Why is the skin on my face turned red?

So I just took a shower and now my cheeks are red, its like many red dotts combines together and its huge. Both cheeks. Also, I had a bit of acne problem there but it was normal for 6 months… Also my forehead has acne scars I think that are reddish and darkish. My skin doesn’t look nice now. Theres a little blood vessel in the corner of my nose. What is going on man!
