WHAT
Clarifying Face Hero was tested by an independent clinical testing facility in Sydney, under standardised conditions. Ozderm are industry leaders in cosmetic testing and clinical trials.
WHO
This involved 28 healthy female participants aged between 18-43 years, with skin prone to breakouts and pimples. Ozderm is responsible for selecting, briefing, and onboarding all willing participants. They had no knowledge of it being a Go-To product (before, during, or after the trial) nor were they in contact with our Formulations team.
HOW
Participants were instructed to apply three drops of Clarifying Face Hero to their whole face after cleansing and before moisturising, for the full 8 weeks.They were instructed to maintain their current skincare routine too. (For any Nosy Nellie’s we are not privy to what other products and brands our participants use.)
Similarly, participants were not allowed to introduce any new products into their routine throughout the trial period, so that any changes observed in the condition of their skin could be confidently attributed to the introduction of Clarifying Face Hero.
Because the participants added Clarifying Face Hero to their routine, they tested this product with the same real world directions for use that we would (and do!) provide our customers.
RESULTS
When we mention claims about the skin barrier strength, this is aligned with transepidermal water loss (TEWL), which describes how much water evaporates from the skin. Using a Tewameter®, with sensors that measure moisture levels in the skin based on both temperature and humidity, this evaporation or loss of water is considered to be proportionate to how intact or strong the skin barrier is. Skin that is deficient of certain properties or otherwise impaired will have a greater rate of evaporation than one that is considered to have good barrier function.
We can say Clarifying Face Hero balances oily skin because sebum production was measured throughout the trial using a Sebumeter®. (We swear we aren’t making these up.) This instrument measures the amount of sebum on the skin using a special tape which turns transparent when it comes into contact with oils. The more sebum there is present, the more transparent the tape becomes, and this allows for a quantitative measurement of skin oiliness based on grease-spot photometry.
So, skin lesions. Your breakouts and blemishes. To determine this decline our clinicians simply took digital photographs of every face, regularly throughout the trial, to count visible pimples on the face.
The results obtained were statistically significant. Ozderm recommended a pool of 28 participants given the design of the Clarifying Face Hero study, and this being a number plausible of determining large scale trends.
