What is this rash from sun on accutane? (photo)

I am on my last month (5th) of accutane, nothing but a little bit of scarring left. I woke up the next morning after swimming with small, clear bumps on my temples. They have then spread to everywhere on my face and onto my neck becoming more red, dry, and scaly. It has been 3 days, however it is only on my face, neck, and around my ears. They are pretty much clear bumps for the most part. They make my face feel very scaly and are everywhere. What is on my face and how do I treat it? Hard to see
