50% off a Sunday Riley exfoliating serum…
This is the OG lactic acid exfoliating serum. It’s gentle enough to use every day for most skin types, and it visibly plumps, hydrates, and brightens your skin. It can even fade pesky discoloration. (Originally $85, Now $42.50)

30% off a detangling mist that smells like sugar cookies…
One shopping editor swears by this milk_shake mist for detangling her long hair. It also acts as a comprehensive leave-in conditioner, so you’ll have smoother, softer hair throughout the day, even if you air-dry it. We also love the sweet-but-not-sickly fragrance. (Originally $28, Now $19.60)

30% off the cult-favorite Laneige Lip Sleeping Mask…
Put it on right before bed and wake up to smooth, supple lips in the morning. It’s as simple as that. Plus, you can wear it during the day for a glossy, healthy look. The new Pumpkin Pie scent is irresistible for this time of year. (Originally $24, Now $16.80)

20% off the Medicube Age-R Booster Pro…
Hailey Bieber uses this in between skincare steps to boost absorption. If you’re not already convinced, we’ve tried it and can confirm it made our skin look glowier immediately. (Originally $210, Now $175)

20% off the Daybird 4-in-1 Serum Skin Tint…
This is the multitasking product we can’t stop wearing every day. It actually improves our skin as we wear it, thanks to niacinamide that hydrates and bisabolol that reduces inflammation. At the same time, zinc oxide protects against blue light and harsh rays. (Originally $39.50, Now $31.60)

30% off a Tower28 hydrating serum…
Like our favorite Tower28 face spray, this serum has hypochlorous acid to soothe, reinforce the skin’s barrier, and reduce redness. It’s also safe for acne-prone skin, since hypochlorous acid is also antibacterial. (Originally $34, Now $23.80)

30% off an Origins eye cream…
This bestselling eye cream comes in two tints — depending on if your skin is warm- or cool-toned — that conceal dark circles. It also hydrates and reduces puffiness, thanks to a combination of caffeine, ginseng, and vitamin C. (Originally $39, Now $27.30)

Up to 40% off an Oral-B electric toothbrush…
We’re avid electric toothbrush users. While they’re definitely an investment, we worry less when we visit the dentist.

24% off a big box of face towels...
If you keep breaking out, you might need to start using these biobased, single-use face towels to dry your face instead of your dirty bath towel.
