Redness: what it measures, what moves it
Redness is one of 17 biomarkers SKINLINK scores on every scan. Healthy range: <30 calm. This is what drives it and how to move the needle.
Redness 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 redness: barrier damage, rosacea-tone, alcohol, hot water, fragrance. Most of these are addressable in 4–8 weeks of consistent routine.
What moves it: centella, azelaic acid, mineral SPF, cool water cleansing. Track week-over-week — small consistent gains compound.
How SKINLINK measures it: a* axis vector intensity in CIELAB space. Your score updates every scan and feeds your daily GlowScore.
FAQ
What's a good redness score?
<30 calm. Below that, your routine needs adjustment; above, hold steady.
How long until redness 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.
