What does kojic acid do to your skin?
1. Kojic acid's skin-lightening and whitening effects.
Because it can snatch copper ions released by melanocytes, it can prevent the formation of dullness from the source by inhibiting the synthesis of tyrosinase, thereby achieving whitening and brightening.
Kojic acid enters the skin and snatches copper ions from tyrosinase, making tyrosinase inactive, thereby blocking the production of melanin, achieving the effect of whitening and lightening spots, and has a significant effect on inhibiting facial melanin and spots.
Therefore, kojic acid can be added to the formula of essence, mask, lotion, and skin cream to improve freckles and chloasma. Kojic acid is very sensitive to acid, so in product matching, avoid ingredients such as salicylic acid, fruit acid, and high-concentration VC, and it is best not to use them in combination.
This ingredient has good compatibility and is suitable for compounding.
2. Antioxidant
Kojic acid also has the effects of scavenging free radicals and anti-oxidation. It can help tighten the skin and promote protein coagulation.
Even due to its antioxidant properties, it can be used as a preservative in food and cosmetics.
However, kojic acid has poor stability, is afraid of light and high temperature, is easily decomposed and oxidized, is somewhat irritating, and may damage the skin barrier.
