It's really the last frontier in celebrity over-sharing, you know. Famous people are open about everything else on Instagram, but one thing you don't see next to painstakingly composed shots of almond croissants? Eyebrow tweezing! Mustache bleaching! Here, we've rounded up some rare self-maintenance pics, from Karlie Kloss in curlers to Sofia Vergara being massaged by some suction-y contraption.

Justin Bieber

He's already won his first Grammy, but there's no such thing as too much preparation. Or too perfect a complexion. (FWIW, he's using the Talika Bio Enzyme Hydrating Mask.)

Kylie Jenner

Kylie promised to take us into her personal life, and take us into her personal life she did. In a series of Snapchats, the recent convert to small mouths has her eyebrows and upper lip waxed, much to the delight of her friends, who are there for some reason.

Kendall Jenner

Being swamped with NYFW, the 19-year-old model had to resort to shaving her legs in the back of a car substituting shaving cream for water. Ouch.

Miley Cyrus

Like pretty much everyone in 2015, Miley's blood type is avocado—so much so that she smashed one and used it as a moisturizing mask.

Chrissy Teigen

A flight is nothing if not an opportunity to make yourself prettier. Teigen knows this better than anyone, sporting a moisturizing (and fellow passenger frightening) sheet mask miles high in the air.

Say goodbye to the pit hair! Cyrus Instagrammed this shot, where the seemingly painful removal was revealed for all to see. (Including the "after." Be prepared for this one!)

Three lip masks is definitely a trend, especially when the other two are Lady Gaga and, well, us. *fluffs hair*

Lady Gaga

Preceding Lady Gaga's epic hair transformation, she prepped with a sheet mask, some oversize sunglasses, and her even more oversize Lorraine Schwartz engagement ring.

Lady Gaga

Then, while her hair lightened, the singer did "a series of plant stem cell masks and collagen lip jelly mask. Good for hydration and plumping with no 💉 or silly bruising!" Ooooooh, I see what you did there.

Victoria Beckham

While most of us are applying mascara with our mouths wide open, Victoria Beckham is poised and perfect with a wand at the ready. It's just not fair.

Miley Cyrus

Miley Cyrus isn't apologizing for growing out her armpit hair (you do you, Miley!) and she's even going as far as changing it up—showing off her "bleaching party" on Instagram. "Don't eat the bleach baby" she captioned the first pic, before debuting her new, pink armpits.

Touch-ups count, especially when you've spent the last few months of your life tied up and blindfolded.

It's hard to believe Beyoncé painted all 10 nails, but she did do one, and it was for a good cause.
