WHAT

De-Crease was tested by an independent clinical testing facility in the UK, under standardised conditions. Princeton Consumer Testing are industry leaders in cosmetic testing and clinical trials; their specialist staff having conducted global studies with numerous brands in the skincare space since their inception in the early 1990s.

WHO

This trial involved 30 healthy, female participants aged between 30-65 years. All with visible fine lines and crow’s feet around the eyes. Princeton Consumer Testing is responsible for selecting, briefing, and onboarding all willing participants. These women had no knowledge of the product being from Go-To (before, during, or after the trial). Nor did they have direct contact with our formulations team.

HOW

Participants were instructed to use De-Crease retinal eye serum as their daily eye product, applying the required amount under and around the eyes every night, for 12 whole weeks. They were instructed to maintain their current skincare routine throughout this period.

Similarly, participants were not allowed to introduce any new products into their routine throughout the trial period, so that all changes observed in the condition of their skin could be confidently attributed to the introduction of De-Crease.

The eye serum was tested with the same real world directions we would (and do!) provide our customers.

RESULTS

To measure an increase in skin smoothness (or decrease in roughness) (same same) Princeton Consumer Testing facility creates skin surface replicas of all participants, specific to the crow’s feet area. They then tested these replicas by shining angled light across the face mould and measuring its luminance. Variances in luminance are proportional to how rough the skin’s surface is or isn’t.

The results obtained were statistically significant. Princeton Consumer Testing recommended a pool of 30 participants given the design of the De-Crease study, and this being a number plausible of determining large scale trends.
