As beauty editors, we’re fascinated with skin care products that claim to be anti-aging. Yet in our years of testing, we’ve noticed that many brands in this category over-promise and under-deliver.
So, we’re always on the lookout for solutions for our readers. We sought a science-backed brand that effectively nourishes your skin, minimizes wrinkles, and signs of aging, all without resorting to costly and invasive treatments.
What We Were Looking For
Let’s be real — most “anti-aging” skincare doesn’t deliver. We wanted something better: a science-backed product that actually helps skin age healthfully, without costing more than a spa weekend.

OneSkin Overview
What won us over with OneSkin? Transparency. They publish their research, name their peptide, and even share citations. OS-01 isn’t just a marketing phrase — it’s a patented peptide developed by a team of female PhDs over 5+ years.
Their mission: target senescent cells — the “zombie” cells that accelerate aging, degrade collagen, and weaken your skin barrier.
You can access their scientific publications directly from their website, which was a huge green light for us in making sure they weren’t just another brand touting pseudoscience. For us, this brand stands out for its science-forward approach, and we knew we had to test out its products to see if the peptide lives up to the hype.
OneSkin’s OS-01 powered cult favorite, OS-01 FACE, is fragrance-free and has been evaluated by SkinSAFE to be safe for sensitive skin — it’s an effective, non-invasive, gentle solution for all skin types.
OneSkin offers three Topical Supplements, all powered by the OS-01 peptide, that promote lasting changes to support skin health. The findings of a 12-week clinical study evaluating OS-01 FACE, performed by a third-party Contract Research Organization, show that:
Clinical Results (OS-01 FACE)
- Skin barrier improved by 15%*
- 90% reported better skin elasticity**
- 87% saw fewer wrinkles and fine lines**
- 100% saw improved smoothness and appearance**
Pair OS-01 FACE with:
- PREP Cleanser – clears away what blocks absorption
- OS-01 EYE – visibly firms delicate eye-area skin
Augustinus Bader Overview
Augustinus Bader products are luxe, no doubt. But navigating their site was…a lot. With over 10 different facial products and limited transparency around their “TFC8” complex, we were left wondering: What exactly am I buying?
Yes, it works — the Cream delivered:
- Fine lines and wrinkles were reduced by 32.74% after 4 weeks****
- Skin looked 52.94% younger after using this product for 4 weeks****
- 87% agree skin looks regenerated*****
- 87% agree skin is left with a youthful, healthy, radiant glow*****
- 71% agree skin looks and feels like it is regenerating faster than ever*****
But…at $290 for 50ml, it’s almost triple the price of OneSkin — and we still don’t fully understand how it works. That’s not great when we’re investing in long-term skincare.
Final Verdict: OneSkin Is Our Winner
Between the science, simplicity, and value, OneSkin is the clear winner. It’s backed by peer-reviewed research, has visible results, and doesn’t require a chemistry degree (or a second mortgage) to use.
If you want visibly healthier, smoother, more resilient skin — without breaking the bank — OneSkin is the move.
