Hi

I have a patch of AK between my eyebrows and have been prescribed Fluouroacil for 4 weeks.  The Dr said it will make my skin red/blistered and that I need to protect it from the sun. However, I think that suncream isn't supposed to be used on broken skin, so I may not be able to apply it in that small area?  It isn't always practical to wear a hat, so I'm unsure what I'm supposed to do? The cream was prescribed by a GP at a specialist clinic, and I don't have her contact details. 

Also, I am due to go abroad on holiday in 3 weeks' time, and don't know whether to postpone the treatment until after. On the other hand, it's a lot easier to wear a sunhat all the time on holiday, so that may be a better way of protecting my skin.  

Any advice would be appreciated.
