You know how celebs manage to look as flawless on the red carpet as they do posing in another blemish-free #nomakeup selfie? That’s because of the hero product Hollywood’s skin guru uses on her high-profile clientele (which includes Emma Stone, Naomi Watts and Zac Efron to name a few). It’s Lina Hanson’s Global Facial Serum and you’re going to want to pick up a bottle, stat.

We deemed this serum the holy grail of beauty products because it works on every skin type and its designed to help boost your mood. Really! It’s made with essential oils that relieve anxiety (but judging from its super powers of reducing the appearance of fine lines and boosting skin’s elastisticty, of course we’d be feeling happier!).

You can also use this to double as a makeup primer and if you have super-sensitive skin, the serum isn’t known to cause any increase in breakouts.
