I have been on 21 days of efudex. I have been using vaseline to ease the tightness and pain and it has worked well. I have finished using the efudex but now my face is swelling and very itchy. It is driving me crazy!! I will try the hydrocordozone mixed with vaseline that I read about here. I want to reccomend two things: Put your vaseline in the FRIDGE, it feels really good when you apply it cold! Also, for sunscreen you can use Vanicream Sunscreen. There are no added ingredients: no dyes or fragrance, formaldehyde, parabens or masking fragrances. It does not hurt (much) to put it on.
