Skin redness and bruise - is there any way to correct this? (Photo)

i am 30 year old mans and underwent rejuran skin injection. I was told that swelling and erythema should be subside by 48 hours. This is day 5th post procedure and I still have a lot of red mark(like post acne) and bruise at both cheecks. It is normal. Are there any over the counter that can reduce this redness.
