During a Cryofacial treatment, a trained technician utilizes a handheld device that emits blasts of intensely cold air, usually around -200 degrees Fahrenheit, directly onto the skin of the face and neck. This rapid and extreme cold exposure induces vasoconstriction, causing the blood vessels to temporarily narrow. As a result, blood flow to the treated areas decreases temporarily.
The sudden cold triggers a response in the body known as vasoconstriction followed by vasodilation, where the blood vessels first constrict and then expand. This process promotes circulation, sending nutrient-rich blood to the skin's surface once the treatment ends.
Additionally, the low temperature stimulates collagen production, tightening the skin and potentially reducing the appearance of fine lines and wrinkles over repeated sessions.
