Focused ultrasound facial rejuvenation (HIFU)

The EunSung Microson Pen offers the latest HIFU technology (High-Intensity Focused Ultrasound), enabling facial rejuvenation, skin tightening, and a non-surgical facelift. This treatment is designed for those who want a more youthful appearance without undergoing plastic surgery.

The device operates with extreme precision, delivering focused ultrasound energy to various layers of the skin, all the way down to the SMAS layer (the subcutaneous, muscle-like layer that gives the face its shape and firmness), making the effects both noticeable and comprehensive. The pen-style device comes with interchangeable treatment heads, allowing even hard-to-reach areas—such as around the eyes and mouth—to be easily treated. This means every part of the face can be tightened accurately and gently.

The treatment is fully customizable: the practitioner can adjust the number of shots for each area of the face and control the speed of the procedure, ensuring that every client receives a treatment tailored to their skin and needs. During the procedure, small, controlled thermal injury points (60–65 ℃) are created in the skin, producing immediate tightening often referred to as “shrinking” or tissue contraction. Afterward, the skin begins to produce new collagen for regeneration.

As a result, the skin gradually tightens naturally and regains its youthful elasticity. While the results are not immediate, they are long-lasting and visually impressive. The tightening and lifting effects develop over 2–3 months and can last up to a year, ensuring a youthful appearance in the long term.
