Ultracel Q

Ultracel Q is a high-intensity focused ultrasound (HIFU) platform made by Jeisys Medical, a Korean aesthetic device manufacturer. It sits in the non-surgical lifting and tightening category, and at Kaiteki it is one of the devices used within the HIFU treatment. Rather than working on the skin surface, HIFU passes focused ultrasound energy through the surface and concentrates it at a chosen depth below it, so the layer being treated is deeper than the layer the handpiece touches.

What distinguishes the platform for someone comparing HIFU devices is that it is cartridge-based: the doctor swaps cartridges to change the focal depth and the shape of the heat that is delivered, instead of working at one fixed setting. Whether HIFU is appropriate for you at all, and if so, which depths and how many passes, depends on your degree of laxity, tissue thickness and medical history, which a doctor assesses at an in-person consultation.

Each cartridge focuses ultrasound to a small point at a set depth, creating controlled heating there while the skin surface is largely spared. Jeisys also offers a linear cartridge series it calls LinearFirm, which spreads the focus along a line rather than a single dot, giving a longer continuous heat zone in one pulse. Jeisys states that irradiation time drops from roughly 1.5 seconds per pulse with a dot cartridge to about 0.7 seconds with a linear cartridge, and describes the shorter exposure as more comfortable.

Jeisys also describes the platform as operating at a moderated focal temperature (quoted in its clinician material as around 60–65°C, below the range at which collagen is fully broken down) with the intention of prompting collagen renewal through partial thermal denaturation rather than complete destruction. The cartridges have a compact contact tip, which the manufacturer says helps reach awkward contours such as the jawline and under the chin. Depth, energy, cartridge choice and the number of lines delivered are all selected by the treating doctor. Any change develops gradually over weeks and varies between individuals.

Jeisys supplies cartridges of differing focal depths so that the dermis, the deeper SMAS layer or the fat layer can be targeted according to the plan. The SMAS (superficial muscular aponeurotic system) is the deeper support layer of the face: the same layer a surgical facelift addresses, though focused ultrasound reaches it without incisions.

Which depths are used, and how many lines at each, depends on your degree of laxity and your tissue thickness, which a doctor assesses in person.

No. It is a tightening-type treatment rather than a substitute for surgery: it does not cut, lift or remove skin, and the degree of change is not comparable to surgery. Significant, heavy sagging is often better discussed as a surgical question, and your doctor will say so honestly if that is the case.

Ultracel Q is commonly considered for early to moderate laxity in the lower face and neck, and for definition along the jaw. It is not suitable for everyone. Concerns it is typically considered for include:

Because focused ultrasound is absorbed by tissue rather than by pigment, HIFU is generally used across a wide range of skin tones, including deeper Asian skin, without the pigment-related considerations that apply to some lasers. It tends to be aimed at people with early to moderate laxity who want a non-surgical option.

Ultracel Q may not be suitable during pregnancy or breastfeeding, over active skin infection or inflammation in the treatment area, or where there are implants, metallic devices, cardiac devices or dermal fillers in the intended path. Certain medications, keloid tendency and some medical conditions also need to be considered. Please share your full medical history, medication list and any previous aesthetic treatments at consultation so the doctor can advise safely.

A visit starts with a doctor consultation, an assessment of where your laxity actually sits, and a discussion of whether HIFU is the right tool for it. If it is appropriate, the skin is cleansed, treatment areas are marked, and ultrasound coupling gel is applied. Topical numbing may be used depending on the area and your comfort. The doctor then delivers the shots line by line with the selected cartridges; most people describe brief warmth, prickling or a deep tapping sensation that comes and goes with each pulse rather than continuous pain.

A full face and neck session commonly takes somewhere in the region of 45 to 90 minutes including preparation, depending on the areas covered. HIFU is often planned as a single session with review some months later, or as a small number of sessions spaced out over time, with occasional maintenance afterwards. Your doctor will set out what is realistic for your face at consultation.

Downtime is usually minimal, and most people return to normal activities the same day. Mild redness, slight swelling, tenderness to touch or a temporary feeling of firmness in the treated area can occur and generally settle over a few days.

Gentle skincare and daily sun protection are advised afterwards. Your doctor may ask you to avoid vigorous heat exposure such as saunas for a short period, and will give aftercare guidance specific to your treatment plan.

As with any medical procedure, HIFU with Ultracel Q carries risks, which are explained during consultation. Temporary effects can include redness, swelling, tenderness, small areas of bruising, or transient numbness or tingling in the treated area; less commonly, welts or temporary nerve-related effects such as localised muscle weakness have been reported with focused-ultrasound treatments. Serious effects are uncommon when the treatment is appropriately selected, correctly mapped and performed by a trained doctor.
