Off on hols soon and trying to find sunscreens that whole family won't react to. DH and I get a prickly heat type rash if we use waterproof ones, and ds seems very susceptible to heat rash so want to find him a good hypo-allergenic one. Went in to Boots today and the selection was very limited. Is there anywhere on the net that will deliver in days or a department store reknowned for huge selection to choose from? Also - any tips on good brands? Cheers my dears
