The consensus across specialist skincare communities we read is that the effects are real but temporary. Reddit threads in r/SkincareAddiction, r/beauty and r/IndianSkincareAddicts repeatedly explain that cold tools cause vasoconstriction and lymphatic-style massage that briefly reduce puffiness and redness, with results fading within hours. They are best understood as a soothing, depuffing ritual rather than an anti-aging treatment.
