Skin Lightening and Kojic Acid

Kojic acid is a very popular skin lightning and bleaching agent right now. It is a natural crystal like substance that is used in a lot of cosmetic products. It is usually found in a cream form and mixed in at different percentages with the cream between 2 and 4%. As far as commercial skin lightening products go, kojic acid is one of the better substances to use to whiten your skin. So if you are wondering how to lighten scars or how to bleach skin on your face or other parts of your body than kojic acid may be a solution for you.




Skin Lightening and Kojic Acid




Kojic acid is a by-product in the fermentation process of malting rice, for use in the manufacturing of sake, the Japanese rice wine. It is a fungal metabolite commonly produced by many species of Aspergillus, Acetobacter and Penicillium, and has been shown to act as a competitive and reversible inhibitor of animal and plant polyphenol oxidases, that catalyzes the conversion of tyrosine to melanin. Kojic acid inhibits melonasis by interfering with the uptake of oxygen required for enzymatic browning. What this means is that kojic acid treats hyperpigmentation and melasma in areas of the skin with too much melanin.  


The body naturally produces a pigment known as melanin through specialized cells known as melanocytes. Our genes produce the same amount of melanin, but how much of it gets processed determines our skin color. In people with fair skin, only small amounts of melanin are processed by melanocytes, while larger amount of the pigment are made by the cells of those with dark complexions.


Moreover, the production of melanin does not occur in fixed amounts. The production is increased in response to environmental or internal conditions such as: sun exposure (causing the skin to tan), inflammations (common among acne sufferers) and pregnancy. Repeated exposure to the sun can result in a permanent increase in melanin production in spots on the skin, causing small freckles and larger sun or age spots to form.

When kojic acid is applied to the skin in concentrated amounts, the chemicals in the ingredient work on the melanocytes, interfering with the production of melanin. In addition to its skin-lightening abilities, kojic acid is classified as an antioxidant. This class of nutrients has the ability to counteract the effects of particles in the air called free radicals, which have the potential to cause oxidative damage to the skin cells. By limiting the effects of free radicals, kojic acid helps to prevent the formation of signs of aging that occur when the cells that produce the skin’s vital structural proteins become damaged.

Is kojic acid safe?We have to be very careful about what we put on our skin so as to not damage it. Everything that comes into contact with your skin can be absorbed into your blood stream and circulated through your body. And some products are poisonous. There are ingredients in skin whitening products that you must be aware of, such as hydroquinone. Hydroquinone has been banned in European countries because it has been found to be a possible carcinogen. Unfortunately not all countries have this ban on the ingredient though, but one would wonder why not. It’s important to be aware that just because a product is on the market that does not mean it is a safe product. When it comes to your health, you are your strongest advocate. It is important that you take the time to really research what goes into the face bleaching cream you use.

In light of the hydroquinone debate, manufacturers are finding safer ingredients to add into bleach for skin products. It is important to look for compounds that are made from natural sources instead of using those that are manufactured from unnatural products. Kojic acid skin lightener fits the bill of that description. Kojic acid can be found in several skin lightener products. Research shows that when kojic acid is used in cosmetics it is safe as long as the product density does not exceed 2% concentration. Higher concentration levels could result in toxicity in the body. Other research shows that a 1% concentration is not as effective as the 2% formulas. So if you choose to go with kojic acid cream, it is best look for the 2% type. Oh and it should be noted that if you have cuts or broken skin or peeling this is not considered safe for application and you should avoid using products with the ingredient in it.


What are kojic acid side effects? As with most products, there can be some side effects that can occur with the use of kojic acid skin lightening cream. In some instances kojic skin lightening cream has been known to make a user’s complexion lighter than what they expected it to be. One must be careful while going out on the sun, due to higher chance of sunburn. But people who want lighter complexion shouldn't be out on the sun to begin with)))). There might also be some slight inflammation, redness, or itchiness from using kojic acid containing products. For those that are experiencing these types of symptoms, you should consider switching to the lower concentration.


 How long does it take to see results from kojic acid? Usually, it takes up to 3 months to see real results because all the older darker skin must be shed and be replaced by the new lighter one. Also, using a higher percentage products would produce a much quicker and more dramatic results.
