Barrier: what it measures, what moves it
Barrier is one of 17 biomarkers SKINLINK scores on every scan. Healthy range: 70+ healthy. This is what drives it and how to move the needle.
Barrier on Indian skin behaves differently from the Western dermatology playbook. Our model is calibrated for Fitzpatrick III–VI tones, Indian climate (humidity, UV, AQI), and the cultural realities of Indian routines.
What drives barrier: harsh actives, hot water, fragrance, over-exfoliation. Most of these are addressable in 4–8 weeks of consistent routine.
What moves it: ceramides, cholesterol, fatty acids in a 3:1:1 ratio; pause actives for 14 days. Track week-over-week — small consistent gains compound.
How SKINLINK measures it: redness vector + micro-texture irregularity. Your score updates every scan and feeds your daily GlowScore.
FAQ
What's a good barrier score?
70+ healthy. Below that, your routine needs adjustment; above, hold steady.
How long until barrier improves?
Most users see measurable gains in 4–8 weeks with consistent routine. Pigmentation and elasticity take longer (8–16 weeks).
Is the biomarker score clinically validated?
Our model is benchmarked against dermatologist visual scoring and Visia-class imaging. It's directional, not diagnostic — see a derm for clinical concerns.
