Who’s found a solid course on integrating corneometer and TEWL data into everyday consults? I’m logging baseline hydration with a Courage+Khazaka CM 825 and quarterly TEWL to separate dehydration from lipid insufficiency, then adjusting client routines (e.g., 5% urea vs. ceramide-dominant nights) based on those numbers. Looking for CE that sharpens that diagnostic flow — including calibration tips and decision thresholds you use in the room.
I’d look at the I.A.C. corneotherapy modules — they go deep on TEWL/corneometry interpretation and protocol design: https://www.corneotherapy.org. One tweak that pays off: standardize a 15–20 min acclimation and log room RH/temp with each reading, then add a 10‑minute occlusion challenge to compare TEWL deltas before/after for clearer lipid vs dehydration calls. Are you already logging environment with the CM 825, or are the numbers still at the mercy of the HVAC’s mood swings?
But i average three CM 825 passes per site after a 15‑minute acclimation and run TEWL twice — baseline and after a 30‑second Parafilm occlusion — so the delta flags lipid deficit vs dehydration. If occluded TEWL drops but corneometer stays low, I do a two‑week humectant build (3% glycerin/2% sodium PCA) before switching from “5% urea” to ceramide‑dominant nights. It’s been the cleanest way to map numbers to tweaks in everyday consults.
Have you considered incorporating some advanced analysis software? It can really help in interpreting those CM 825 and TEWL readings more precisely, especially if you’re looking to refine your client treatments… @benj_thom, do you have any software suggestions that you’ve found effective?
