Plexaderm Reviews: An effective dark circle eraser?

We’ll break down the pros and cons to help you decide if Plexaderm provides the under-eye skincare that you need.

Last Updated: Mar 9, 2022
Plexaderm Reviews

Whether they’ve popped up after a poor nights’ sleep, allergies, or with age, dark circles can be frustrating. There are dozens of reasons that they happen, and yet somehow, it seems like no matter what you do, they just won’t go away. They aren’t dangerous, but looking like you haven’t slept in weeks first thing in the morning after a relaxing nights’ sleep can get old fast.

Plexaderm offers an under-eye skincare product advertised to rehydrate and lighten dark circles to near-invisibility. But when so many skincare products flaunt those same perks and don’t measure up, it can be challenging to figure out what you can trust. We investigated Plexaderm’s promises to see if they provide effective lightening and brightening, so you can decide whether or not the product is worth your time and money.

Review Summary


  • Scientifically proven to lift under-eye bags, dark circles, and wrinkles up to 80%
  • Near-instant results
  • Strong privacy measures at check-out
  • Six-application trial size available at a low cost if you’re not ready to commit
  • 30-day return guarantee, whether or not you’ve opened the product


  • No permanent results or changes
  • Must pay for shipping on all returns
  • Only ships to the US and Canada
  • Estimated shipping times can be a little slow

Bottom line

If you need a quick fix to boost tired-looking eyes, Plexaderm is going to be your best bet on the market. However, their results aren’t permanent – the silica-based formula forms a temporary tightening layer that goes away once Plexaderm is washed off at night. While it isn’t the cheapest skincare serum on the market, it’s definitely one of the most effective and best at what it does.

Why you should trust us

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

We extensively test each health service we review. We try our best to give you an unbiased exploration of at-home health services, free of marketing jargon or gimmicks. We evaluate products and services based on our adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren’t part of our job, and would we recommend it to family and friends?

Additionally, like all health-related content on this website, this review of Plexaderm was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

What is Plexaderm?

Plexaderm is the pride of Sheer Science’s skincare collection. Founded in 2015, the company focuses on making products that help you look and feel better, including teeth whitening, makeup, hair care, and, of course, skincare products. Sheer Science also donates to and partners with several local charities, so you can feel good knowing that every Plexaderm purchase helps those in need.

Plexaderm – formally known as Plexaderm Rapid Reduction Serum – is a serum designed to reduce under-eye bags, dark circles, and wrinkles. This as-seen-on-TV product tightens and smooths your skin for a more youthful look.

Sheer Science has won two awards for Plexaderm: the Golden Bridge Award for Best New Product (Gold) in 2018 and the Most Innovative Product of the Year (Silver) from the Best in Biz Awards. These are competitive awards and additional signals that Plexaderm’s promises are true.

How does Plexaderm work?

Plexaderm uses silicate minerals from shale clay to create a temporary tightening layer on your skin. Over time, the skin around your eyes loosens, creating sagging skin, noticeable veins, and more prominent subdermal fat. By re-tightening the skin in problem areas and helping the body produce more collagen, Plexaderm helps your skin bounce back. Shale clay is a widespread ingredient in high-quality face masks for that same reason, using safe and effective minerals.

Sheer Science has many before and after pictures on their site of real users’ results, bragging that each happened in about 10 minutes. This short timestamp is accurate from our appraisal, but Plexaderm doesn’t create permanent results. The serum sits on top of the skin, pulling it taut and smoothing it for a youthful shine, but it doesn’t penetrate your skin for a permanent change. If you like your results with Plexaderm, you’ll need to continue using it every day. Think of it more like tape than a filler.

Scientific study

Sheer Science performed their own study in early 2019 to see if Plexaderm actually works or if its effects are marginal. While it’s a more investigative study than something you’d see published in an academic journal, it still provides some valuable information, albeit information you should take with a grain of salt. This study was part survey and part visual analysis.

The visual analysis, using a VISIA Complexion Analysis System (a high-tech standard piece of technology in dermatology), showed huge improvements across several measures in people who used Plexaderm:

  • Smile lines (74%)
  • Undereye bags (80%)
  • Dark circles (80%)
  • Eye-area wrinkles and Crow’s feet (81%)
  • Depth of forehead lines (85%)

The other half of the study was a survey that asked about their feelings and overall satisfaction with Plexaderm. The survey was given to people in-lab after applying Plexaderm and completing their visual analysis. Within this population, the results were overwhelmingly positive: everyone said that the serum met or exceeded their expectations, with less noticeable wrinkles, a smoother and more even texture, and less noticeable dark circles. Two-thirds of those who responded said they felt at least ten years younger.

Rapid Reduction Serum and other products

Plexaderm Rapid Reduction Serum

Sheer Science offers a unique trial method if you’re curious about Plexaderm but aren’t ready to commit to a full bottle. This trial pack offers six applications’ worth of Plexaderm in a blister pack. Each pod contains 0.3mL of Plexaderm, which is a good reference to keep in mind to show exactly how much one dose looks like. A trial pack of Plexaderm costs $14.95.

The standard size bottle of Plexaderm contains 30 applications’ worth of serum at 5mL. You can get this in multiple size packs from Sheer Science’s website:

  • One bottle ($59.95)
  • Three bottles ($119.90)
  • Six bottles ($239.80)

Concerned about using too much and wasting product? You can order a full 30 days’ worth of Plexaderm in a blister pack box at no additional cost. If you know you like it, the blister pack box also comes in packs of three and six.

Plexaderm’s website doesn’t include everything you can find on Sheer Science’s site, so we recommend heading over there to place your order. However, for convenience’s sake, they offer the six-day trial pack and one- and three-bottle packs through the Plexaderm site.

Sheer Science does not offer auto-shipments or subscription services, so you’ll need to manually reorder Plexaderm when you run out.

Other Plexaderm products

Is Plexaderm a good value?

When it comes to your skin, it’s essential to know you’re putting safe, effective products on your largest organ. Plexaderm offers safe ingredients – no major side effects have been reported to date – at a moderate cost. Skincare can be notoriously expensive, and with the skincare industry projected to crest $200 billion by 2026, you have no shortage of options. Even with alternative serums ranging from $20 to $250, Plexaderm cuts through the middle of the market with frequent sales and buy-two-get-one deals on multi-bottle packs.

Plexaderm is also a product that seems to work consistently across populations. It’s not easy to find a serum that works for everyone, but Plexaderm stands out with its near-universal results. While you may find variation in how well it works for you, with up to 80% removal of dark circles, wrinkles, and under-eye bags almost immediately, it’s hard to say no to such a good deal.


Plexaderm always ships free to the United States (excluding Alaska and Hawaii), but there is a variable charge based on package size for international shipping to Canada. Orders coming to Alaska and Hawaii have to pay shipping and processing fees.

Most orders are shipped in one to two business days, but if you order before noon Eastern Time, Plexaderm will ship same-day. All packages arrive in another five to seven days. If you want to expedite your order for an additional fee, your Plexaderm will arrive in two to three business days instead.

Return policy

Plexaderm has a forgiving return policy. Anything, used or unused, that you don’t like or cannot use can be returned up to 30 days after purchase. You’ll need to call customer service first to get your return rolling, and be sure to include a slip with your name, order confirmation number, and reason for the request in the box. All refunds are processed within ten days.

Sheer Science won’t cover the cost of shipping on returned merchandise, so be ready to pay out-of-pocket to return your Plexaderm if it doesn’t work out.

Getting started with Plexaderm

Ordering is easy – you can pick up your serum from the Plexaderm website or Sheer Science’s online catalog. We’d caution you against using Amazon, eBay, or other third-party sites, as there has recently been a spike in counterfeit Plexaderm products that don’t work. When ordering from Plexaderm or Sheer Science’s website, you can pay with any major credit card or PayPal.

Once your Plexaderm has arrived, all you’ll have to do is apply a layer to areas of interest (under-eye, unless you have wrinkles in other places like smile lines you want to minimize). Your skin should be clean and dry, and if you’ve put on any other products, make sure that you wait at least 10 minutes before applying Plexaderm.

After applying Plexaderm, you can either wait for it to dry naturally for 5-10 minutes or use a blow dryer on the lowest setting to speed the drying process.

You can apply makeup after putting on Plexaderm, but Sheer Science recommends sticking with dry or powder-based makeup to avoid accidentally wiping it off.

How we evaluate health services and products

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service. For health-related products and services, we have five areas that we use for our evaluations, including:

Quality: How well does the company deliver its core service(s) and product(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telehealth services, is the quality of the service and/or product high enough that we would recommend it to loved ones without hesitation? If not, why not?

User-friendly: How intuitive and user-friendly is the service? Does the device/program/app/website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money’s worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure?

Customer support: Particularly in situations where ‘one size fits all’ doesn’t make sense, how well does the company help to make the service ideal for you?
