Is it okay for people who bruise easily after fillers?

I want to get fillers, but I'm worried because I bruise easily, so I'm asking for your advice.

Even a slight bump tends to leave lasting bruises, and perhaps because my skin is thin, the blood vessels under my eyes and around my mouth are slightly visible. I am looking into getting fillers for my nasolabial folds and cheeks, but I am worried that if I bruise severely, it will be too noticeable when I go to work.

I am wondering if people who bruise easily can get filler treatments, or if it is better to schedule with plenty of buffer time.

How long should I expect the bruising or swelling to last? Also, I heard that I should avoid alcohol or certain medications before the procedure; I would like to know if I can receive guidance on this during the consultation.

I want to naturally fill in just the sunken areas rather than making a big change, but I haven't been able to make an appointment yet because I'm worried about bruising haha.
