As I aged, the first place I noticed changes was my skin. When elasticity drops and wrinkles begin to form, I really feel the onset of aging. Once wrinkles have formed or elasticity has decreased, it can be difficult to reverse with self-care alone, so I decided to try ultrasound lifting, which does not require an incision.

No Incision Required

This method does not involve cutting the skin, so I was able to approach it with a light heart. The short procedure time and not having to take a long recovery period also reduced the burden, allowing me to return to daily life immediately.

  • No incision
  • Relatively short procedure time
  • Quick return to daily life

The biggest difference from self-care was that it accessed not just the surface, but the deep layers of the skin.

Tightening Created by Thermal Coagulation Points

When high-intensity focused ultrasound energy is delivered to the skin, it forms thermal coagulation points, which can lead to tightening. In this process, the stretched skin regained elasticity. While cosmetics and beauty devices only deal with the surface and thus have limitations, ultrasound is different in that it delivers energy to deep layers.

To the Dermis, Fascia, and SMAS Layers

HIFU energy is said to deliver energy to the dermis, fascia, and SMAS layers without damaging the surface. By forming thermal coagulation points in the skin tissue, it helps with tightening and induces collagen regeneration in the deep layers, which can also lead to natural volume. It was impressive that it could access deep layers without harming the surface.

The Process of Awakening Collagen

When appropriate energy is delivered, it awakens collagen deep within the skin, which helped to restore lost elasticity. However, since skin condition and areas of concern differ from person to person, a customized plan was necessary to achieve good results. Thanks to receiving treatment at a place that provided monitoring during the procedure and aftercare, I was able to complete it relatively stably.

Customized Adjustment with Modes and Cartridges

This method has been upgraded through generations, now featuring two modes and seven cartridge configurations. It allows for delicate adjustments of cartridges as needed, enabling personalized procedures. The key was that even with the same ultrasound lifting, the choice of cartridge varied depending on the depth and area being treated.

If you're wondering if ultrasound lifting is right for your elasticity concerns, please check via chat consultation. You can also compare it with Thermage FLX or Sofwave lifting, which also target deep layers.
