We Sent Our Eye Cream to an Independent Lab. Here Are the Results.
We already believed this product worked.
We had used it ourselves. We had collected feedback from testers. The results were consistent. But personal experience and brand testing are not the same as independent science.
So we sent the Re/Boost Collagen Smooth & Bright Eye Cream to a certified dermatological laboratory in Poland — with no involvement in the outcome. We gave them a clear brief: test whether this cream actually reduces wrinkles, brightens dark circles, and improves skin elasticity. Prove it or don't.
Here is what they found.
The Study Setup
Twenty volunteers used the eye cream daily for four weeks, following a standardized protocol. During the study, they used no other eye area products.
After four weeks, a dermatologist evaluated ten volunteers in detail. Three things were measured using clinical instruments: skin brightness around the eyes, wrinkle depth and length, and skin elasticity. Before and after photographs documented visible changes in dark circles.
Result 1: Brighter, More Even Skin Under the Eyes
16 of the 20 participants began the study with noticeable dark circles.
Skin brightness was measured using a Konica Minolta 600D spectrophotometer — a clinical device that reads the exact color and tone of skin. After four weeks of daily use, 7 out of 10 measured volunteers showed a measurable increase in brightness under the eyes. The skin tone in that area became more even.
The instrument readings were confirmed by the before and after photographs.
Result 2: Visibly Fewer and Shallower Wrinkles
Wrinkle length and depth were measured using the Courage + Khazaka Visioline VL 650 system. The lab created silicone replicas of each volunteer's skin surface and analyzed them using specialized imaging software. This method captures details the eye cannot see.
Wrinkle length decreased in 8 out of 10 volunteers. The reduction ranged from 6% to 19%. The average across the group was an 11% decrease.
Wrinkle depth decreased in 8 out of 10 volunteers. The reduction ranged from 5% to 14%. The average across the group was an 8% decrease.
Result 3: More Elastic, Firmer Skin
Skin elasticity was measured using the Courage + Khazaka Cutometer MPA 580 — a device that applies controlled suction to the skin and measures how quickly and fully it returns to its original state. This is one of the most precise ways to assess skin firmness.
9 out of 10 volunteers showed improved elasticity after four weeks. Individual improvements ranged from 6% to 23%. The average improvement across the group was 16%.
What the Independent Lab Confirmed
Based on the full study results, the laboratory confirmed that Re/Boost Collagen Smooth & Bright Eye Cream delivers the following:
- Reduces the length and depth of wrinkles around the eyes
- Improves skin elasticity and firmness
- Helps reduce the appearance of dark circles and puffiness
- Hydrates the skin and improves moisture retention
- Smooths skin texture
- Brightens and evens out skin tone under the eyes
- Supports skin renewal
These are not brand claims. They are independently verified outcomes.
The Ingredients Behind the Results
The formula combines senolytic active ingredients, bio-retinol from Bidens Pilosa, caffeine, and botanical extracts including alpine willowherb, horse chestnut, horsetail, avocado, and red algae harvested from the Estonian coast.
The star ingredient is bio-retinol derived from Bidens Pilosa — a plant that activates the same collagen and elastin-producing receptors in the skin as synthetic retinol, without any of the irritation, peeling, or sun sensitivity that retinol users know well. No break-in period. No synthetic derivatives.
Every ingredient is of natural origin. The full Re/Boost Collagen range is certified by ECOCERT under the COSMOS Standard.
Why Independent Testing Matters
The clean beauty market is full of claims. "Clinically tested." "Dermatologist approved." These phrases often mean very little without transparency about how the testing was done, who did it, and what the actual numbers were.
We chose to work with an independent laboratory and share the full methodology and results — not a simplified summary, not a marketing stat pulled out of context.
If you want to know more about how we formulate, what ECOCERT certification actually requires, or how bio-retinol works at the skin level, those answers are on our site.
