I test beauty products for a living, which means it's literally my job to know what's worth your money and what's just clever marketing in pretty packaging.

And let's be real: keeping up with beauty trends can do some serious damage to your wallet. It feels like every other day, there's a new serum going viral on TikTok, a face mask being called a 'game-changer' or a revolutionary skincare tool you desperately need to own.

Even if you're smart with your spending, all those "little" purchases can quickly add up. Which is exactly why Amazon Prime Day is one of my favourite times of the year.

Watch: Kelly and Sarah Marie discuss their 'desert island' beauty products on You Beauty. Post continues below.

You can snap up Dyson hair tools with hundreds slashed off, grab Olaplex for a fraction of the usual price and… if you thought K-beauty products were already affordable, just wait. During Prime Day, they're… even cheaper.

Oh, just a note: You do need to be an Amazon Prime member to take advantage of all the savings, which will set you back a mere $9.99 a month, or $79 a year. This also comes with free and fast delivery, access to Prime Video, Prime Music and Prime Reading. Or, you can also sign up for a free 30-day trial right here, get access to all the deals and cancel whenever. No strings attached. Just glorious discounts.

(PS. I highly recommend checking out this in-depth explainer on everything you need to know about the sales.)

Now that's settled, it's time to get shopping! From cult skincare buys to viral hair tools and underrated gems you've probably never heard of, I've combed through the chaos to bring you the 30 best beauty deals I'll personally be shopping — and you might want to as well.
