I received Hico treatment at a dermatologist, which lasts for about a year. I heard that HICO is a procedure that involves inserting thread into the bridge of the nose and filling it with filler. They say it lasts longer than regular fillers, but it's been 4 months for me and it's almost gone. Perhaps because I often use my facial expression muscles and touch my nose often, the filler disappeared very quickly. Haha, if you do it like I did, the filler will disappear quickly!! Please be careful
