There are few complications and risks in nose fillers like other skin care procedures. If it’s administered by a qualified professional, then the chances of complications are low. Sometimes, it causes infection at the injection site because of improper sterilization and hygiene protocols to be followed and some allergic reactions also occur as few people are allergic to the filler material used. Sometimes even redness and swelling also occurs, which you shouldn’t have to worry about as it gets resolved within a few days. The severe complication that can occur is vascular, in which the filler is injected into the blood vessels unintentionally, which cause skin necrosis or other serious complication.
