What Is Kojic Acid And How Does It Work?
Kojic acid is a chemical product or natural metabolite, derived from a variety of fungi. It is also produced from the fermentation of certain Asian foods like soy sauce, rice, wine, and Japanese sake. These food items act as a primer for the fungus. Kojic acid is fundamentally a skin whitening, lightening, and depigmenting agent. This is possible with kojic acid’s tyrosine (an amino acid) inhibiting properties, which essentially restrain the synthesis of melanin. Sun exposure, hormonal imbalance, aging, or medication, can cause discoloration and pigmentation on the skin. As an antioxidant, anti-inflammatory, and anti-proliferative, agent, the derivatives of kojic acid efficiently combat photodamage, excess pigment production, discoloration, and oxidative stress by repairing the cells and reversing the harm (1), (2).
Amazing Benefits of Kojic Acid for Skin
The cosmetic perks of kojic acid are not limited to mitigating hyperpigmentation and melasma on the skin. Available in different forms in the beauty industry, with a bevy of uses, here are the major benefits of kojic acid you need to know about.
1. Lightens the Skin: Lending an anti-aging effect, the kojic acid efficiently lightens the signs of photodamage on the skin, along with age spots and scars (1).
2. Helps Fight Acne: Kojic acid’s antimicrobial effects are valuable for treating acne caused by bacteria in the skin and also lighten the tough scars from acne. Besides these, there are antifungal and anti-inflammatory properties attributed to kojic acid, which are effective in combating fungal infections like yeast infection on the skin, candidiasis, and athlete’s foot (1).
3. Cleansing Proprties: Soaps or body washes crafted with kojic acid, when used regularly are also helpful in the prevention of infections on the body, caused by bacteria and fungus (1).
4. Evens Discoloration: The hero feature of kojic acid is to fade and blur the discoloration of all types on the skin, thereby reversing the appearance of uneven skin tone. Topical treatments containing kojic acid work on dark spots, melasma, hyperpigmentation, and sun spots (3).

If you want to use products containing kojic acid to treat a certain condition, make an appointment to see your dermatologist. They can help you decide about the best and safest course of action. They can also provide you with information about dosage and complementary treatments. If you experience any redness, rashes, irritation, or pain when using kojic acid, stop using it immediately.
