There may be a ton of unanswered questions on Pretty Little Liars, but in real life, Shay Mitchell (Emily) is finally revealing one of her secrets — the trick to super clear skin!

The glowing brunette actress was seen in the green room in Los Angeles earlier in the week, prepping her face with Bioré Acne Clearing Scrub. A little exfoliating clearly goes a long way!

As for what else Shay is up to besides making her skin look glamorous? For starters, PLL Season 4 starts filming on Thursday (March 14), so we're sure Shay is prepping for her close-up. On a more personal (and juicy!) note, Shay was spotted spending time with Glee star Jacob Artist earlier in the week. Could things be heating up between these two TV stars?

Maybe that crazy glow that Shay is rocking isn't just from face wash — wink, wink!

Catch the Season 3 finale on Tuesday, March 19, 2013 at 8 p.m. ET/PT on ABC Family.
