Celebs were bringing their A-game to the Oscars last night: From the red carpet fashion, which was totally top notch, to the makeup (check out Jennifer Aniston’s natural look) and hair, no detail was left unattended to when it came to style.

There was one star in particular, however, who had to go above and beyond to make sure her look was picture perfect: Chrissy Teigen. As half of one of the night’s hottest couples, Teigen got some serious attention for rocking a bold, Angelina Jolie-esque thigh slit of her Zuhair Murad gown.

It was a daring look that only one with rather flawless skin could pull off — or at least, that’s what we thought. The Lip Sync Battle host has been far from shy about revealing her own imperfections in the past (you might recall her previous shout-outs to her own stretch marks following the birth of little Luna), and last night proved to be no exception.

Hours before the big event, Luna’s mommy took to Snapchat to reveal a gnarly sore from a burn on the very leg she would soon be showing off to the world. Since Band-Aids aren’t exactly red carpet attire, a genius member of her beauty team thought fast and dusted some milk of magnesia (which you can pick up for about $4 at Walmart) to prime the offending spot.

Apparently, as Refinery 29 pointed out, it’s a well-known secret among beauty pros and works as a primer on all skin types to minimize pores and keep foundation from changing colors. But be warned! It’s a good emergency treatment, not great for long term, mainly because of its very high pH level. Your skin’s acid mantle ranges from 5-8 pH, but milk of magnesia is 10.5 pH.

It certainly seemed to do the trick for Teigen’s leg: We were totally impressed with the results. Ow, ow, Chrissy — your gams look great!

Have you used milk of magnesia as a primer before? What did you think? Sound off over @BritandCo.
