To help determine if you are allergic to the substance, your surgeon will perform an allergy skin test about a month before the procedure. After the test is performed, the test site should be watched carefully for three or four weeks, or as long as your surgeon advises. Any sign of redness, itching, swelling or other occurrences at the test site should be reported to your surgeon. Risks not necessarily related to allergies include infection, abscesses, open sores, skin peeling, scarring and lumpiness, which may persist over the treated area. Reports of these problems are very rare.
