The ordinary reactions. Bruising at entry points, swelling that peaks then settles, tenderness, and small palpable lumps while a gel distributes. The lip and the under-eye swell and bruise most visibly. These are expected, and they are what a review appointment looks at.
Vascular events. Gel entering or compressing a vessel is rare and urgent for either family. Blanching as the gel goes in, pain climbing instead of easing, a dusky mottled patch over the following hours, or any change in vision means telephoning the clinic in the same hour, on whatever day it happens.
Placement that fights the plane. A firm gel too close to the surface can leave a ridge or a grey cast; a soft gel buried deep gives up its shape. Most disappointment with fillers traces back to this mismatch, which is why the plane is decided before the product is.
Infection and delayed lumps. Spreading redness with heat, or a nodule appearing late, is assessed, never waited out. Previous injectable material in the same region is disclosed at consultation, because adding volume on top of an unknown complicates everything that follows.
The reversible part. Both families are hyaluronic acid, so both respond to a hyaluronidase injection where the director judges it appropriate. The enzyme does not separate the part of a result you disliked from the part you were happy with, and it is held at the clinic for use at the director's judgement, with whatever applies explained to you first.
Where the examination finds laxity instead of lost volume, we do not recommend either gel for it and say what would actually answer the complaint, usually something from the lifting and tightening category. Active infection over the area, pregnancy and breastfeeding postpone an appointment entirely, and blood-thinning medication or a bleeding disorder changes what you should expect and sometimes the plan itself.
