Your question is a good one but the answer depends upon how you were given the steroids. Normally, steroids aren't used within the surgical area at the time of surgery due to delayed healing issues. Steroid injections AFTER surgery to localized areas of swelling or firmness, or into scar tissue, are not uncommon, can minimize the duration of localized swelling or scar tissue, and in experienced hands should have no adverse affect. If you've had steroids other than the intravenous dose nearly always given at the time of the survey or a short course of oral steroids, you'd best contact your doctor as to what specifically the steroids were used for, the desired benefit, and the potential for problems.
The effect of a steroid injection for scarring after a facelift can be felt and seen within days or weeks.Repeat injections are performed after the results of the first injection seem to have tapered.Generally, steroid injections are used to help a problem area of scarring or edema, so the results are intended to be beneficial and not damaging.Best wishes,Dr. Denkler
