You might consider concentrated vitamin C in a silicone base. I have indented scaring from electrolysis and it got much better over time, but it's still a little bit there. I didn't use anything! Mine were like needle holes. I feel like if i had made an effort to heal them they'd be better off. So i rec using something for 6 months while they're still new, no matter what it is whether it be retin-A or vit C.
Skinmedica vitamin C complex is very potent and stable in a silicone base. It' expensive though, $80 i think at skinstore.com, but they usually have 20% off codes.

oh, and one of the strongest retinols you can get, since retin-a is rx, is "green cream", google it, can be bought online. Very popular well loved product and one of the least expensive good retinol produts. About $45 on dermstore.com.
