If you’re a ’90s baby, chances are you had a collection of mood rings in your accessories box. Now MAC is bringing them back — but in lip balm form. No, it’s not a piece of jewelry but rather a product that changes colors when it interacts with the chemistry of your skin. Dubbed Tendertalk, the collection offers five shades in different variations of pink that will alter during wear while also hydrate and condition your lips. Find each one, priced at $20 USD a bullet, at MAC June 16.
