https://skinframe.app/articles/ A photo-first rosacea tracker built around current dermatology consensus. en-US Thu, 04 Jun 2026 16:00:12 GMT support@sailquery.com (Skinframe) https://skinframe.app/articles/16m-rosacea-tracking-category/ https://skinframe.app/articles/16m-rosacea-tracking-category/ Thu, 28 May 2026 18:29:45 GMT Roughly 16 million Americans have rosacea. The category for tools that help them track it is one of the largest underbuilt niches in consumer health software. The published critiques converge on a small set of structural failures: phenotype-incorrect onboarding, collapsed severity scoring, ignored ocular phenotype, no skin-tone-equity work, and photo pipelines that fail serial comparability. This is the category-level argument for why a new entrant is worth building. Category Analysis https://skinframe.app/articles/post-covid-rosacea-wave/ https://skinframe.app/articles/post-covid-rosacea-wave/ Thu, 28 May 2026 18:29:45 GMT The canonical NRS 2002 trigger list is a great patient-survey dataset and it is also missing the largest single new rosacea-trigger event of the last decade. A 34 percent post-COVID exacerbation rate in one retrospective study and a 28.8 percent post-infection rate in a 2025 cross-sectional study describe a trigger pattern the 2002 framing has no field for. Triggers https://skinframe.app/articles/every-derm-app-fails-clinical-photography/ https://skinframe.app/articles/every-derm-app-fails-clinical-photography/ Thu, 28 May 2026 18:29:44 GMT Auto white balance is explicitly discouraged in serial clinical photography. Flash creates specular hotspots that destroy erythema scoring. Standardized lighting, manual white-balance lock, fixed distance, dark blue background for skin of color: these are not opinions. They are the published protocol. Almost no consumer dermatology app implements any of them. The result is a photo set you cannot serially compare. Methodology https://skinframe.app/articles/demodex-the-rosacea-factor/ https://skinframe.app/articles/demodex-the-rosacea-factor/ Thu, 28 May 2026 18:29:44 GMT Rosacea patients have roughly 4 times the Demodex mite density of healthy controls. Topical ivermectin, which kills the mites, reduces rosacea lesions in randomized trials. The mites are there, the treatment that targets them works, and the causal story is still being worked out. We are going to explain what the literature actually says and what it doesn't, in plain language, without recommending you do anything beyond bring this up with your dermatologist. Treatments https://skinframe.app/articles/estrogen-protective-hypothesis/ https://skinframe.app/articles/estrogen-protective-hypothesis/ Thu, 28 May 2026 18:29:44 GMT Postmenopausal patients sometimes report their rosacea getting better, not worse, when the literature might predict the opposite. The Nurses' Health Study II analysis on exogenous hormones found that menopausal hormone therapy and oral contraceptives are dose-responsively associated with increased incident rosacea risk. Both findings line up with an estrogen-modulated mechanism dermatology has been quietly working out for years. Triggers https://skinframe.app/articles/red-wine-vs-white-wine/ https://skinframe.app/articles/red-wine-vs-white-wine/ Thu, 28 May 2026 18:29:43 GMT Two separate strands of rosacea-and-alcohol research disagree at first glance, then reconcile in a way that matters at a wedding dinner. The NRS 2010 acute-flushing survey put red wine far ahead of white as a trigger. The Li 2017 NHS cohort found white wine and liquor associated with incident rosacea risk and red wine, not statistically associated. The disagreement is real, and the two findings are about different things. Triggers https://skinframe.app/articles/its-the-temperature-not-the-caffeine/ https://skinframe.app/articles/its-the-temperature-not-the-caffeine/ Thu, 28 May 2026 18:29:43 GMT Most rosacea patients learn from forum lore that they have to give up coffee. The published evidence is the opposite. A case-control study found that 60°C water and 60°C coffee produced equivalent flushing, and both at 22°C did not. A 82,737-woman cohort showed caffeine intake is inversely associated with incident rosacea risk. The trigger is the heat, not the chemistry. Triggers https://skinframe.app/articles/what-dermatologists-actually-want/ https://skinframe.app/articles/what-dermatologists-actually-want/ Thu, 28 May 2026 18:29:43 GMT The published preferences are clear and the consumer-app category has mostly ignored them. Dermatologists want a single-page summary with the flare count, the top trigger co-occurrences, two photos, and the quality-of-life trend. They explicitly do not want 90 daily photos, a dashboard URL, or a pseudo-diagnostic score the patient pulled off an app. The 12-minute visit makes this concrete.

The 2017 phenotype framework lists ocular manifestations as a major phenotype, on its own line, with diagnostic weight. Most rosacea trackers don't have a field for it. Methodology https://skinframe.app/articles/every-rosacea-severity-score-feels-broken/ https://skinframe.app/articles/every-rosacea-severity-score-feels-broken/ Thu, 28 May 2026 18:29:42 GMT Patients complain that their tracker's single severity number doesn't reflect what their face is actually doing. It turns out that complaint matches a published critique of the Investigator Global Assessment scale that dermatology has been working with for years. The collapse-into-one-number problem is structural, not a UX bug. Methodology https://skinframe.app/articles/rosacea-on-every-skin-tone/ https://skinframe.app/articles/rosacea-on-every-skin-tone/ Thu, 28 May 2026 18:29:42 GMT Reported rosacea prevalence in Fitzpatrick IV-V skin sits at roughly 6 to 8 percent of the rosacea-diagnosed population. The literature is explicit that a meaningful share of that gap is diagnostic masking, not biology. Telangiectasia is harder to see against pigmented skin, and the dermatology image-classification models trained to spot it perform 3 times worse on darker skin than on lighter. We built Skinframe to not make that mistake worse. Methodology https://skinframe.app/articles/rosacea-apps-2017-update/ https://skinframe.app/articles/rosacea-apps-2017-update/ Thu, 28 May 2026 18:29:05 GMT In 2017, the dermatology field formally retired the four-subtype rosacea model and replaced it with a phenotype framework. Nine years later, every rosacea-named tracker on the App Store still opens with "which type of rosacea do you have?" That question has a name in the literature, and the literature has moved on.
