Benefits
Skin lightening |
Kojic dipalmitate is more efficacious than kojic acid in inhibiting the activity of tyrosinase present in human skin so as to inhibit the melanin formation and produce excellent effects in whitening skin and in anti-suntan. |
|
Solubility and skin absorbance |
Kojic acid dipalmitate is oil soluble and is more easily absorbed into skin when it is incorporated into a cream as compared with kojic acid |
