Kiedy warto wykonać wampirzy lifting twarzy?

Lifting to zabieg najczęściej kojarzony z inwazyjną procedurą chirurgii plastycznej. Jednak można przeprowadzić go także bezinwazyjnie – wystarczy udać się do dobrego gabinetu medycyny estetycznej. Tam można wykonać zabieg wampirzego liftingu, który obecnie cieszy się bardzo dużym powodzeniem.
