Kojic Acid - 25G

Essentially Natural Kojic Acid is a cosmetic active commonly used to support a brighter, more even-looking complexion. It is widely used in skincare formulas aimed at improving the appearance of uneven tone and the look of dark spots over time. Kojic acid is typically formulated into serums and creams and is best added during the cool down phase to help maintain stability.

Because it is sensitive to light and heat, thoughtful formulation and protective packaging are important.

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.

Safety Instructions 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. FAQs 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.
