I will look like you have the measles. Edema and Erythema will occur at each injection site so the treatment area will be covered with raised red bumps following the procedure. These bumps will start to reduce in size within a few hours and will usually be gone (or barely noticeable) by the next morning. Residual swelling may last longer in a few people rarely up to 3 or 4 days. Occa-sional small bruises are also possible.
