Start with the question
We begin with a concrete reader problem rather than a keyword list. A useful page should answer a real question, explain uncertainty, and tell the reader when general information is not enough.
Trust & research
Evidence, sources & limits
CareLens is an educational product, not a medical authority. This page explains where our health information comes from, how we decide what belongs in a guide, and what a photo-based AI system cannot establish.
Prefer primary and public sources
We prioritize professional medical organizations, government health agencies, systematic reviews, and primary research where appropriate. We use consumer sources as context, not as proof.
Separate evidence from advice
A plausible routine idea is not the same as a clinical recommendation. Our articles aim to distinguish established information, reasonable practical suggestions, and areas where evidence remains limited.
What a CareLens photo can—and cannot—tell you
A photograph contains visual information, not a complete health record. Lighting, camera quality, makeup, skin tone, angle, expression, hair styling and image compression can all change what is visible. A photo cannot reliably establish laboratory values, hormone levels, vitamin or mineral status, sleep quality, stress, diet, hydration status, medication effects, or the cause of a symptom.
CareLens therefore uses photo analysis to organize visible observations and educational options. It should not be used to confirm or rule out a disease, decide whether a prescription medicine is appropriate, or replace an examination by a qualified healthcare professional.
Our public source library
These links are starting points for readers who want to verify or explore the topics covered across the CareLens Journal. Individual articles may also include topic-specific sources. External organizations control their own pages and recommendations.
Dermatology & skin
For skin-care education we prioritize dermatology organizations and patient-facing clinical guidance. These sources help us distinguish routine cosmetic care from symptoms that need professional assessment.
Hair & scalp
Hair shedding and hair loss have many possible causes. We use dermatology guidance as a starting point and avoid treating a photograph as a way to determine the underlying cause.
Nutrition & everyday health
For nutrition we prefer public-health guidance over restrictive wellness trends. General dietary information is not a substitute for individualized nutrition care, especially for pregnancy, eating disorders, chronic disease, allergies, or medication interactions.
Sleep, activity & wellbeing
Lifestyle guidance is framed as general education. CareLens does not infer sleep quality, stress, mood, exercise, diet, hydration status, or nutrient deficiency from a face photograph.
How we handle uncertainty
Established
When multiple authoritative sources consistently support a basic point, we describe it directly and link readers to the relevant source category.
Limited
When evidence is mixed, indirect, observational, early-stage, or highly dependent on the individual, the wording should reflect that uncertainty.
Unknown
When a photograph or the available information cannot answer a question, CareLens should say so rather than filling the gap with a confident-sounding explanation.
Updates and corrections
Health guidance changes. When we identify a material factual error, unsafe wording, broken source, or outdated recommendation, we aim to correct it rather than preserve it for search traffic. Readers can report an issue through the Contact page.

Use the information as a starting point
CareLens is most useful when it helps you understand a topic well enough to ask better questions. If a symptom is severe, persistent, rapidly changing, painful, associated with significant illness, or otherwise concerning, seek appropriate professional care.
