Enhance your TheraFace PRO routine with these Hot/Cold Rings Attachments in White. Designed to work with the Theraface Pro Face Massager (sold separately), these rings utilize Cryothermal Technology for rapid cooling and heating, offering 3 temperature options for each ring. The hot ring can help increase blood flow, reduce tension, and alleviate pain. The cold ring is effective for reducing under-eye puffiness, pain, inflammation, and muscle spasms. Both rings contribute to better absorption of creams and improved skin radiance. You can also combine the cold ring with the TheraFace Massager's percussive attachment (sold separately) for a customized regimen. Please note: Avoid using the Hot Ring if you have melasma or hyperpigmentation, especially if it is exacerbated by mild warmth. This package includes 2 units and a convenient case.
