• Customers who want an ingredient to build a targeted skincare formula

This product is not for:

• Anyone looking for a ready-made, finished skincare product
• People wanting immediate, overnight results from a single use
• Simple oil-only formulations, as this ingredient is best suited to water-based or emulsified products
• Those who prefer to avoid actives that require careful stabilisation and protective packaging

• As a Serum Active: Use at 1% in a water-based serum, adding during the cool down phase.
• As a Cream Active: Use at 1% in emulsions, adding during cool down once the mixture has dropped in temperature.
• As a Dissolution Aid: If needed, gently warm the water phase to 25 to 35°C to help the powder dissolve.

Processing Tip: Use antioxidants such as Vitamin E and ferulic acid to help stabilise kojic acid, and package finished products in dark, protective containers to reduce exposure to light.

• For external use only.
• Avoid inhaling powder and avoid contact with eyes.
• Patch test before first use and discontinue if irritation occurs.
• Do not use on broken or irritated skin.
• Store tightly sealed, away from heat and direct light.
• Because brightening actives can increase skin sensitivity, daily sun protection is recommended when using leave-on products containing kojic acid.
• If pregnant or breastfeeding, consult a qualified healthcare practitioner before use.

Q: Why does packaging matter with kojic acid formulas?
A: Kojic acid is sensitive to light and heat, so dark, protective packaging helps preserve formula quality and performance.

Q: Can I use kojic acid in a toner or facial mist?
A: It can be used in water-based products, but stability and packaging become even more important. A leave-on serum or cream format is often easier to stabilise and apply evenly.

Q: Can I combine kojic acid with other brightening ingredients?
A: Yes, it is commonly paired with other tone-supporting ingredients, but compatibility depends on pH, stability needs, and overall formula design.

Q: What should I do if my product changes colour over time?
A: Colour change can indicate oxidation or instability. Review antioxidants, reduce heat exposure during manufacturing, and switch to more protective packaging.
