Cold and heat both have legitimate uses in a routine. They're not better or worse — they're different tools for different things. The common mistake is treating one as the universal default.

Editor's note
Temperature is among the least-discussed variables in skincare, and one of the few where the mechanism is actually well understood. Cold narrows blood vessels, temporarily reduces puffiness, and can extend the life of a barrier that's been slightly overworked. Heat and steam open the follicular opening, which helps cleansing but also sensitises.
Cold in skincare
Cold towel finish and cold water rinse
Cold causes vasoconstriction — blood vessels narrow, which temporarily reduces visible redness and puffiness. It doesn't close pores permanently, but it does settle inflammation. A cold towel finish after cleansing is a functional choice for reactive skin, not purely a wellness ritual.
Heat and steam in skincare
Steam and warm applications
Heat and steam cause vasodilation — vessels widen, blood flow increases, and follicular openings relax. This makes cleansing more effective but increases skin reactivity. Applying potent actives immediately after steam carries more risk than on calm, un-heated skin. No more than five minutes of steam, and never directly before retinol or acids.
