I has herpes zoster. It's been a month now. The crust fell off. But what is left are holes. Will they go away with time?

I did apply for medication very soon. So it's not much. It on the right side on my face. there are 5 holes in count. How do i get these holes to fill. Doctor has advised me a cream called RET-HC. Which has helped. But it is taking lot of time. Will my holes fill with time? Help me please? holes were very deep before. But with use of this cream RET-HC. My holes have shown significant improvment. But i want them gone. Will they go with time? Or hs something else to be done. Please help me.
