Fragrances, both synthetic and natural, can be an absolute minefield unfortunately. Some products still haven't phased out MI as a preservative. Many bath, shower, handwash and shampoo products still contain SLS or its close relatives. The problem is that not everyone reacts to these additions, and unless legislation is brought in to ban their use in any cosmetics and toiletries, you can struggle to avoid them. Far too many beauty brands and retailers do not include all the ingredient listings for the products they sell.
Then there is the further minefield that due to differing legislation, the products bearing the same name may have different formulations in different markets (true of all sorts of medication as well, so beware)... particularly noticeable outside of Europe. US regulation sometimes lags behind Europe, but sometimes Europe lags behind US regulation so you can't assume you are "safer" with US or European brands or that when you shop abroad you are getting a better or safer product.
Windowshopping - what are you able to use as a lipsalve if you have such a problem? I would find it a nightmare if I couldn't use some sort of lipbalm or lipsalve. Welcome back, anyway after your surgery. How horrible to have to go in in a rush, and not for the first time. Hope the recovery is going well.
