If there's a star who really is "just like us," it's Mindy Kaling. Not only does the real-girl celeb own at shutting down the haters and giving badass advice, but she's also a fan of a good ol' DIY-beauty treatment. Today on Instagram, she revealed her favorite face mask to use on her "mega oily skin," and it only involves two ingredients: Bragg's Apple Cider Vinegar and Aztec Secret Indian Healing Clay. Add 'em up and the mixture costs just over $10, a far cry from the expensive beauty regimens of many Hollywood celebs. It's no wonder The Mindy Project star is taken with the mask. After all, apple-cider vinegar is a proven astringent, making it ideal for those with oily skin. The second component — bentonite clay — is equally beneficial. The clay, when mixed with a liquid like apple-cider vinegar, has deep pore-cleansing abilities (not to mention a near cult following). But if you ask us, the best part of Kaling's post is her praise for the treatment's ability to make her look "frightening." Because, let's be real: That's half the fun of DIY spa days.
