It is generally recommended to avoid saunas and steam rooms for at least 2–3 days after a procedure, or around 1 week for heat-based treatments. This is because the high temperature of a sauna can dilate blood vessels in the treated area, worsening swelling and redness, and can add extra irritation to the recovering skin barrier.
In particular, if the procedure leaves micro-wounds on the skin, such as with laser or injection treatments, a hot, humid environment can also increase the risk of bacterial infection. Even after treatments that deliver heat to the dermis or fascial (SMAS) layer, such as Thermage® FLX or Ultherapy PRIME®, applying strong heat from the outside again can cause swelling to persist longer.
For the same reason, it is advisable to avoid bathing, hot springs, and steam towels in the early period. Most patients can wash their face and shower with lukewarm water on the day of or the day after the procedure, so please follow the specific timing guidance provided for your treatment type.
