A little trick I've discovered: If you, like me, get little red dots around your eyes (burst blood vessels) from vigorous puking, try a little witch hazel morning and night. Works wonders. As a bonus, you can use the witch hazel as a toner on pesky pimples, since "they" (the powers that be) do not recommend using salicylic acid while pregnant. I like Thayer's because it has lavender in it.

When the bruising was especially severe, I let the witch hazel dry, then gently patted on some arnica. I found the spots went away quite quickly with this treatment.
