Scar Revision or Dermabrasion? (Photos)

I'm 22 yrs old. I have 2 chicken pox scar and I got them since I was a baby. The scar is not so deep. I was planning to remove it or to somehow make it less visible. So I was wondering which procedure should I go for? Scar Revison Z-plasty or Dermabrasion? I've been also using dermapen for 3weeks and I think I can see some improvement. But I want it to be less noticeable within the month if I wear a make up Thanks!
