4 Weeks After Full Face Fractional Co2 Laser my Face is Very Sensitive. Options?

Hi. 4 weeks ater full face fractional co2 laser my face is still very sensitive and even cetaphil, sorbelene make it sting. I can't use sunscreen as it burns and my face has areas which are very tender to the touch on cheeks and forehead. I have more lines now under my eyes and deep hollows.My face feels very dry and tight. Can you recommend a hypersnesitive sunscreen? Dr put me on prednisone but not much improvement. Any advice and will this heal eventually? Thankyou
