Although most makeup is hypoallergenic, this only means that it has been shown to cause less allergic reactions in those who suffer from allergies. Nothing can be said to cause no allergic reaction in everyone, so it is very possible for someone to have an allergic reaction to a concealer. As far as what ingredients would cause that reaction, it could be anything from the base, which is usually some sort of cream or oil, to the fragrance, if there is any, down to the coloring that was used to get the concealer to the proper shade.
Nowadays there are so many types of makeup you don’t have to rely on one type of concealer because there are various forms of concealers out there to try. First of all there is the traditional concealer which comes in a tube resembling lipstick, but you can also try a mineral based concealer, which comes in powder form and you brush it on, and there are also concealers that are more liquid based, coming in a tube with a foam applicator, such as a lipgloss. Between these three suggestions, you should be able to find one that will not cause an allergic reaction, especially if you try different brands.
