practitioner can check the target layers (SMAS, fat and dermis) in detail in real time and deliver energy safely.

2. Faster treatment and better tip contact: Faster energy delivery shortens treatment time, and closer contact between the tip and the skin minimizes the risk of side effects (such as cheek hollowing or cheek bulging).

3. More comfortable in terms of pain: More precise real-time monitoring reduces unnecessary impact on soft tissue, further easing the pain patients feel and the burden of swelling (downtime).

Q5. Why can Ultherapy cause cheek hollowing or bulging? Is PRIME safe?

The side effect people worry about most with Ultherapy is "cheek hollowing" (sunken side cheeks) or a "hollowed face."

• Cause: It happens when a tip that is too deep (4.5mm) is used, or too much energy is delivered, on areas with thin skin or little fat, so the fat layer shrinks.

• How Ultherapy PRIME helps prevent it: Because the PRIME device offers higher ultrasound resolution than before, the treatment is performed while scanning the position of the fat and SMAS layers in real time. Energy can go deep into the double chin and jowls, where fat needs to be reduced, while areas prone to hollowing, such as the side cheeks, are switched to shallow tips (1.5mm–3.0mm) for a custom-designed treatment.

Q6. Which treatments work well with Ultherapy PRIME? (e.g., Ultherapy + Thermage)

Skin aging comes from both sagging of the SMAS layer and loss of collagen in the dermis. That is why combination treatments with a synergy effect have become more popular than using a single device.

1. Ultherapy PRIME + Thermage (the Ultherapy + Thermage combination)

   • Ultherapy PRIME (HIFU): Lifts the deep SMAS fascia layer for contour and jawline lifting

   • Thermage FLX (radiofrequency): Delivers heat energy to the shallow dermis for fewer fine lines, subtle firmness and tighter pores

   • Effect: Improving the surface and the deeper layers at the same time sharply increases how long results last and how satisfied patients are, compared with a single treatment.

2. Ultherapy PRIME + Skin Botox / Rejuran

   • Maximizes lifting together with smoother fine lines and better skin hydration and barrier.

Q7. Precautions & aftercare tips to get the most from your treatment

With Ultherapy PRIME, what matters most is the collagen regeneration that takes place over the 2–3 months after treatment. Following these precautions can help your lift last longer.

• Keep the warmth (1 week after treatment): This is when thermal coagulation points form in the skin and collagen regenerates, so avoid washing your face with cold water or using ice packs, and wash with lukewarm water instead.

• Avoid alcohol and saunas: For about 1 week after treatment, it is best to avoid hot saunas, jjimjilbang (Korean bathhouses) and heavy drinking.

• Moisturize and protect from UV: To support collagen production, apply plenty of moisturizer, and always use sunscreen thoroughly when you go out.

Q8. Why checking for genuine Ultherapy PRIME tips matters

To be sure of the safety and results of Ultherapy, always check that genuine Merz tips are used. Reused (refilled) tips can cause side effects such as burns, cheek hollowing or poor results.

1. Check the genuine-product sticker: Right after treatment, receive the genuine-product verification sticker (QR code) attached to the box, together with the certificate of authenticity.

2. Register in the verification app: Register the QR code in Ulthera's official genuine-product verification app ('처음부터 울쎄라') to confirm that the product is genuine and earn points for your genuine shots.

📌 Summary: how to choose the right Ultherapy PRIME for you

• Spot improvement of the double chin or jawline or early anti-aging is your goal ➡️ Start with 300 shots

• Lifting overall facial sagging and the cheeks, and complete contouring is your goal ➡️ Full face with 600 shots or more recommended

With Ultherapy PRIME, more shots are not automatically better; a custom design matched to your skin thickness and precise energy delivery matter most. Before treatment, consult experienced medical staff, with real-time ultrasound monitoring, about the right number of shots for you.
