Hi Hun basically high profile have more projection from the side so will look bigger from the side and are normally used in girls who have a small ribcage and low profile are a wider implant that gives a fuller wider look from the front used in girls with a wider ribcage like me.
If was to of had high they would leave me with a gap in between my boobs and be really pointy like madonnas cones haha if I wanted more projection I would have to go for a much larger implant, there is a picture somewhere maybe on here of how they look basically if you imagine both implants same size on the table together them the high one would be narrower and raised off the table more and the low one would be flatter but wider hope it makes sense Hun
