Kojic Acid in short
Derived from fungi used in rice wine and soy sauce production, kojic acid blocks the enzyme that makes melanin. It is effective on dark spots but can cause contact sensitivity in some people.
Vitamin C in short
A powerful antioxidant that brightens dull skin, fades dark spots and boosts your sunscreen's protection against free radicals. Pure L-ascorbic acid works best at a low pH and oxidises (turns orange) quickly.
