90% Bioactive Ingredients
Our ReGenerative Serum has over 90% bioactive compounds, like youth-messaging peptides, plant exosomes, and Consortia Factors® for maximum impact with minimal filler.
Infused with Consortia Factors®, including UCFxF, exosomes, and youth-messaging peptides, it visibly lifts, smooths, and renews while training skin to behave like it did in its prime. Each drop whispers in the language of renewal, reawakening skin’s memory from the inside out through intuitive, layered care.
The Stem Company rewrote the story of aging skin. We set the bar higher.
While others test on younger skin, we proved results on women with an average age of 62. Our independent clinical study delivered visible, measurable results — in just 8 weeks.
Why it works:
Our proprietary Consortia Factors® technology retrains skin to revive, renew, and remember youthful behavior. This bio-intelligent approach is what makes fast results possible — even in older skin.
The results speak for themselves.
Developed by Dr. Nathan Newman, MD, pioneer in stem cell science. Backed by decades of clinical research in regenerative medicine, designed to restore how your skin behaves, not just how it looks.
The Stem Company delivers intelligent care that feels gentle yet performs powerfully, making effective self-care both approachable and reliable.

The Secret Behind Stem Cell Skincare
The Stem Company's approach to skincare is about decoding how stem cells communicate.
By studying regenerative medicine and dermatological biology, our team developed Consortia Factors®—a proprietary system that mimics the language skin uses
to regenerate.
No guesswork. Just smart science.
Excellent serum!
I started last week when I received it. I only used the serum in the morning and at night on clean skin. The serum went on smoothly and I did not use any other moisturizer or creams. My skin was hydrated overnight, and I applied again next morning. In the next couple of days, my skin stayed smooth and hydrated. I noticed my face appeared brighter and I'm really pleased using this serum without anything else.
Incredible serum
I’m obsessed! Works wonders leaving skin glowy and so soft!
Actually works!
This is one of the only products where I saw results within a week. I've used tons of stuff but this calmed my skin down so much and because of that, I've ordered more products. If you have any redness, this really helps.
This is a fantastic product!
I’ve been using the serum for about six months, and the results are quite positive. My skin is more glowing, the appearance of wrinkles is diminished, and the discoloration is lessened. I’m definitely going to continue and will try the other Stem products as well.
Amazing results
My skin has never looked better. Lightweight, fast results. 10/10!
