The Physiology of Cold Therapy
Cold therapy, or cryotherapy, has long been used in sports medicine to manage swelling and inflammation. In skincare, applying cold temperatures to the face—using ice rollers or ice globes—works by triggering vasoconstriction, the temporary narrowing of blood vessels.
Reducing Inflammation and Redness
By narrowing the blood vessels, cold therapy helps reduce blood flow to the surface of the skin, which can help calm redness and soothe irritation. When the skin warms back up, blood vessels dilate, bringing fresh, oxygenated blood to the area.
"Ice rolling is a simple way to help calm redness, ease morning puffiness, and soothe tired skin."
How to Use an Ice Roller
For best results, store your roller in the freezer. Cleanse your face, apply a hydrating serum, and roll gently in upward and outward motions. Focus on the under-eye area and jawline to help ease tension and reduce puffiness. Keep the roller moving to avoid excessive cold exposure on one spot.
