Hello, I suffered from chicken pox and its been around 10 days since i recovered completelyx. I have some scars on my face and some of them have blackened with time. There are also quite a few marks on my chest. I was advised to use eumose cream and kojiglo cream on the marks by Dr. Mrinal Gupta and have been applying both for 5 days now. There hasn't been any improvement till now. How much more time will it take for the scars to heal completely? How much longer should i continue using these medicines?
