Product Description
Kojic Acid is a natural-derived, high-purity (≥99%) cosmetic active ingredient produced through fungal fermentation (Aspergillus oryzae). It is a well-established, scientifically proven skin-lightening agent that works by competitively inhibiting tyrosinase, the key enzyme responsible for melanin biosynthesis in the skin. Unlike hydroquinone, Kojic Acid offers a safer, non-toxic alternative for treating hyperpigmentation disorders without causing permanent skin damage. Its mild antioxidant properties also help protect the skin from oxidative stress, making it a versatile ingredient for both brightening and anti-aging products. As a stable, water-soluble crystalline powder, it integrates seamlessly into emulsion-based and water-based cosmetic systems, delivering consistent performance across a wide range of final formulations.

FQA (Frequently Asked Questions)
Q: What is the mechanism of Kojic Acid for skin lightening?
A: It inhibits the enzyme tyrosinase, which is essential for melanin production in the skin, effectively reducing pigmentation at its source.
Q: What is the recommended usage level in cosmetics?
A: The typical recommended dosage is 0.5% to 2.0% in the final formulation. It is recommended to start at 1-2% to minimize the risk of skin irritation.
Q: How should Kojic Acid be incorporated into formulations?
A: It is water-soluble and should be added to the warm water phase of the formulation at temperatures between 25-40°C (77-104°F) to prevent oxidation and loss of activity.
