As a skin lightener, kojic cream works by acting on the root cause of skin discoloration and pigmentation. The dark spots and pigments on the skin are actually clusters of melanin, which are the skin’s form of defense against different factors like sunlight, friction, and aging. Melanin is created through the synthesis of tyrosinase, and kojic acid counteracts the production of melanin by preventing tyrosinase from synthesizing. As a result, the skin will not be able to produce melanin, and there will be no more dark pigmentations present on its surface.
Because kojic acid is a natural substance derived from natural processes, kojic acid is not harmful to the health of humans. It is comparatively better than hydroquinone, its closest counterpart as skin lightening ingredient, which has been banned in several countries because of its cancerous effects. But kojic acid also has some negative effects on the skin.
Excessive or long-term use of kojic acid skin lightening products may cause skin irritation, and continual use after irritation may lead to allergic contact dermatitis. That is why it is advised to use kojic acid in very small amounts only. The substance is definitely effective so even in small amounts, it will show significant results. And once the satisfying results have been observed, it is best to stop using the product and maintain the skin complexion instead using sunscreen.
Although kojic acid is effective, it has some side effects, which only goes to show that there is really no perfect product to provide the best solution for skin lightening. There may be other forms of skin lighteners, but none of them can really be said as better than kojic acid. They may work as well, but they will also have side effects. That is why it is best to be satisfied with the body that you have been given. If you really don’t need whiter complexion, you don’t have to make your skin color a problem so you wouldn’t have to look for a solution.
