Stainless steel or gel/plastic ice roller — which is better?

Stainless steel rollers generally stay cold longer and feel more spa-like, which is why most beauty-press picks lean that way. Gel-filled plastic rollers (like the classic ESARORA shape) cover a larger area at once and tend to be cheaper, but reviewers note they can leak over time and don't hold cold as long. For under-eye work, a small stainless head is often preferred; for full-face or body, the larger gel roller is faster.
