When can I wash my face or apply makeup after getting fillers? I'm curious about the reviews.

Lately, whenever I look in the mirror, the sunken areas stand out particularly, so I'm considering getting fillers this week. I've heard that the lines become noticeably more defined after getting fillers, so I'm looking forward to it, but I'm a bit worried about daily care afterward.

I am wondering if I can wash my face or apply makeup immediately on the day of the procedure, and if I need to wear a mask for a few days due to injection marks or bruising. Also, is it possible for the shape to change if I accidentally touch or press the site after the injection? ㅠㅠ That is my biggest concern. And what was the starting dosage?
I would appreciate realistic advice on how long the natural results actually last after the procedure.
