Tool use should be avoided on areas experiencing active acne, rosacea flares, broken skin, or significant inflammation, as pressure and shear can increase superficial redness in sensitized tissue. Temporary erythema may occur when tools are used over inflamed areas, and use should be avoided when the skin barrier is compromised. If you have underlying medical conditions, active skin inflammation, circulatory concerns, or uncertainty about safe use of any tool, consult your physician or dermatologist before beginning a routine. 

All tool materials are interpreted consistently across cultural and Western systems. Cultural frameworks describe cooling or warming, stabilizing qi, balancing yang, reducing pitta, and supporting surface harmony. Western physiology describes cooling or warming, transient vasoconstriction, gentle activation, superficial shear, and light lymphatic movement. These interpretations refer to surface‑level effects only.

All tool materials act at the surface level and do not influence deeper structures. Mechanical forces such as cooling, warming, superficial shear, and light lymphatic movement operate only within the skin and do not extend into deeper fascia or bone. No material has been associated with deeper tissue manipulation, structural change, organ detoxification, trauma release, permanent lifting, or alteration of bone or fascia architecture.
