Twenty evidence-based questions about your skin, your habits, and your routine. Under two minutes, a scored report with exactly what to fix — and what's already working.
Your skin barrier isn't just one thing — it's a system. This assessment scores four interconnected factors that research links to barrier integrity, then combines them into a single score out of 100.
Current signs of barrier compromise: tightness, stinging, flaking, redness, reactivity, texture changes, and unexplained breakouts.
Whether your current products support or stress the barrier: cleansing approach, actives load, moisturiser type, and SPF usage.
Daily behaviours that impact barrier function: water temperature, exfoliation frequency, product introduction pace, and sleep patterns.
External stressors that weaken the barrier: climate, indoor heating/AC, pollution exposure, and seasonal transitions.
Select the answer that best describes your current skin. There are no trick questions — honest answers give the most useful results.
20 questions across four categories: symptoms, routine, habits, and environment. Each maps to a researched barrier-health factor. Takes under 2 minutes.
Answers are weighted and combined into a single 0–100 barrier health score, broken down by dimension so you can see exactly where the weak points are.

The skin barrier — technically the stratum corneum — is the outermost layer of your skin. It's made of flattened dead skin cells (corneocytes) held together by a lipid matrix of ceramides, cholesterol, and fatty acids, often described as a "bricks and mortar" structure. A healthy barrier keeps moisture in and irritants, allergens, and pathogens out.
Common signs include persistent tightness or dryness, stinging when applying products that didn't sting before, redness or flushing, flaking or rough texture, increased sensitivity or reactivity, and breakouts in areas where you don't normally break out. This assessment checks for all of these signs and scores their severity.
Research suggests mild barrier disruption can recover in 2–4 weeks with proper care. More significant damage — from chronic over-exfoliation, retinoid overuse, or prolonged environmental exposure — may take 6–12 weeks. The key is stripping your routine back to barrier-supportive basics: gentle cleanser, ceramide-rich moisturiser, and SPF.
No. This is an educational self-assessment based on published dermatological research. It can help you understand your barrier status and make smarter product choices, but it cannot diagnose skin conditions. If you have persistent or worsening symptoms, please see a qualified dermatologist.
Yes. It's designed to be retaken — after making changes to your routine, reassess in 3–4 weeks to track your barrier recovery over time.
