Product Description
What Is Kojic Acid?
Aspergillus oryzae is one of the fungus that naturally generate kojic acid, a substance that is frequently found in medicinal and cosmetic products. It can lighten skin by acting as a chelation agent and blocking the tyrosinase enzyme, which is in charge of producing melanin. Additionally, kojic acid is well-known for its antioxidant qualities and capacity to lighten skin by minimizing hyperpigmentation.
Preparation Method:
Kojic acid is typically synthesized through fermentation processes using microorganisms such as Aspergillus species. In these processes, starch or sugar-rich substrates are fermented to produce kojic acid. Alternatively, it can be synthesized chemically via reactions involving sugars or derivatives of aromatic compounds. To reach the required purity levels for application in cosmetics and pharmaceuticals, the chemical is subsequently refined using crystallization or other refining methods.

Kojic Acid Has Wide Range of Uses:
Skincare:
Kojic acid is used in creams, serums, and lotions for skin brightening. By suppressing the synthesis of melanin, it lessens melasma, dark patches, and hyperpigmentation, leaving the skin tone more uniform.
Pharmacy and medical:
Found in antifungal creams and ointments, kojic acid helps treat fungal infections like athlete’s foot and ringworm, thanks to its powerful antifungal properties.
Food Industry:
Used as a natural preservative in food products, kojic acid prevents browning and oxidation, helping maintain the freshness of fruits, juices, and beverages.
Hair Care:
Kojic acid is included in shampoos and conditioners to combat dandruff and promote healthier scalp conditions due to its antifungal effects.
User Asked Question:
Q: What is the difference between Kojic Acid and Vitamin C?
A: Kojic Acid and Vitamin C both have skin-brightening properties, but they work differently. Kojic acid works well to treat pigmentation and dark patches because it prevents the synthesis of melanin. Vitamin C, on the other hand, is an antioxidant that helps brighten skin by neutralizing free radicals and promoting collagen production. Vitamin C is generally gentler and suitable for sensitive skin.
