Can I Use My Curling Iron in South Korea?
You'll need a converter and an adapter.
Two things differ here: the voltage and the plug shape. You need both a voltage converter (transformer) rated above your device's wattage and a plug adapter to fit local sockets. Do not plug in with only a plug adapter — an adapter does not change voltage, and the wrong voltage can damage your device or cause a fire.
Based on a typical single-voltage US model — confirm your device's label to be sure.
The short answer
Curling irons and straighteners are heating elements: on the wrong voltage they overheat instantly. A US 120V single-voltage iron on 230V can scorch hair, melt, or fail. Lower wattage than a hair dryer, but the same rule applies — confirm "100–240V" on the barrel, or carry a dual-voltage model. Frequency (50/60Hz) does not affect heating.
South Korea runs 220V at 60Hz. South Korea runs 220V at 60Hz with European-style Type C/F sockets, which often surprises US visitors. US single-voltage devices need a converter.

FAQ
Will a travel adapter let me use my curling iron in South Korea?
No. A travel adapter only changes the plug shape — it does not change voltage. Your curling iron would still receive 220V.
Do I need a voltage converter for a curling iron in South Korea?
Yes — your device runs on a single voltage that doesn't match South Korea's 220V.
What plug type does South Korea use?
South Korea uses Type C, F sockets at 220V / 60Hz.
