Where does Kojic Acid Come from?

mushrooms are the primary source of kojic acid

Did you know kojic acid comes from mushrooms?

Kojic acid was initially extracted from some mushroom species in Japan (around 1989). Nowadays scientists and manufacturers of beauty products mainly get it from soy, rice, as well as the Japanese Sake rice wine (or better said its leftovers after the fermenting process is complete). However, the primary source of kojic acid remains, who else, mushrooms and fungi in general.

How Does Kojic Acid work for Skin Lightening?

To put it differently; “What does kojic acid do to your skin to make it lighter?”
According to scientists, kojic acid works by preventing the production of tyrosinase, the enzyme that triggers melanin production.

For the science-savvy, we should mention that kojic acid blocks the catecholase function that is significant for the melanin production.
For those who just want the meat, however, it should suffice to say this; “Limited tyrosinase production leads to less melanin.”

And less melanin consequently leads to less dark spots and less pigmentation, as melanin is responsible for the color of our skin! Voila! So, let’s find out how you can use kojic acid to whiten your skin.

Kojic acid soap is a very potent skin whitening soap that contains kojic acid as well as one of the most popular skin whitening treatments. Let’s see why!

  • Daily use of kojic acid soap can help you whiten your skin and get rid of age spots, brown spots, acne scars and other hyperpigmentation problems.
  • Kojic acid is a much safer alternative to all those dangerous skin lightening products that contain harsh chemicals like hydroquinone
  • You can use kojic acid soap to exfoliate the upper layer of your skin. This way you can remove dead skin cells that make it look dark.
  • Skin whitening using kojic acid soap provides you with a natural-looking skin complexion. In other words, your skin color will look smoother and not as if it was “bleached.” This means that your skin tone will look even, instead of having evidently whitened blocks.
  • Kojic acid soap can also be used to fight hyperpigmentation in different areas of the body apart from your face. These include dark underarms, knees, the inner thigh area, and, of course, buttocks. That’s why we highly recommend using kojic acid in our how to get rid of dark spots from your buttocks easily guide.

How to use Kojic Acid Soap to Whiten your Body and Face. Instructions

When it comes to applying Kojic Acid Soap to your body, everything is a pretty straightforward process. Create a lather using the soap and rub it gently all over your body. Let it settle for around 4 minutes (read the manufacturer’s instructions), and then rinse off using cool water.

As for using a kojic acid skin whitening soap for your face, things are also uncomplicated. However, you should be more careful, especially in your first days of the treatment. Dermatologists recommend beginning your treatment slowly to see if your facial skin can tolerate the kojic acid soap.
Thus, you should only let the soap for about 30 seconds during the first few days of your treatment and then extend this time incrementally following the 15-additional-seconds-every-3-days rule until you reach the threshold of 4 minutes per day.

Unlike other skin whitening agents like hydroquinone, kojic acid is considered safe for you and your skin, especially when used in moderation. Extensive studies have also shown that kojic acid is not a cancer-causing substance.

Last thoughts on how to use kojic acid for skin lightening – Precautions

  1. Make sure you maintain a balanced diet which is rich in vegetables, Vitamins (mainly A, E, and C which further help in skin whitening), and of course, water.
  2. No matter which skin lightening treatment you choose, one thing is for sure; you have to ensure your skin is protected from the dangerous sun rays. Without the melanin it produces, your skin is vulnerable, so always apply a high SPF sunscreen lotion to your treated areas. Also, never stay under the sun for long, while having a skin whitening treatment.
  3. You must strictly use your favourite kojic acid soap only once a day for your skin lightening treatment. Otherwise, your skin might get irritated and itchy.
  4. Never leave your kojic acid soap on your skin longer than the manufacturer suggests. This way you minimize the risk of skin irritation.
  5. Your kojic acid soap should contain kojic acid at a 1-2% percentage. Levels higher than these are less safe for your skin.
  6. Kojic acid can be combined with papaya fruit extract or glutathione for faster results.
  7. Kojic acid soap might make your skin a bit dry. Always use a moisturizer, preferably one that includes aloe vera or coconut oil. You can use our how to use aloe vera for skin whitening and how to use coconut oil for skin whitening guides for additional information.
  8. Can Kojic Acid Cause Acne? No! Kojic acid is considered as a treatment and not as a cause when it comes to acne. In fact, kojic acid can be used to exfoliate the upper skin layers and clear any clogged pores that otherwise would create pimples.
  9. Once you achieved your desired skin tone, do not stop using your kojic acid soap entirely. Instead, use it on a less frequent basis as a maintenance soap so that your dark spots do not come back in the future.
