Risks of an improperly performed dermal<unk>  procedure commonly include bruising, redness, pain or itching. Less commonly, there may be infections or allergic reactions, which may cause scarring and lumps that may require surgical correction. More rarely, serious adverse effects such as blindness due to retrograde (opposite the direction of normal blood flow) embolization into the ophthalmic and retinal arteries can occur. Delayed skin necrosis can also occur as a complication of embolization. Embolic complications are more frequently seen when autologous fat is used as a<unk> , followed by hyaluronic acid. Though rare, when vision loss does occur, it is usually permanent.
