Do you know the differences between a copper-made gua sha and a stainless steel - made one?

• Stainless steel gua sha: They are made of alloy steel, with a hard texture, being wear-resistant and not easily damaged. Their surfaces are smooth, easy to clean, and not prone to bacteria growth, ensuring hygienic use.
• Copper gua sha: Copper is a good material for heat and electricity conduction. It has a relatively soft texture and good plasticity, and can be easily processed into various shapes.

Scraping Effects

• Stainless steel gua sha: Since they are relatively hard, it's easy to control the strength when scraping, and they can accurately stimulate acupoints and meridians. They are suitable for people who need stronger strength to dredge meridians.
• Copper gua sha: Due to their good thermal conductivity, they can be used for hot scraping after being heated (such as soaking in warm water), which can better promote blood circulation. Meanwhile, with a softer texture, they slide gently on the skin and are suitable for people with sensitive skin.

• Stainless steel gua sha: They hardly require special maintenance and are not afraid of rusting. Just rinse them with clean water and wipe them dry after use.
• Copper gua sha: Attention should be paid to preventing oxidation and discoloration. They need to be wiped dry in time after use. If oxidized, a special copper maintenance agent can be used to wipe them to restore their luster.
