Adding Whitening Ingredients to Lotion

It is generally possible to add ingredients like Kojic Acid, Alpha Arbutin, and Vitamin B3 (Niacinamide) to a ready-made body lotion.

However, it is crucial to check the ingredient list of the existing lotion. Some ingredients in the base lotion might be incompatible with the additives, potentially causing issues like instability or reduced effectiveness. As the staff mentioned, providing the lotion's ingredient list would allow for a more specific compatibility check.

If the ingredients are compatible, you can typically mix them into the entire batch of lotion at once, rather than mixing small amounts each time you use it. This is possible as long as there are no incompatible components.

Most importantly, you must strictly adhere to the recommended usage rates for each ingredient:

• Kojic Acid: 0.1-2.0%
• Alpha Arbutin: 0.2-2% (recommended 2% for whitening)
• Vitamin B3 (Niacinamide): 1-10% (recommended 5% for general benefits, up to 10% for high-purity grades like Safe-B3™)

Using concentrations higher than recommended can lead to skin irritation or other adverse effects and should be avoided. Always follow the guidelines provided for each specific ingredient.
