As estrogen shifts and then declines through perimenopause, tissues across the face change in ways that decades of peer-reviewed research have documented: in the skin, in the bone beneath it, in the hairline and brows, at the surface of the eye, and in the way the face flushes. MARKABLE reads a broad set of these facial signals from a single selfie, and follows them over time.
Patterns associated with the transition. A general wellness product, not a diagnostic test, and it does not measure hormones.
Read in isolation, none of the changes below is specific to the hormonal transition; each is also driven by age, sunlight and genetics. Read together, and followed month over month, they form a pattern a woman and her clinician can follow together.
Estrogen is a key regulator of collagen production and dermal thickness, acting through receptors on the skin's own fibroblasts.3 As estrogen falls, dermal collagen declines, on the order of one to two percent per year in the first years after menopause, and it tracks time since menopause more closely than chronological age.1,2 The skin's surface and texture change with it.
Estrogen is a primary regulator of bone remodeling, and the facial skeleton is no exception. In a study of facial-shape trajectories, women's faces diverged sharply around age fifty, and the change was better predicted by years since the last menstrual period than by chronological age.4 The bony frame of the face, including the orbit around the eye, remodels over this window,5 gradually changing contour and volume.
Hair growth responds to the hormonal environment, and shifts in the hormonal balance around menopause are associated with changes in hair density in some women. The frontal hairline and the eyebrows are a recognized site of this change, with recession of the frontal hairline and thinning of the brows seen more often after menopause.6
The surface of the eye is hormone-sensitive, and across the transition many women notice changes in the tear film that show up as dryness or irritation around the eyes.7 The periorbital region also shifts as the bone around the eye remodels, changing the geometry of the eye area over time.
Vasomotor episodes, the hot flashes of the transition, produce visible facial flushing. Research on hot flashes has documented a sharp rise in facial skin blood flow during a flush, through neurally mediated vasodilation.8 Visibly, this shows up as shifts in skin tone and redness.
Facial analysis is strong precisely because it does not stand alone. MARKABLE fuses it with four more systems the transition touches. Combining signals, rather than trusting any one, is the established way to see a physiological pattern more clearly than a single measure can.9

That result carries a wide confidence interval (95% CI 0.72 to 0.97) on a small sample, with only twelve women in the control group, so it needs larger validation. A paper is in preparation for peer review, and full validation detail is available on request. MARKABLE reads patterns associated with the hormonal transition. It does not measure hormones, diagnose, or replace clinical testing.
