The $49 Skin Serum Costco Shoppers Can’t Find Anymore — Here’s Why
Fact Checked May 2025 by Sarah Sachler

For months, it was one of the fastest-selling skincare products in Costco’s beauty aisle—flying off shelves four separate times before quietly disappearing.
Customers were raving about the $49 serum that made their skin feel smoother, firmer, and more hydrated—without harsh ingredients or complicated routines. But now? It’s nowhere to be found in-store or online.
So what happened?
🔍 The Serum That Quietly Went Viral Inside Costco
...and why you can no longer buy it there

Costco isn’t known for flashy skincare — but members who know what to look for often discover clinical-grade products hidden between the household goods and Kirkland jeans.
One of those hidden gems was a peptide + vitamin C serum with a cult-like following among women 45 and older. Priced at just $49, it was a fraction of the cost of department store serums that often use the same core ingredients.
“It felt like finding a $150 serum in a warehouse club,” one shopper said. “I saw changes in my skin in just two weeks—and then I couldn’t find it again.”
🚫 Why It’s No Longer Available at Costco
According to industry insiders, the brand behind the serum—Dermacyl—chose not to renew its bulk retail distribution deal earlier this year.
Why? One source close to the company cited quality control concerns with how the product was being stored and handled during bulk shipping. The serum’s formula uses sensitive active ingredients (like stabilized Vitamin C and peptides) that can lose potency if exposed to prolonged heat or UV light—conditions that are hard to avoid in large warehouses or long-distance freight.
Instead, the company has shifted to direct distribution to ensure ingredient integrity and freshness.
✨ What Makes Dermacyl Fly Off The Shelves and Sell Out 4x?

Consulting with cosmetic chemists, dermatologists, and beauty experts from all over this great country, we researched what worked and what didn’t work in skincare. We sought to create an all-in-one product that could replace a cabinet full of skincare creams, lotions, and serums. First, we selected a unique Vitamin C extract that is shown in studies to produce far better results than standard Vitamin C.
The serum (now sold as Dermacyl Peptide-C Radiance Serum) was developed to meet the needs of maturing skin without relying on retinol, acids, or harsh exfoliants.
Combines clinical-grade peptides to support collagen renewal
Includes stabilized Vitamin C to brighten and even tone
Lightweight, fast-absorbing, and ideal for daily use—even for sensitive skin
Shoppers who bought it at Costco said they were shocked to find something so effective and affordable.
💬 Where Can You Still Get It?
Although it’s no longer available through Costco, the same original formula is now available directly from the brand’s website—with smaller-batch production and tighter control over shipping and shelf life.
