Frequently Asked Questions
How do I know if my skin symptom is serious?
Warning signs include: rapid spreading, fever, difficulty breathing, blistering across large areas, signs of infection (pus, red streaks, warmth), or symptoms that don't improve with basic care. Each symptom guide above lists specific red flags to watch for.
Can I use the AI scanner for any skin symptom?
Our AI scanners work best with clear photos of visible skin changes. They can help identify patterns and suggest possible causes, but are not a replacement for professional diagnosis. Always consult a healthcare provider for concerning symptoms.
When should I see a doctor for a skin problem?
See a doctor if: the problem is getting worse, home treatments aren't helping after 1-2 weeks, you're unsure what it is, it's affecting your quality of life, or you have any of the warning signs listed in our symptom guides.
