The mechanism of action includes its impact on the production of melanin. Melanine is a natural pigment in the body that is responsible for eye, hair and skin coloring. Melanin synthesis requires the amino acid tyrosine.
Kojic acid functions by inhibiting the formation of tyrosine, reducing melanin production, which may result in skin lighting.
Usually found in cosmetic formulations such as creams, lotions and serums, kojic acid is also present in some soap, mainly designed for use on hands or face, but can also be used on other body parts such as legs and arms. Cosmetic products contain typical kojic acid concentrations ranging from 1 to 4 percent.

Safety
Before they contain products that contain kojic acid, it is crucial to guarantee their safety.
Unlike medicines and foods, cosmetic products are not regulated in the same way. They are not obliged to be approved by the FDA before they are sold.
However, there is a voluntary registration program for cosmetic manufacturers so that companies can reveal their product processes. In addition, the Cosmetic Ingredient Review (Cir) Panel evaluates safety.
Studies on mice have suggested a potentially connection between high concentrations of kojic acid and tumor growth, but this link is considered weak because the acid is slowly absorbed in the body. It is unlikely that levels would reach a point to cause cancer in people.
According to reviews, products with 2 percent kojic acid concentration for skin application are generally considered safe. The Cir -Expertpanel also supports the safe use of kojicic acid in cosmetics.
Raw kojic acid is available, but is not recommended for direct use of the skin. It must be diluted to no more than 4 percent concentration, preferably 1 to 2 percent to minimize skin irritation.
Adding raw kojic acid to creams or lotions can be a challenge and can lead to annoying skin levels. The use of products made with specific kojic acid concentrations is a more advisable approach.
Risks
Although products that contain kojic acid are generally considered safe for most people, there are potential risks and side effects to be aware:
- Increased sun sensitivity: Kojin acid can make the skin more susceptible to sunscreen. Because it inhibits the production of melanin, which helps protect against UV rays, the skin becomes more vulnerable to sun damage.
- Contact dermatitis: Some people, especially those with sensitive skin, can experience contact dermatitis when using kojic acid. This condition can manifest itself as a rash, itching, dry spots and in severe cases, pain and blisters.
The concentration of kojic acid in various products such as creams, serums and soap can vary between manufacturers. Higher concentrations can increase the risk of skin irritation.
Conclusion
When considering a kojic acid facial wax, it is essential to weigh the potential benefits against possible risks. Although kojic acid can offer benefits, such as skin lighting and tackling certain skin conditions, such as melasma and scars, it also brings risks with, such as increased sun sensitivity and potential for contact dermatitis, especially with higher concentrations. That is why people with sensitive skin or who are susceptible to sunburn must use caution and consult a dermatologist before taking a kojic acid facial wax in their skin care routine.
