Hydration: what it measures, what moves it
Hydration is one of 17 biomarkers SKINLINK scores on every scan. Healthy range: 60–80% optimal. This is what drives it and how to move the needle.
Hydration 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 hydration: low humidity, over-cleansing, dehydration, AC exposure. Most of these are addressable in 4–8 weeks of consistent routine.
What moves it: humectants (HA, glycerin) on damp skin, sealed with an occlusive; 2L water/day. Track week-over-week — small consistent gains compound.
How SKINLINK measures it: stratum corneum reflectance and translucency mapping. Your score updates every scan and feeds your daily GlowScore.
FAQ
What's a good hydration score?
60–80% optimal. Below that, your routine needs adjustment; above, hold steady.
How long until hydration 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.
