Very sensitive skin/allergies, sensitive balsam.
Just something I've fully discovered which might help others in same boat. Been away from home a few weeks now, left my thayers breakable bottle and straights at home because don't like risking my strops travelling.
Been using de and supermarket own brand sensitive balsam, only one I could find without chamomile, I already knew was allergic to that. Upon application was noticing a tingle, thought nothing of it, used to thayers with alcohol, on second day looked as though had peeling sunburn, I'm also allergic to this 'sensitive' balsam. Used whiskey for a day or two, only thing in house and now using some cheap Axe alcohol based aftershave also problem free.
Just thought worth mentioning that though some of these things are marketed as for sensitive skin and hypoallergenic, it does Not mean it's true in every case.
Have fun shaving.
