Doublo Gold vs Shurink: A Complete Guide to the Differences and How to Choose

Doublo Gold and Shurink: Both Are 'HIFU Lifting' Devices

Doublo Gold and Shurink are both lifting devices that use High Intensity Focused Ultrasound (HIFU) to deliver thermal energy to the dermal layer and the muscle fascia layer (SMAS) of the skin. When ultrasound energy converges at a specific point at a certain depth, it forms a thermal coagulation point, and this stimulation is intended to induce collagen production and tissue remodeling, aiming to help improve skin elasticity.

Both devices are classified as non-invasive procedures that don't involve cutting, and they tend to have relatively short procedure times with quick return to daily activities. However, the two devices have detailed differences in their country-specific certification pathways, ultrasound generation methods, cartridge types, and depth options, and understanding these differences can be helpful when choosing between them.

Differences in How the Two Devices Work

Doublo Gold is a domestically developed HIFU device that uses linear ultrasound delivery along with a rotating cartridge to stimulate a wide area relatively evenly. It is known to have a cartridge lineup that allows the treatment depth to be adjusted across a range from shallow layers beneath the epidermis to the fascia layer, depending on the area and purpose.

Shurink is also a domestically developed HIFU device, characterized by using micro and macro tips to divide the treatment depth from the shallow dermis to the fascia layer. It is often used with a combination of different-depth cartridges depending on the area.

Both devices cover a range roughly from the dermal layer (shallower skin layer) to the SMAS fascia layer (deeper layer), but the exact treatment depth, energy intensity, and number of shots vary depending on the device settings and the practitioner's judgment. Which device is more suitable for a particular skin concern depends on individual skin thickness, degree of sagging, and facial area, so it is difficult to determine superiority uniformly.

Perceived Effects, Progress, and Downtime

The collagen remodeling response after HIFU treatment tends to progress gradually over weeks to months rather than appearing immediately. It is therefore known that changes in skin elasticity are often noticed over time rather than right after the procedure, and this perceived degree and duration can vary depending on individual skin condition, age, and lifestyle habits.

In terms of downtime, both devices are known to have relatively short downtime, but temporary redness, warmth, mild swelling, or a feeling of tightness may occur at the treatment site. These symptoms usually subside within a few hours to a day or two after the procedure, but the degree and duration may vary depending on individual skin sensitivity.

Rarely, temporary bruising or sensory changes may accompany the procedure, and these also generally resolve naturally over time. It is important to fully inform the specialist of your skin condition and medical history before the procedure and to consult about the treatment method, energy settings, and expected course.

The Recovery Period After the Procedure: How Home Care Makes a Difference

Immediately after HIFU treatment, the skin barrier may become temporarily sensitive due to the thermal energy delivered. During this period, following basic skin protection guidelines—such as sun protection, avoiding exposure to high-temperature environments, and refraining from vigorous massage or exfoliation—can help support recovery.

In addition, combining soothing and moisturizing care after the procedure can help keep the skin more comfortable as temporary redness or sensitivity subsides. However, it should be noted that this does not replace or guarantee the effects of the procedure itself, but rather serves as supplementary care for managing skin condition during the recovery period.

Recovery After the Procedure Depends on Home Care

Immediately after the procedure, the skin is more sensitive than usual due to thermal stimulation, so using low-irritation products focused on soothing and barrier care during this period can be helpful. The Abiogen (AbyzuU) cream is designed as a 2-step home care system for after the procedure: STEP 1, Ultra Cera-Rich, is intended for soothing and barrier care for skin that has become sensitive right after the procedure, while STEP 2, Hydro Re-Boosting, is designed for deep moisturizing care during the subsequent recovery period. This home care cannot be said to guarantee the procedure's effects or speed up recovery, and should be considered simply as one reference method for managing individual skin condition.
