Dark circles under the eyes, especially those caused by fat and loss of elasticity, may see some effect from "high-frequency electric shock," but it may not be as dramatic as expected.

What is high-frequency electric shock?

  • Commonly referred to as RF (Radio Frequency) high-frequency devices.

  • It works by applying heat to the dermis to stimulate collagen and increase elasticity.

  • Types: Many brands such as Thermage, Inmode, Tenage, etc.

Expected Effects When Applied to Under-Eye Fat

Advantages:

  • The skin appears slightly tighter, and the sagging under-eye area is slightly lifted

  • Swelling decreases, and the skin may become a bit brighter

  • Less burden compared to surgery (non-invasive)

Limitations:

  • If there is a lot of actual fat or protrusion under the eyes, the effect is minimal

  • One treatment shows minimal effect, and multiple sessions are needed for slight differences

  • The skin is very thin in this area, so excessive high-frequency may cause irritation

Is it reliable?

If reliability means effectiveness:
→ It can partially help with dark circles caused by small amounts of fat and loss of elasticity
→ However, if the fat is prominent or there are structural issues causing shadows, fillers, fat repositioning, or surgical treatments are more certain.

What to Check Before Treatment

  • Ensure the clinic performing the treatment has medical licensing

  • Check if the device used is a certified medical device (FDA, KFDA, etc.)

  • During consultation, ensure they accurately diagnose the type of fat under the eyes

It can be reliable, but the limitations are clear, and it should be considered a 'supplementary improvement measure.'

If the under-eye area is prominent or has deep shadows, other approaches may be necessary.
