What Is Kojic Acid Powder?

Kojic Acid is a potent skin lightener, that has been used for decades by individuals all across Asia and South East Asia. It lightens the skin by inadvertently inhibiting tyrosinase activity - the enzyme responsible for producing melanin. In addition to its skin lightening benefits, it also has anti-microbial properties. It is the preferred natural, and highly effective alternative to hydroquinone.  


Kojic Acid Powder is compatible with SepiWhite, GigaWhite, Alpha Arbutin, and Kojic Acid Dipalmitate. Although Kojic Acid isn't a BHA or an AHA, you may wish to avoid mixing it directly with Vitamin C to avoid possible irritation. (Vitamin C & AHA's should not be mixed together).

Note: Avoid mixing too many powders into one lotion, aim for no more than 3 active skin lightening ingredients in one formulation.  

Guidance & Precautions

To add Kojic Acid powder to your skin lightening cream or natural brightening lotion, it involves a simple 4 step process.

1. Ensure all your ingredients ready. 1) Any base cream (skin brightening/lightening lotions work best) 2) Kojic Acid powder 3) Vegetable Oil. You will also require two pots (a smaller and a larger one) to mix and dissolve the powder with the oil.

2)  Mix 1-2teaspoon (about 5-10 grams) in with a small amount of vegetable oil or any oil. Glycerin can also be used. Do not use water.  Place the mixture into a stainless steel pot, and use the double boiling method. Place the pot on top of another pot with warm water under heat. Mix, and wait until the powder has fully dissolved with the oil (it should not be grainy or powdery). 

3) The mixture will take on a buttery, creamy color. Once the mixture is clear, you will know the powder has fully dissolved.

4) Add the fully dissolved powder (with the oil) into your base lotion until it's fully mixed together. Add a little at a time, until it's all completely absorbed. 

Voila, you have just turned an ordinary brightening lotion, into a potent skin lightening lotion which you can use for at least 6 months.   Repeat the process as you wish.  Adding Alpha Arbutin powder will increase the potency of the lotion.  


Kojic Acid, like Alpha Arbutin does not have any known side effects, and is generally safe for most people. 

However, this product is not intended for internal use.  Do not add the powder to products containing lactic acid, or AHAs as this can affect the pH balance of the lotion. If redness, itching, or irritation occurs, discontinue use immediately.

Percentage & Usage

You should aim to use no more than 2-5% of any of our skin lightening additives in a single formulation. Using more than necessary can be counterproductive. Calculating percentages in a lotion is very straightforward, and guidelines have been shown below.

To make a 2% lotion, use 2grams of the Kojic Acid Powder in a 100gram base lotion.

To make a 5% lotion, use 5grams of the Kojic Acid Powder in a 100gram base lotion.
