Steroids Injections to Reduce Swelling After Facelift?

It’s not unusual for patients to experience significant
swelling following facelift surgery. In
the vast majority of patients, swelling resolves with the passage of time. For this reason, steroid injections aren’t
usually indicated to treat this problem. Steroids
are occasionally indicated to treat adverse scarring in the late post-operative
period. Unfortunately, steroids may be associated with skin atrophy, scar
spread, hypopigmentation and redness. For these reasons, steroids should be used with caution when treating
adverse scarring following facelift surgery.

I do not perform steroid injections do reduce swelling.  At your point, it is not surprising that you may have some swelling or lumps.  Your surgeon should check to make sure there are no problems, but I would not rush into steroid injections.  They can cause thinning if the skin and atrophy of the underlying tissue.  

  I use steroid injections to treat scars after facelift surgery.  that said, at seven weeks your incisions are still going through normal healing and a normal remolding process.  I think you should wait longer and use scar cream conscientiously before considering steroid injections.
