OT: Sunburns

My daughter gets married in exactly two weeks.  She was gardening in a tube top (she didn't want tan lines).  She is always very careful with sunscreen but this time put sun screen every where but forgot her back.  She has a sunburn going down the whole length of her back (except where her top was).  Her back will be visible with the wedding dress on.  

My question is....how long does it take for a sunburn to heal?  Will her sunburn be healed in two weeks?  Will her skin still be pealing?  I bought her some aloe for her to put on her back every day.   

 She will be fine in 2 weeks. Aloe is wonderful. Peeling should be over by 1 week. Moistureize, several times a day. Benadryl for the itching or oatmeal baths so she doesn't scratch and create a worse problem.
