Are there many precautions to follow for InMode?

Lately, every time I look in the mirror, I'm stressed because the sagging skin under my chin makes me look so dull, so I've finally booked an appointment at a dermatologist for tomorrow. I'm planning to go for the FX mode, which burns away fat cells completely, but unfortunately, I have a prior commitment to go camping deep in the mountains with friends this Saturday.

I want to go light a bonfire, stare at the fire, and feel the cold mountain breeze. Are there any specific precautions I should take regarding InMode when engaging in outdoor activities immediately after the procedure? I’ve heard that the effect is better if the warmth is maintained on the face after the treatment, so I am extremely worried that exposure to very cold wind might hinder the fat from melting.

I spent a fortune getting an intense InMode treatment to get a V-line, but drinking alcohol or washing my face with cold water at the campsite won't do me any harm, right? Even if I cover the bruises with a mask, I'm scared the effects might wear off if I don't take proper care of it. To those of you who have experience with InMode and are often outdoors, please share lots of tips! ㅠㅠ
