Another of Senior Shopping Writer Tessa Flores’ personal reviews made a splash this month, after she wrote about this Medicube plumping stick, which she called “the closest thing to facial filler I’ll ever get.” The K-beauty multi-balm stick contains 5% Volufiline, which dermatologists previously told HuffPost can create a temporary appearance akin to filler. Grab it for 40% off.

“I really like to apply this not just under the eyes, but also along my upper cheeks to help promote a more contoured look and boost the volume that I’ve lost with age and weight loss, as well as on my lips to minimize the appearance of lines and create a plumping effect,” Flores wrote.

She also said, “I really like that the texture isn’t heavy or balmy at all, but instead feels really silky, lightweight and melts into the skin. This means I feel better about swiping this on my face throughout the day or whenever I need a touch of hydration, without worrying that it’s going to completely remove my makeup or make me look greasy. It’s become my new pal on flights as well to help stave off that drying cabin air.”

Whether you’ve got OK lashes that only need a slight lift and some color or you’re a mature cutie with lashes a little sparser than they once were — we’ve found a discounted treat for you today: The top-selling, highly-rated Lash Idôle lifting and volumizing mascara from Lancôme is back and currently 40% off! Deemed “the best mascara that I have ever gotten,” the best replacement for people’s discontinued go-tos and even “magical” for transforming “even my small, 60-year-old lashes,” it’s a beloved product that’ll earn a spot in your daily routine! “Goes on smoothly,” user me q. writes in a review. “I am 68 years old and my lashes look like lashes of a 20-year-old. I won’t be using anything else.”

This low-maintenance shower cleaner promises to require no scrubbing at all — just spray it on dingy, scummy shower walls, let sit overnight and then rinse to get rid of built-up soap, grime, stains and body oils. It’s bleach-free and safe for most surfaces, including glass, porcelain, sandstone and tile, though it’s not recommended for use on natural marble. Grab it for 19% off.

If you desire pristine white chompers — and really, who doesn’t? — you’ll want to jump on this deal pronto. Both my hygienist and dentist recommended that I use Crest’s 3D White Brilliance mouthwash for real whitening results. The dentist specifically recommended that I use it at night without rinsing it out so that the whitening agents can continue working while I sleep. I tried it, saw the results and haven’t looked back since. When I buy a two-pack, I typically don’t need one until a full year out. This means I probably won’t be buying this for the first Prime Day of 2027, because I won’t be due for a re-up until October!

Crepey skin, where? This 5-in-1 oil is packed with all of the ingredients you’ll love to achieve peak softness this fall and winter including jojoba oil, squalane, bakuchiol, collagen peptides and vitamin E. Bonus?

Promising review: “I love this oil it’s not greasy SMELLS SO GOOD!!!! Makes my skin look and feel amazing. The whole super serum line is amazing I use the serum body wash lotion and oil. My skin looks bright and glowy it feels amazingly soft as well” — Jezel

These wide-leg sweats are more versatile than you might think. They’re a dream for lounging around the house, but when it’s time to head out to school pickup or to run errands, you can pair them with cute flats and a button-down just as easily. These pants are made with a cotton-poly blend that feels soft and comfortable against the skin and are designed to keep you warm on chilly days. One reviewer said, “If you are on the fence about them, get them because you won’t be disappointed!” As a bonus, they also haven’t been this cheap since January.

Come for the adorable packaging but stay for the actually-effective stain-fighting power of this "magical" spray. The water-based formula promises to eradicate some of the greatest offenders — including grease and coffee — and is free of phosphates, sulfates, perfumes and dyes.

Multibalms are the way of skin care's future, and beloved K-beauty brand Medicube released this plumping pink stick packed with a powerful combo of PDRN, retinol, NAD, peptides and collagen for a bouncy and hydrated complexion.

“I really like to apply this not just under the eyes,” Flores writes . “But also along my upper cheeks to help promote a more contoured look and boost the volume that I’ve lost with age and weight loss, as well as on my lips to minimize the appearance of lines and create a plumping effect.”

If you suffer from the annoyance of frequent dandruff, consider grabbing a bottle of Nizoral while it’s on sale for Big Deal Days. It’s a clinically proven formula that’ll help prevent scabbing and flaking and control fungal growth. You won’t find a better deal at your local pharmacy!

There’s nothing as eternally chic as a cardigan, and this one from Amazon looks strikingly similar to those of J.Crew, Quince, and Reformation fame. Made from a soft knit, lightwieght fabric, it has a classic crewneck and slightly cropped fit. It comes in sizes 2XS-2XL and several colors, though not all colors will be on sale for Prime Day.

Shopping writer Erica Kam and her dad are both big fans of Premier Protein shakes — they're ready-made and don't require any mixing or blending, which makes it so much easier to just grab them and go. They also don't taste powdery or grainy, and nearly every flavor she’s tried has been a winner. This is even cheaper than they were during June’s Prime Day sale.

HuffPost Shopping contributor Michelle Rostamian swears by this leave-in conditioner for keeping her dry hair in good shape. It prevents breakage and frizz, and contains keratin, argan oil and more hair-nourishing ingredients.

This face mask is a popular K-beauty buy, giving your skin a bouncy texture and soothing those pores. Let these skin-plumping sheets absorb into your face for up to four hours, or just wear it overnight, and you’ll wake up feeling fresher.

Skin care enthusiasts swear that microneedling — the process of puncturing your skin with tiny needles to create micro-tears that stimulate collagen production and boost skin care absorption — is the ultimate key to smoother, evenly-toned skin. Still, as promising as those before-and-after photos may look, it can be expensive, invasive and downright scary.

With that considered, we found a product that may offer a gentler at-home solution for the trend, and reviewers say it “helped smooth all the bumpy patches” and make their skin “even and super soft and supple,” only after a few uses. Korean beauty brand Medicube has its tingly, microneedle-like Zero Exosome Shot 2,000 on sale right now on Amazon, and better yet, it’s 40% off. A sub-$12 beauty product is a tiny risk for an attempt at smoother, evenly textured skin.

If you’re looking for some retinal (not retinol) to add to your skin care routine, consider grabbing this bottle from Meditherapy. This 5-ounce serum is safe to use on your face and body, and several reviewers describe it as a “lifesaver” for acne and diminishing wrinkles.

Batteries are always a great thing to have on hand, especially if the weather is prone to knocking the power out in your area. Grab this 32-pack of AA batteries and never worry about a dead flashlight (or remote control) ever again.

These Medicube pads are designed to help exfoliate, balance and brighten skin while reducing oil production, minimizing breakouts and refining the look of pores. They are formulated with powerful alpha and beta hydroxy acids like white willow bark, vitamin C and calming botanical extracts like lavender to soothe skin.

This three-pack of Colgate Optic White toothpaste is nearly 30% off for Big Deal Days, and it’s said to remove 15-year-old deep-set stains with consistent use. Reviewers seem to agree with this claim, more or less, as one says: “I’ve been using it for years and it’s slowly made my teeth whiter, despite all the tea and coffee I drink!”

If you’ve ever dealt with “crepey” skin — or skin resembling crepe paper in its dry, wrinkled, thin appearance, this is for you. This fragrance-free, lightweight lotion works to keep skin smooth and moisturized, thanks to a unique smoothing concentrate that features protective antioxidants, omega-3 fatty acids, and powerful botanicals. It gives you a nourishing, replenishing boost while keeping your skin feeling elastic and bouncy, and experts have previously recommended using products with nourishing vitamins and antioxidants to help restore skin's moisture and help to prevent and reduce crepiness.

This foaming dish spray works superbly and most professional cleaners will tell you that you can use it to clean more than dishes. We love it so much here at HuffPost that we even gave it a HuffPost Shopping Award. (108,033 Amazon shoppers have also helped the product earn a 4.8-star rating.) Grab this household staple plus refills in this sale and you probably won't need to buy dish soap again for the rest of 2026. I know I will!

If you don’t have a Costco membership, this deal might entice you: 62 dishwashing tablets for just $14. With that math, you’ve basically got a membership to a wholesale club, and a few months’ worth of clean dishes.

Skin care is about more than the skin on your face, a truth HuffPost readers clearly recognized judging by their continued interest in this Medix 5.5 retinol body lotion. The lotion contains retinol and ferulic acid to moisturize and reduce the appearance of wrinkles and crepey skin. Reviewers have called it an "exceptional skin care discovery," saying they could "genuinely feel a difference" after a month of use.

If you've got holes in your undies right now (I won't tell), please do yourself a favor and freshen up that drawer of yours. This six-pack of boxer briefs from Hanes is reason enough, as it's nearly 30% off right now. They're the perfect balance between the tighty-whities and the looser briefs. Get them in the most basic colors for any occasion: black and gray. However, they also come in bolder choices if you prefer a little more personality under your pants. They come in sizes S-3XL.
