Can you use Silikon-1000 for an alternative to filler for volume in eyebrow area or is filler if done right safe now? (Photo)

I want to achieve a more predominant browbone ridge by adding filler.I went to a verified plastic surgeon for a consultation (I've done my research).In order to do that they need to inject filler in glabella, eyebrow,and part of my top nose.Those are the most risky areas for filler and serious complications if things go wrong.They said they are 99.9% sure it will be okay. Is it still to risky, should I worry?Could I use Silikon-1000 as alternative.I saw how this is safer than filler,is it legit?
