The Best Beauty Sales of the Week Include My Favorite Acne-Fighting Serum and Microcurrent Device

This serum from famed plastic surgeon Dr. Diamond was named Marie Claire's Best Serum Overall of 2025, and it's not hard to understand why. The dermatologist-beloved serum uses bioengineered human identical growth factors to stimulate your skin's ability to repair itself and promote firmer, more lifted looking skin.

The first time I tried this microcurrent facial toning device, I looked in the mirror and unironically said, “Oh wow, it's like I have a new face.” Needless to say, this little tool lives up to its name. Use it properly, and it'll make your entire face look lifted and, dare I say, brand new, in minutes.

Sunscreen is one of the only beauty products I wear every single day (other than my usual skincare routine), and this one from Supergoop! is what I go to when I don't want to worry about potential white cast or pilling. And thanks to the Dermstore sale, this jumbo-sized bottle gets you the most bang for your buck.

I have acne-prone skin with never-ending redness and uneven tone, so I'm always on the hunt for a good product with azelaic acid, which can help calm redness and fight discoloration without irritating the skin. This formula from Allies of Skin is my absolute favorite.

As I get older, I've noticed that the trick to a good makeup look is a good, hydrated under-eye. This RMS Beauty concealer gives coverage without drying out my skin, leaving my under-eyes smooth instead of cakey. I also love that it can be sheered out or layered for added coverage.

If you're a regular at your local nail salon, odds are your cuticles and nails could use some TLC. Enter: ISDIN's Si-Nails Strengthening Nail Serum. The formula helps boost keratin production, which in turn leads to stronger, healthier looking nails. Plus the pen packaging makes it easy to use on the go.

The Revlon Hot Air Brush is a classic for a reason. This updated version is just as good as the viral original if you're looking for a 2-in-1 tool that'll dry your hair and give you the voluminous blowout of your dreams.

When deciding what hair tool to invest in, the first thing you have to ask yourself is: “Do I want straight hair or curly hair?” To which T3 would say, “Why not both?” This Curling Straightener is a 2-in-1 iron so you don't have to choose. Talk about a win-win.

Yes, Dyson hair tools are included in Ulta's HAIR20 promotion, and, yes, they are worth the hype. Granted, even with the sale, a Dyson Airwrap is a serious investment, so if you're still unsure, make sure to check out our Dyson Airwrap I.D. review.

If you're looking for a more simple hairdryer than the airwrap, but you still want salon-quality, then the Shark Speedstyle Pro Flex hair dryer system is your best bet. It's foldable design makes it easy to store and it comes with four attachments, so you can style your hair how you want it.

Made specifically for those with low porosity, curly, or coily hair, Pattern's Hair Steamer is a great tool if you want to get the most out of your hydrating hair products, especially conditioners.

I don't know what it is about hair curlers, but I can never get the angle or direction quite right. More often than not, I', left with a mop of mis-matched ringlets—not a good look. So when I learned that automatic rotating curling irons like this one from T3 existed, it was a game changer. You'll never have to question yourself again, just let the rotating curler do the work!
