P&K Skin Clinical Research Centre. Primary Skin Irritation Test. Seoul, Korea. 2023.
Independent open-label, single-arm 24-hour patch test on Vitamin C filter material. n=30 (28F/2M, mean age 47.2 years). Skin Irritation Index 0.03 (range 0.00-0.25 = non-irritant). Zero adverse events. Frosch and Kligman + CTFA + Draize protocols, COLIPA Walker 1996 guideline. Sample size and design are appropriate for a tolerability/irritation screen, not a clinical efficacy trial.

Korea Environment and Water Works Institute (KEWI). Residual Chlorine Removal Test. Seoul, Korea. 2020.100... lab test
Korea Environment and Water Works Institute (KEWI). Residual Chlorine Removal Test. Seoul, Korea. 2020.
100 L synthetic water at 0.19 mg/L free residual chlorine, passed through Vitamin Filter. Outlet: not detected. Flow 2.52 L/min. T = 21-23 degrees C.
Note: real shower conditions are typically higher pressure and warmer than this laboratory test. The Vitamin C gel cartridge is engineered as a self-regulating system: higher pressure releases more Vitamin C from the gel matrix, and higher temperature accelerates the chlorine-neutralisation reaction. Under typical shower conditions these dynamics are expected to keep real-use performance broadly comparable to the laboratory result.
