In the cosmetics world, the minimum standard is exactly that — a minimum. Products must be proven free of contamination and stable enough to sit on a shelf.
But Soke’s multi-peptide hydrogel technology is more advanced than typical creams or gels. To protect its integrity (and your skin), Soke invests in a much deeper level of testing. Every formula undergoes:
- third-party cosmetic safety assessments
- stability and stress testing
- ingredient-level toxicity reviews
- and human patch testing
This extra layer ensures that Soke masks deliver visible results with the same reliability you would expect from a clinical treatment.
Luxury is the experience. Integrity is the science behind it.
The Tests That Define the Soke Standard
Below is the science — explained simply, without skipping the important details.
USP <51> Preservative Challenge Test
How we make sure your mask stays fresh, pure, and safe.
In this test, tiny amounts of bacteria and fungi are purposely introduced into the formula (yes, really).
The goal? To confirm that Soke’s preservative system can stop them from growing.
This is crucial for hydrogel masks, which hold moisture — the perfect environment for microbes if they’re not controlled.
What this means for you:
Your mask stays safe from the day it’s made until the day you use it.
CA Proposition 65 Review
One of the world’s strictest ingredient safety standards.
Prop 65 screens for substances linked to cancer or reproductive harm. Many brands avoid this review because it’s so demanding. We chose to put Soke to the test — ensuring our formulas stay free of Prop 65-listed ingredients.
What this means for you:
A cleaner formula and full ingredient transparency.
Regulatory Review of Ingredients & Claims
Every word we say is backed by data.
Before a single product is released, regulatory experts analyze:
- the ingredient list
- the formula
- and the claims on the box
This is how we can confidently say “clinically proven” and “multi-peptide infused technology” — because the science supports it.
What this means for you:
Claims you can believe in, not marketing gloss.
Freeze–Thaw Stability Test
Making sure your mask survives winter shipping — and summer storage.
The hydrogel is repeatedly frozen, thawed, and tested again. The goal is to mimic the extremes a product may experience in transit or storage.
What this means for you:
The texture, firmness, and peptide potency remain consistent — even if the box sat in a freezing warehouse or a warm bathroom cabinet.
Elevated Temperature Stability
Simulated aging, in fast-forward.
The hydrogel is stored at high temperatures for extended periods. This accelerates aging and reveals how the formula will hold up months or years later.
What this means for you:
A mask that performs beautifully on day 365 — not just day one.
Heavy Metals Testing (ICP-MS)
Ultra-sensitive screening for trace contaminants.
Using Inductively Coupled Plasma Mass Spectrometry (a technique normally used in medical labs), the formula is scanned for lead, mercury, arsenic, and cadmium at parts-per-billion levels.
What this means for you:
A hydrogel that meets — and often exceeds — Health Canada and international purity standards.
Human Repeat Insult Patch Test (HRIPT)
50 humans. Multiple applications. Dermatological supervision.
This test evaluates whether a formula causes irritation or sensitization.
Across all participants, Soke’s hydrogel demonstrated excellent skin compatibility, with no significant irritation observed.
What this means for you:
A treatment that feels gentle on the skin, even for people who react easily.
(As always, individual sensitivities can still happen — but the data shows Soke is well-tolerated by most.)
What All of This Means for You — The Real-Life Benefits
All of this testing ensures that what you put on your skin is:
Consistently effective
You get the same texture, potency, and results every time.
Scientifically validated
Independent labs confirm safety and purity — not just Soke.
Transparent and trustworthy
Every claim is backed by measurable results.
This is what happens when a brand treats skincare like something that should be proven, not merely promised.
Soke’s Standard: Proven by Science, Designed for Skin
Every Soke Hydrogel Mask reflects a commitment to clinical-level testing, ingredient transparency, and visible, real-world results.
Your skin deserves more than the minimum — it deserves skincare that’s tested, trusted, and purposefully designed to perform.
