Dark circles: what it measures, what moves it
Dark circles is one of 17 biomarkers SKINLINK scores on every scan. Healthy range: 75+ bright. This is what drives it and how to move the needle.
Dark circles 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 dark circles: pigmentation (most common in Indian skin), vascular thinning, structural hollows. Most of these are addressable in 4–8 weeks of consistent routine.
What moves it: vitamin C eye, caffeine, SPF; structural needs filler. Track week-over-week — small consistent gains compound.
How SKINLINK measures it: under-eye luminance delta vs cheek baseline. Your score updates every scan and feeds your daily GlowScore.
FAQ

75+ bright. Below that, your routine needs adjustment; above, hold steady.
How long until dark circles 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.
