Kojic Acid Soap Review: Is It The Best Skin Whitening Solution?

When you look for skin whitening solutions, you will see posts for kojic acid soap review. Kojic acid is a popular active ingredient for products that whiten and brighten skin. It is first isolated from fungi Aspergillusoryzae, as a by- product of a fermentation process in sake manufacturing.

Kojic Acid Uses

Before gaining notoriety in the beauty industry, it was a natural product that is normally used as a food preservative. Kojic acid had less side effect compared to laboratory synthesized food preservatives, and cost less to obtain as it was a byproduct of fermentation. Kojic acid uses:

  • Stop fruits from oxidative browning, particularly after cutting
  • Keeping color of seafood looking fresh, it avoids color fading
  • Added into food to keep it fresh, as it keeps cells healthy

Beautifying Effect Of Kojic Acid

It is more common to have a concentration of 0.2% kojic acid in beauty products, although it can go upto 1% for a strong effect, as it is a 98% pure substance. Most manufacturers find that any higher concentration can have side effects such as skin irritation. Kojic acid is used to:

  • Dissolve stubborn grime in pores as an acid, making it easier to be removed later.
  • Exfoliate skin as it can strip off dead skin layers, revealing new layer beneath. Hence it reduces appearance of hyperpigmentation, scars and melasma.
  • Enhance skin cell renewal to promote new skin cell growth.
  • Inhibit enzyme tyrosinase, which induces production of melanin, a pigment that darkens skin, a useful skin whitener.

How To Use Kojic Soap

One of the ways to use kojic acid in your beauty regimen is in the form of soap. There are a few brands that makes this soap in varying concentrations, so bear that in mind when you buy one. To start, dampen skin with lukewarm water to open up the pores, so that the product can be more effective.

Initially stage: if you are trying to test kojic soap for sensitive skin, then start using it once daily, and do not leave the soap on for more than twenty seconds. You can repeat daily until your skin is used to it. Never rub the into the skin, only gentle circular motions to lift grime away.

Sometimes you can feel a tingling sensation, but it should not feel like your skin is burning off. When that happens, it means that you are having a reaction to kojic acid and therefore you should discontinue using.

Second stage begins when you can use it as directed, or twice a day with the same time limit. You can also try to extend the time by leaving it in five to ten second increments. You can repeat and increase the time until you are able to tolerate leaving the soap on for around one to two minutes.

After you rinse off, always follow up with a good quality heavy moisturizer, as you need to replace the skin’s natural hydration. When using this soap, always apply sunscreen and practice staying out of the sun.
