2021 was a weird year for beauty. Like, really bloody weird.

Half of it was spent giving our skin way too much love (five face masks a day because NO RULES) while we were working from home, while the other half brought the return of in-person red carpets and awards ceremonies, as well as a renewed desire to do ALL the fun stuff with our hair our makeup.

Watch: Remember when we went back to our offices? And left our dogs at home? No, they weren't okay! Post continues below.

In between all this, there were of course 29,402 celebrity beauty brand launches, some questionable skincare tutorials, 90s hair made a comeback, and we were blessed with a whole lot of dramatic hair colour transformations from every A-lister, ever.

ANYWAY, the point is that a lot of stuff happened in 2021, so we're going to look back at seven of the most ~memorable~ beauty moments of the year.

Gwyneth Paltrow using sunscreen as a highlighter...

Remember that time Gwynnie gave us all some extremely unhinged and 100 per cent dangerous advice in herVoguebeauty tutorial? Remember?

In case you have subconsciously removed it from your brain, theGoopguru basically shared her $900 'less is more' skincare routine with us - including the bit where she uses sunscreen as... highlighter.

In the clip, she dabbed it sparingly only on her nose and cheekbones, explaining how she's not too much of a head-to-toe SPF kinda gal, and she just likes to place it "where the sun really hits".

It was really fkn dumb. Like, super incorrect. And people were MAD. Especially dermatologists.

There's was also some good ol' fashion greenwashing thrown in there, too.

JLo gaslighting us into believing her skincare secret was olive oil...

Earlier this year Jennifer Lopez launched JLo Beauty™ and tried to make us believe her skin looks the way it does (flawless) because of olive oil and positive affirmations. ¯\_(ツ)_/¯

Approximately no one believed her, but goodness she tried.

In an interview withThe Daily Mail, she said: "I haven't ever had Botox to this day... I'm not that person. I don't have anything against people doing that; it's just not my thing. I'm more about a natural approach to skincare… but I want [my products] to work," she said.

Then there was this response to a comment that suggested she uses cosmetic injectables: "Sorry baby no I haven't ever used [Botox and fillers]. This is what I use I hope you enjoy. Also a joyful heart helps."

A... joyful heart.

Instead of invasive procedures, Lopez said olive oil was, "a secret I’ve used over the years because it really does work."

The whole thing was just really awkward and riddled with dismissiveness and superiority.

Because ageing gracefully isn't embarrassing - but neither are cosmetic procedures. And, olive oil doesn't do s**t.

Everyone on TikTok using lube as a primer.

This was a thing! And I tried it! And it was weird!

For a moment there was a LOT of lube on a lot of faces and no one knew why but we were DOING IT ANYWAY.

The hack basically involved people on TikTok replacing their usual (read: professional) primers with a bottle of lubricant - specifically Durex Play 2-in-1.

And look, I'm going to be honest - I was pretty surprised when I tried it. I was 100 per cent certain the texture of the lube would feel super sticky and gross on my skin - but it felt really nice? Kind of like a hydrating serum??

But then I tried to put foundation over the top and it went all patchy and pilled (If you want to read more about my very serious research, check it out here).

Ellen DeGeneres launching a skincare brand calledKindScience...

Ellen DeGeneres - the longtime talk show host - who announced the end of her show in the midst of a toxic workplace scandal - launched a skincare brand this year.

And ICYMI, she called it...KindScience.

Explaining the theme of name, Ellen said: 'We call it Kind Science because it is kind to animals, it is kind to your skin, it's kind to the planet, and it's kind to your wallet. So it's all kind.'

So much kind.

While on the one hand, it's a good thing to see Ellen making more space and visibility for women over 50 in beauty - on the other hand, I feel like it wasn’t the best choice of name. Or timing.

Still not over it.

Shay Mitchell sharing her 58-step skincare routine...

There was also that time when Shay Mitchell shared her 58-step skincare routine withVogue- and just watching it will give you hives.

Without going into all of the products she uses (because CBF), after slapping on a Shani Darden cleansing serum and using an ice roller, thePretty Little Liarsstar went on to apply a total of SIX face masks. All at once.

She applied two under her eyes and one on her forehead - before covering them with a full face mask and adding another one to her chin. Then, she put one more mask over her entire face, 'to keep everything untucked.'

Finally, she finished the masking process with a 24-karat boob mask. All up, the masks cost her $233.

It was excessive AF, and the internet absolutely slammed her for being wasteful.

One person wrote: “She put all those masks on and wiped everything off and put on all those new moisturiser layers. The time... the effort.... the money.... Never seen a wasteful routine like this."

IDK if we’re being trolled or not, but honestly - it was approximately 54 steps too many.

Kristin Cavallari admitting she doesn't wash her beauty sponges because it makes them work better.

When Glamour interviewed Kristin Cavallari this year and asked for the one beauty rule she thought was total B.S., she said washing "beauty blender face sponges" - and honestly she's all of us. But, like, don't tell people you don't do it, right?

She said "Obviously we're supposed to wash those frequently, but I don't really wash mine that often because I actually think that when it's not clean, it helps blend better. Maybe that's disgusting, but…”

I feel like the only reason they would blend better is because they’re probably caked with old foundation? Likely.

Either way, experts obviously say you’re
