What is Kojic Acid.

Kojic acid is a chemical produced from different types of fungi. It is also a by-product of fermented soy sauce and rice wine. It takes a powder form.
Kojic acid can be found in a number of different types of cosmetic products, including serums, creams, cleansers, and soaps.

Kojic acid soap is one of the most used skin Lightening soap by users, because of it’s effectiveness towards lightening the skin. Kojic acid not only evens and lightens the skin, it exfoliates the skin and also gets rid of age signs (though Kojic acid is not really an anti-aging ingredient) but I does fight skin aging signs and controls skin blemishes.

Kojic Acid is a natural antioxidant and helps protect skin cells from oxidative damage and also works as an antibacterial agent and will kill bacteria that causes acne and blemishes.

When using Kojic acid soap, it cleanses the pores by exfoliating and getting rid of dead skin cells dwelling on the skin, and also getting rid of impurities blocking the skin pores. Thereby keeping the skin pores clean and free from radicals.

There are two types of kojic acid. They are:

  • Kojic acid and
  • Kojic Acid Dipalmitate.

What’s the difference between the two?.

  • Kojic Acid itself oxidizes quickly when exposed to air, heat or light. But asides that, it’s very effective in lightening the skin.
  • Kojic Acid Dipalmitate is a more stable form of Kojic acid. It is a modified kojic acid derivative which not only overcomes the instability to light, heat and metallic ions, but also keeps the excellent property of inhibiting the activity of tyrosinase in the human skin and prevents the forming of melanin. It is more efficacious than straight kojic acid. Many companies use kojic acid dipalmitate because of its stability in nature.

How Does Kojic Acid Works.

Kojic acid being a better alternative to Hydroquinone, works by inhibiting biochemical processes and enzymes that are involved in producing melanin (dark skin pigment) in the skin. By interrupting the production of melanin (known as melanogenesis) the skin will eventually begin to lighten.

Although, Kojic acid being a natural ingredient, seeing visible results may take some time. But with regular usage it will effectively improve complexion, fade dark skin and skin pigmentation.

Kojic acid is 100% natural its effect are reversible and do not damage cells or function. Melanin production resumes once Kojic Acid usage stops.

How to Properly Use a Kojic Acid Soap.

  • Before using any Kojic acid soap, we advice you wipe off your make up.
  • Splash a warm water (not hot) on your face to open the skin pores.
  • Massage the soap onto your skin for 15 seconds during the first week of usage. Increase this to 30 seconds during the second week. Then when your skin must have gained tolerance, you can increase to 1-2 minutes. Wash with cold water afterwards to close pores.
  • Avoid getting the soap in your eyes, nose or mouth (This can sting real bad) if it gets into these areas wash off immediately.
  • Use the soap once a day during the first week. If you should experience redness or skin irritation, then only use the soap every other day. Example: You use on Monday, skip Tuesday, use on Wednesday, just like that.
  • Apply thick water based (oil free) moisturizer to prevent skin from drying out and feeling itchy and tight (due to the skin peeling effect).
  • Avoid the sun. While using kojic acid soap your skin will be more sensitive and more prone to UV damage. Always Use sunscreen while stepping outside, with at least SPF 30.
  • Store the soap in a cool and dry place, we prefer you store the soap in a sealed container. Kojic Acid oxidizes quickly making it less effective.
