We’ve sifted through Amazon’s beauty section for under-the-radar products on sale and have the reviews to back up the hype.

Over 50-year-old celebrities like Kristin Chenoweth have been relying on it to give their skin a healthy glow for decades. Others in the spotlight, from reality royalty like the Kardashians (especially Kim) to actual royalty like Kate Middleton and Meghan Markle, also credit this product with keeping their skin free of stretch marks.

One of 36,000 reviewers calls Bio-Oil freaking amazing. "I use this stuff ALL OVER my body," she wrote. "It's great — it's lightweight so I don't feel like I just took a bath in a deep fryer. I can use it on my face without worrying about breaking out (like I often do when using coconut oil), and it leaves my skin soft and glowing ... It sinks in fast, so I don't leave greasy fingerprints everywhere. I can't stress enough how great this stuff is."

Soft Touch

Soft Touch Foot Peel Mask

$20

This foot peel mask comes in a set of two. They're formulated with a blend of botanical extracts to slough away the dead skin on your feet and repair cracked heels.

$20 at Amazon

Wearing flip-flops and sandals in the summer can wreak havoc on your feet, but the cold dry weather of winter doesn't do your feet any favors either. Fortunately, this set of feet-peeling masks can help get that soft skin back, no matter what the season is. You slip these on your feet for an hour and in two weeks, the dead skin flakes away to reveal the supple feet you've been missing. There are more than 13,000 rave reviewers who get behind this foot-saving treatment.

"Wow," shared one shocked shopper. "I'm always skeptical when I purchase health/beauty products like this and usually end up with lackluster results. But with this I'm impressed! I can't decide if I'm grossed out or amused but this product is worth more than any pedicure you can receive if you want to get rid of dead skin. I had a special event the following week so made sure I soaked my feet every day to hurry the peeling process. Used the foot mask on a Sunday; no peeling on Monday; minimal peeling on Tuesday and then it was a poppin' peelin' party on Wednesday. Buy it, people!"

Medix 5.5

Medix Retinol Body Lotion

$19$25Save $6

This cream employs the critical anti-aging ingredient retinol (vitamin A) and the antioxidant ferulic acid to revive skin that's getting a bit crepey.

$19 at Amazon

From a young age, we're programmed to believe that unless we hide from the sun, we're destined for saggy, wrinkled skin. The conventional advice is to wear big hats in summer, and stay indoors midday — protect and cover. Turns out it's still possible to have beautiful skin as you mature. More than 19,000 Amazon shoppers credit a certain lotion with restoring elasticity: Medix 5.5 Retinol Cream with Ferulic Acid Anti-Sagging Treatment.

"I purchased [this] retinol lotion to help with crepey skin on my stomach after losing 103 pounds," shared a convert. "It drastically reduced how wrinkly my stomach looks in like a week and a half. This won't get rid of my excess skin, but it definitely makes it look firmer and less ugly."

Amazon

Formulated specifically for post-acne skin, this retinol serum promises to refine skin texture over time. It also claims to minimize the appearance of pores. With an army of nearly 33,000 five-star fans, this is a product worth checking out.

"I suffered from terrible acne for my entire adult life and after undergoing a very harsh treatment with my dermatologist, the acne disappeared but I was left with deep scars, dry skin (it was oily before), ultra sensitivity to pretty much anything and dermatitis," reported an acne sufferer. "I tried a bunch of products and nothing helped, most things left me with a pretty nasty rash, even stuff that was designed for sensitive skin. I decided to make the switch to Cerave and now I couldn't be happier with the results! I made every step of my routine a Cerave product and I can really see the results! I was really depressed because of my skin but I finally got my confidence back!"

$17$25Save $8

With over 50,000 rave reviews from verified shoppers, this serum has a massive fan base — many of whom rave about how hydrated and bright their skin feels after use. 

$17 at Amazon

A serum loaded with snail mucin — aka snail excretion or slime — has been making the rounds on TikTok and in Amazon shoppers' carts, and for good reason. CosRx Snail Mucin Repairing Essence, made with 96.3% snail secretion filtrate, may sound bizarre and even medieval, but loads of women rave that it helps improve dullness and dryness.

"At 60 years old, I have tried a lot of products for skin care," shared one former skeptic. "I have not been more impressed with any product ... it has a light scent, you don't need to use a lot. My bottle is half gone after a few months. It has completely erased some old scars from some facial surgery. My skin is much more toned and wrinkles are minimized!"

On top of all that, it contains sunscreen to protect your skin from harmful UV rays. More than 11,000 five-star reviewers are already enjoying the benefits. One shopper liked it so much, he stole a tube from his girlfriend after a scuba diving trip.

"I don't even notice I put anything on, not even that ugly white residue look from normal sunblock," he shared. "It even gave me a bit more of an even complexion. Of course, I am not giving her the satisfaction of knowing how much I like it at this point but I am definitely not complaining about it which I know she can see right through. However, at the end of a full day on the beach and realizing how well it worked I cave and acknowledge her undeniable wisdom. At the end of the trip I snag the tube with a full on backstory ready of how it mysteriously ended up in my bag. This is my second tube. The end."
