hello and welcome to hcm forum,
i would like to inform you that kojic is a whitening agent , you can use it to lighten up the scars
, also add oral antioxidants(once daily) for 4 weeks to your diet.
apply kojic twice daily, use a gel based sunscreen (2-3 times/day).
for enhanced results you can take 2 sittings of chemical peels
within a months time.
i wish you good health.
