As to horseradish, there might be some mistake. I switched from MILD to SPICY (grated horseradish (52%), filtered water, vinegar, rapeseed oil, sugar, salt, citric acid, modified starch, xanthan gum, sodium metabisulfite, and potassium sorbate). I also switched from 15 minutes per day of treatment time to a non-stop 168 hour treatment in a 168 hour period. However, horseradish did not do anything for my melasma.
