How long does it take for the initial lumps to disappear after fat transfer to the face?

I’m not talking about the calcified necrotic fibrous lumps that can be the eventual result of a bad transfer. I mean the firm lumps that can be felt inside the soft edema during the first weeks after the procedure. Quote from Dr. Huang’s website (20 years of fat transfer experience): lots of swelling and bruising and lumps and bumps. Thank you.
