On the days I absolutely don't want to wear any makeup but would like to reduce the redness of some fresh pimples, the Dr. Jart+ Cicapair™ Tiger Grass Serum ($46) is my go-to. I owe one of my best friends credit for this one. Back in April, she sent me a series of Snapchats of herself wearing this serum, and I could've sworn she was wearing a full-coverage foundation her skin was that smooth. With that, I was convinced.
