San Fu Scarring and Blisters

Everyone reacts differently to the San Fu application and it can be hard to gauge exactly what your body will do until you try it. Everything from melanin level, to genetics, to age, to sex, to medications, to current health status, to comorbidities will impact whether or not you will scar and what that scar will look like. Common reactions include: 

  • A sensation of heat, redness, and itching at the site of application

  • Slight fever

  • Sore throat or flu like symptoms lasting approximately 24 hours

  • Blisters; some people will have blisters that can take up to 72 hours to appear

  • Red dots that are about the same color as a sun burn when they first remove the applications

The color, size, appearance, and location of the blisters will vary. Sometimes only a few of the points will blister, while other points that were applied at the same time will appear seemingly unaffected. The skin may also start to darken and create a thin scab like covering which will eventually fall off to expose healed pink "baby" skin underneath.


Remove the San Fu applications after 6 hours or if they start to become overly hot and itchy - whichever comes first.

  • Wash the skin with with soap and water followed by gently patting the skin dry with a clean cloth or towel.

  • If blisters appear, treat them as you would with any normal blister.

    • Keep the area clean and once the fluid comes out, do not remove the top layer of skin.

    • Keep the wound clean at all times and cover with a band aid during the day to keep it protected.

    • Feel free to use Neosporin or a topical cream that works well for you. Do not use medicinals known for taking the heat out of a burn because you want to be sure to preserve the Yang herbal remedies that were delivered through the dermis into the muscle layer. However, you do want to insure that the blister does not become infected as it heals.

  • As with all wounds, depending on your skin you may scar. Wheat germ oil, tamanu oil, or Mederma scar gel all work wonders do lighten the color of scars.
