Reaction Triage
Why is my skin reacting?
Answer a few questions about what you're seeing and what you've been using. We'll cross-reference the active ingredients in your routine and rank the most likely causes — purging, irritation, allergy, fungal flare, true breakout, or something that needs a dermatologist's eyes.
1. What does the reaction look like?
Pick the closest match — it's fine if you're unsure.
2. Where is it showing up?
3. Any of these feelings? (pick all that apply)
4. How long has this been going on?
Answer all 4 questions to continue
5. Have you started anything new recently?
6. Which actives are in your current routine?
Tick any you're using right now. We use this to weight the likely cause — e.g. purging only happens with specific ingredients.
7. Are you in any of these situations? (optional)
