Mole removal 4 months post op, scar is shiny and light pink, is this normal?

Hello, When will the shininess improve? 4 months ago I had radio frequency mole removal, at the moment my scar is light pink and slightly shiny. This shininess is making the scar hard to cover with makeup as it is slightly atrophic too. When will this improve? I have been using silicone gel for 3 months. What are my treatment options and how long should I leave it before I do something? Would microneedling be of benefit? Thanks!
