My 5 Year Old Had Chicken Pox Over 3 Months

My 5 year old had chicken pox over 3 months ago. One on the end of the nose got knocked off accidentally and there is a slightly indented scar which is still rather red. Is there anything I can do to reduce the appearance or is it likely to fade/stretch out as my child grows? I have been using bio oil aloe gel and makuna honey......Thanks in advance.....
