What are the essential precautions to follow after cheek filler injections?

I decided to get filler treatment because I was stressed that the sunken sides of my cheeks made my impression look a bit sharp. I am looking forward to naturally adding volume to make my look much softer, but since this is my first time getting fillers, there are many things I am cautious about. In particular, I heard that the most important thing is to follow the precautions to prevent the shape from changing immediately after the procedure.

Aside from avoiding touching or applying pressure to the treated area, what other precautions regarding fillers are easy to overlook in daily life? For example, I am curious if wearing glasses or sleeping posture affect the filler's longevity or shape. I am sure the director at Maypure will explain this in detail, but I think I would feel more at ease knowing this information in advance.

Is there anyone who would like to share their experiences regarding methods that helped reduce swelling or bruising quickly after the procedure, or any essential precautions regarding fillers to avoid? Since this is a significant decision I’ve made, I simply want to maintain a beautiful shape for a long time without any side effects. I look forward to hearing your valuable tips!
