What the guides cover
The guides are practical. They explain what tools are made of and how the materials differ, which edge fits which area, how to prepare and follow a gentle routine, and how to clean and store tools so they last. The sensitive skin and patch testing pages cover the precautions worth taking before you start.
No health or skin claims
Facial tools are often sold with promises about what they do for skin and faces. We don't repeat those claims or make our own. We describe how to use a tool gently and safely and leave it there. For any skin concern, or any question about whether a routine suits your skin, the right person to ask is a board-certified dermatologist.
No brands, no sales
We don't sell tools, oils or anything else. There are no partner links, sponsored posts or advertising, and no maker pays for mentions. We don't name or rate brands. The drawings on this site show general shapes, not any particular product.
How facts are handled
Material facts, such as hardness on the Mohs scale, are rounded and given as approximate, because figures vary between sources and samples. Care advice is deliberately cautious. Makers' instructions differ, so where your tool came with a care note, follow it. Guidance on patch testing and skin reactions is general. A dermatologist can give advice for your own skin.
Who it is for
The guides are written for adults who own a gua sha tool or roller, or are thinking about getting one, and want to use it carefully. If you are new to it, start with the tool shapes and the preparation page. If your skin reacts easily, read the sensitive skin page before anything else.
About the name
Gua Sha Stone is simply the name of this guide, chosen because the stone tool is what most readers start with. It isn't a shop, spa, clinic or maker, and it isn't connected to any business with a similar name.
