Real Skin, Real Results: The Brightening Serum that Actually Does the Work

Real Skin, Real Results: The Brightening Serum that Actually Does the Work

At 28N, we’ve always believed that great skin starts with transparency—about ingredients, about results, and about the process. So when it came to our new Brightening Serum, we didn’t just want to say it worked. We wanted proof. The kind that holds up under a microscope (literally).


So, we sent our formula to an independent lab for a full in vivo clinical trial—four weeks, eight women, a regimen that mirrored real-life use (twice a day after cleansing), and professional-grade skin imaging to track the changes. Here’s what happened.


The Setup: Science, but Make It Skincare

The test was conducted on women aged 20 to 55, across four time points: day 0, 7, 14, and 28. The tools used? High-tech devices like VisioFace 1000D, C-Cube, and Mexameter MX18—machines that measure things your iPhone camera could only dream of. We tested two versions: our Brightening Serum solo, and paired with our Essence Toner (because we love a power couple).


The Results: Small Numbers, Big Glow-Up

Let’s break it down.


By day 28, when used with our Essence Toner, the Brightening Serum delivered:


  • +2.96% ITA (Individual Typology Angle) — basically, a fancy way of measuring skin brightness
  • -15.77% melanin — yes, you read that right: less pigmentation
  • +20.29% gloss — aka that healthy, dewy glow
  • -20.54% texture roughness — smoother skin, visibly and tangibly
  • -8.58% redness — calmer, more even-toned skin

 

Even the serum on its own made major moves: melanin down by nearly 13%, glow up by almost 17%, texture and redness reduced across the board.


So, What Does That Look Like?

Imagine that “you” after a holiday—not the jetlagged one, the one that returns luminous and smug. That’s the vibe. And if you’re more of a see-it-to-believe-it person, the images from the study speak for themselves. Skin looks calmer. Brighter. Less inflamed. Less…everything you’re trying to blur with concealer.

 

The Takeaway: Clinical-Grade Brightening, Without the Clinical Feel

It’s one thing to hear a product “brightens.” It’s another to watch it actually reduce pigmentation, smooth skin texture, and tone down redness—in under a month.

 

So if you’re wondering whether the Brightening Serum is just another glowy promise in a pretty bottle, now you know: it’s clinically proven to deliver. (And yes, it still looks cute on your vanity.)
