The whole list, first

Postpone saunas, jjimjilbang, hot baths and vigorous exercise for a few days. That is the list.

If you were expecting more, that reaction is worth sitting with, because it is the reason this page exists. A great many English pages about Thermage aftercare carry fifteen or twenty rules, and most of them are not traceable to anything. They are there because a long list looks thorough.

A treatment that is classed as having minimal downtime, and that is not intended to leave open wounds or scabbing, does not generate fifteen rules. It generates a few, and they all point at the same thing.

• Postpone saunas and jjimjilbang for a few days
• Postpone hot baths for a few days
• Postpone vigorous exercise for a few days

Why every item is heat

Thermage works by delivering radiofrequency energy into the dermis, which is a controlled way of heating tissue. In the days that follow, the sensible thing is not to add uncontrolled heat on top of it while the skin is settling.

Once you see the principle, you do not need to memorize the list. Anything that raises your skin temperature substantially belongs in the same category, whether or not it appears on a page. That is a more useful thing to carry around than a list of nouns.

It also explains the shape of the timeline. Redness and warmth usually settle within one to two days, and the postponement is measured in a few days rather than weeks. This is a short adjustment, not a new routine.

The part that matters if you are in Seoul

Jjimjilbang is on almost every Seoul itinerary, often on the same day as a treatment because both are things you do indoors. It is the single easiest thing to walk into without thinking about it, which is why it is worth naming rather than leaving under a general heading.

Hotel spas, saunas at the gym and long hot showers sit in the same category. None of them is a crisis and none of them needs planning around beyond moving it a few days later in the trip.

The scheduling version of this is simple: book the bathhouse for the end of your trip rather than the middle, and the question resolves itself.

What we are deliberately not telling you

We are not publishing a general list of products to stop using, days to stay out of the sun, or foods to avoid. Not because those questions are unreasonable, but because the answers depend on your skin, your plan and anything else being treated in the same visit — and a page cannot know those.

At the clinic, post-treatment precautions and predictable side effects are explained in detail before you leave. That conversation is specific to you in a way this page cannot be, and it is the version worth following.

If something appears afterwards that does not match what you were told, the right move is to contact the clinic rather than to search for it. English questions are answered over WhatsApp, including after you have flown home.

• Ask for your own precautions in writing before you leave the clinic
• Contact the clinic rather than searching if something looks different from what you were told
• WhatsApp questions are answered after you are home as well
