The CIR Expert Panel agreed that kojic acid could be safely used in cosmetic products. Raw kojic acid is available, but it is not recommended for skin use. Kojic acid should be diluted to concentrations of no more than 4 percent. A concentration of 1 to 2 percent is recommended to reduce the chance of skin irritation.
Use the product once a day only. After a few weeks, you can work start using it twice a day. Be patient with results. Everyone has a different skin type with different skin conditions, with some people having immediate results and others not.
The main benefit of using Kojic Acid is it lightens and brightens the skin. It also has anti-aging effects. Dr. Magsumbol explained, "Kojic acid's primary use and benefit is to lighten and or reduce hyperpigmentations like visible sun damage, dark spots, age spots, or acne scars.
You'll want to follow these instructions carefully, massaging the soap onto your face for at least 2 minutes for maximum effect. Then wash off with warm water.
Potential benefits
In addition to skin-lightening effects, kojic acid also contains some antimicrobial properties. It may help fight off several common types of bacterial strains even in small dilutions. This can help treat acne caused by bacteria in the skin. It may also lighten scars from acne that haven't faded yet.
Skin will eventually shift back to its natural state once you discontinue use, and trying to avoid that by using excess amounts of the ingredient can cause some serious irritation.
Kojic acid is similar to a chemical called hydroquinone. They are both effective treatments for hyperpigmentation. Treatment with kojic acid isn't immediate. For significant improvement, you'll need to use a kojic acid cosmetic for up to three months in some cases.
Kojic acid was deemed a “quasi-drug” and banned from the market in Japan by the Ministry of Health, Labor and Welfare in 2003 and subsequently in Korea and Switzerland due to safety concerns stemming from animal test results suggesting mutagenicity.

Yes, kojic acid is safe to use everyday. Depending on your skin's sensitivity, it can be used twice a day. Just remember, don't use kojic acid more than 3 months at a time because that can be damaging to your skin.
No, it cannot lighten your natural skin tone. It can only lighten pigmentation and dark spots or patches that appear on your natural skin tone.
Kojic acid is not cytotoxic (that is not harmful to living cells) and therefore cannot permanently lighten your skin tone. However, you can enjoy the results as long as kojic acid or kojic acid dipalmitate are used.
While you have to wash off soaps and cleansers immediately after application, you can leave kojic acid serum, cream, or lotion on overnight for better absorption.
While skin sensitivities range from person to person and exceptions certainly exist, as a general rule, kojic acid is considered a treatment -- not a cause -- of acne.
Kojic acid was not a toxicant in acute, chronic, reproductive, and genotoxicity studies. While some animal data suggested tumor promotion and weak carcinogenicity, kojic acid is slowly absorbed into the circulation from human skin and likely would not reach the threshold at which these effects were seen.
Is it safe to use Kojic acid and Vitamin C together? It is possible to use kojic acid together with vitamin C on your skin, however, if you have sensitive skin it is advisable to layer them separately in your routine.

Kojic Acid:
One of the most effective skin lightening treatments for treating lip pigmentation is kojic acid. Kojic acid is a great chemical which can help to block the production of color pigment, melanin, on the lips. Using creams, serums or scrubs with kojic acid can help to prevent further darkening of the lips.
Kojic acid takes at least four weeks to show results, so starting with that timeline in mind is a good idea. Post this, kojic acid has a high safety profile, so it can be safely used for a long time, even for months at a time without any side effects.”
If you have a red or brownish mark on your face that you got from a bad zit, it should eventually fade. However, it may take 12 months or longer. If you're upset about acne marks, talk to your doctor, who might have advice on what you can do.
