Use sunscreen daily, apply multiple times per day, this will stop it getting any more red and allow it to fade. Tretinoin to increase cell turnover.. available on prescription    

@ally.m83I am moving this to hyperpigmenation sub. You have PIE or wounding post acne. This is very common and some have it for a year after. Vascular laser is the quickest solution but also expensive. Some people do Glycolic peels to lighten things, ... other's use nightly retin-a/(or)differin/(or)tretinorin. Castor oil would be more appropriate than coconut and that does not work for some. Take a look at the full list of treatments in the FAQ - at the top of the hyperpigmenation sub, it's pinned.
