What is a CO2 laser?

CO2 laser treatment uses the principle of absorbing moisture within the skin tissue and instantly burning it away.

It is one of the procedures used to treat flat warts that appear on areas such as the face and neck, by precisely shaving off the wart.

By using high-output energy, the procedure causes relatively little pain and minimal damage to the skin tissue.

It is used to treat various skin lesions such as moles, freckles, skin tags, milia, warts, and scars.

The precautions for the procedure are as follows.

After the procedure

  1. After the procedure, redness and a burning sensation may last for about 2 to 3 hours. Replace the regeneration tape applied to the treated area every 2 to 3 days, and it is recommended to keep it on for about 7 to 10 days.

  2. After the procedure, please take care of moisturizing to soothe the dried-out skin, and be careful to avoid sun exposure.

  3. After the procedure, the skin may become dry and skin troubles may occur, so adequate hydration and skin stabilization are necessary.

  4. Please take care with regenerative care so that the scabs that form after the procedure can fall off naturally.

  5. Light face washing is possible starting the day after the procedure, but be careful not to rub the areas with regeneration tape directly. Makeup is possible only after the scabs have fallen off, and when removing it, be careful not to pull the scabs off.

I’d like to know about other procedure information too!
