The science
Peritale reflects general wellness signals, facial patterns, attention and memory, hearing, vision and how you feel, and shows how they line up over time. It is built on a proprietary research dataset, patent pending. Here is what we look at, what it may mean, and what we never claim.
A general wellness check-in for self-awareness, not a medical test or a diagnosis. Peritale reflects general patterns that may be associated with the hormonal transition of midlife. It does not measure hormones and does not detect, diagnose, screen for, treat, prevent or manage any condition.
What Peritale reads
No single signal tells the whole story. Peritale brings together four independent channels, each reflecting a different part of how this stage of life shows up in your body, mind and senses, for personal awareness only.
From a standard smartphone selfie, Peritale reflects general facial patterns, things like skin texture, tone and facial proportions, that may shift through this stage of life. This is a general wellness signal, not a skin diagnosis.
A short, game-like check of attention, word-finding, recall and processing speed. Changes in focus and memory are among the experiences women report most often in this stage.
Quick checks of two senses that can quietly shift during midlife. They add a functional layer to your picture that a questionnaire alone would miss.
You tell us what you are feeling across sleep, mood, energy, focus and body. Peritale maps which symptoms cluster together, so your experience is part of the picture, not an afterthought.
Why a selfie can say something
Hormones such as estrogen and progesterone play a role in skin health, influencing collagen, hydration, blood flow and cellular turnover. As hormone levels fluctuate through the hormonal transition of midlife, some of these effects may become visible in subtle ways.
Published research has described how estrogen decline is associated with changes in skin elasticity, thickness and microcirculation. Day to day these changes are easy to miss, but they can accumulate over weeks and months, in patterns that software may read from a standard photo.
A selfie cannot replace a blood test. It can offer a general wellness signal that, alongside the other channels, helps complete your picture. It does not diagnose any condition.
Stronger together
Each channel captures something the others cannot. Facial patterns reflect cumulative changes that build up over weeks. The focus and memory check captures real-time processing in the moment. Hearing and vision add a functional layer. Your symptoms carry your lived experience, which no measurement can replace.
In Peritale's early validation data, bringing the channels together was more informative than any single channel on its own. That is the whole idea behind a multi-signal read: a fuller, more honest picture than one number ever could give.
What this is, in plain terms. Each signal gets its own score and a simple status. Together they each become a clear score you watch over time. Together they give you one personal picture, your own baseline and trend, not a grade and not a diagnosis. A score moving up or down is a prompt to pay attention and to talk with your provider, never a verdict about your health.
About the research
Peritale's approach is built on a proprietary research dataset of more than two hundred and fifty women in midlife, analysed using a published midlife hormonal-transition reference standard. Participants completed smartphone selfie analysis, short thinking and senses checks, and a symptom questionnaire covering more than seventy areas.
The dataset includes facial parameters read by software, focus and processing-speed measures, and self-reported symptom clusters across sleep, mood, cognitive and physical domains. The analysis used leave-one-out cross-validation, a standard method to guard against over-fitting on a dataset this size.
Our early research dataset was self-referred and we did not track participant demographics, so we are careful not to overstate performance across every skin tone or population. Validating fair performance across diverse skin tones and settings is a priority as we expand. Wider, multi-centre work is part of the roadmap.
This is early validation data, not a clinical trial. The strongest combined results came from a smaller group of women who completed every module, a promising signal that needs confirmation in larger, multi-site studies. Peritale is a wellness awareness tool, not a clinical or diagnostic instrument.
Our position. Peritale is a general wellness product for personal self-awareness and self-tracking. It does not detect, diagnose, treat, cure, prevent or manage any disease or condition, and it does not measure your hormones. We encourage everyone to share their picture with a qualified healthcare professional.
Why trends, not snapshots
Traditional hormone testing relies on a blood draw, which captures one moment in time. Through this stage of life, hormone levels can swing considerably even within a single day, which is part of why a single draw can be hard to read on its own.
Peritale takes a different angle. Rather than measuring hormones, it reflects general patterns that may be associated with hormonal change, and lets you follow your own picture from one monthly check-in to the next. This is not a replacement for blood testing. It is a complementary wellness companion that shows trends rather than single snapshots.
Peritale does not diagnose or evaluate any treatment. What you see move over time is your own picture, your score and your signals, never a verdict on whether a specific medication or routine is working.
Built on real measurement, not vibes
