DISCLAIMER: I am not using this soap for skin lightening. This is only being used to help get rid of hyperpigmentation.

Kojie San  Acid Soap has all-natural kojic acid formula that can help lighten dark spots that may be due to skin pigmentations. Kojic Acid was discovered in Japan and is used in the manufacture of Japanese rice wine.


  1. Wet face with water
  2. Take soap and rub between hands
  3. Apply product to face and work in circular motion for 45 seconds
  4. Rinse thoroughly


Please follow the directions on this package. This is a very strong soap (acid) and must be used with precaution and a moisturizer with at least SPF 30 (to prevent further discoloration).

Before using this product, test it on a small part of your skin to be sure you do not have an allergic reaction. I did the 24 hour skin patch test on my arm before applying to my face.

Some people have reported that this soap has made their skin red and burn really bad. This is why I stress to start off using the product only once a day for 15 seconds and then wash it off your face. I started off like this and so far I have not had any reactions after one month of use.


  • A light, pleasant, orange peel scent
  • My skin felt very smooth to touch after each use.
  • Breakouts got fewer and further in between.


  • This product is very drying to the skin, so after each use I use Aloe Vera and follow that up with Aveeno Simply Radiant Moisturizer SPF 30.


I use this product once a day, at night. I wash my face with this soap and leave it on for 45 seconds and rinse thoroughly.

I have light and really dark areas of hyperpigmentation on my face. After a one month use, I have noticed that the lighter hyperpigmentation spots have almost left, however I still have the darker spots on my face, but they seem to be a medium, instead of a really dark shade.

Many people have commented that all their hyperpigmentation has been erased after two weeks, but I’m not sure how true that is. I will continue to use this soap for another 2 months and make another update with pictures.

Please stay tuned !
