10 days after Juvederm there is a reticular pattern after erythema subsided and sloughing, dry skin. Is it infected? (photos)

I would recommend you get the filler dissolved ASAP. you can always add more once the nose is back to the way its supposed to be. but for now its causing vascular compromise. I have treated some cases where the filler was not advised to be reversed by the injector and by the time I dissolved it the necrosis had advanced quite a bit. 

I recommend following up with your Doctor for a formal evaluation and treatment. If necessary, this can be removed with hyaluronidase. See an expert. Best, Dr. Emer

Although infection is certainly a possibility, a reticular pattern on the nose following the injection of a syringefull of filler should immediately ring the alarm bell of possible vascular compromise and appropriate action taken right away. At the earliest possible time following its development, it is medically wise to apply warm compresses to increase circulation; apply nitroglycerin paste and take aspirin (if no contraindication to its use) in order to maintain and promote circulation; massage the injected regions vigorously to manually break up the hyaluronic acid; and very importantly to inject hyaluronidase (either Vitrase or Hylenex) as soon as possible. In a confined area such as the nose, had infection been the cause, I would have expected more swelling and discomfort than you seem to have complained of. While I have no serious objection to the use of antibiotics and prednisone, I would have instead concentrated upon instituting asap the measures mentioned above in order to minimize the possibility of the development of necrosis and subsequent scar formation. I would strongly urge immediate reevaluation and treatment with hyaluronidase even at this stage. I wish you all the best.
