TCA cross redness - will Pico laser help as well as RF Microneedling?

I’m asian and underwent 6 TCA Cross treatments for my chickenpox scars (last treatment was 2 months ago). It had outstanding results as it’s flat. However, one scar seems to have persistent redness while others is already my skin tone… Will pico laser help as well as RF Microneedling? The one with redness also has somewhat of a texture so RFM maybe helpful? Thank you!
