Scarring is always a potential complication after Mohs and reconstructive surgery, and based on the photo it looks like an extensive amount of work was done. When a skin flap is used for a surgical repair, additional swelling and "pin-cushioning" can add to the stiffness of the skin, making it appear lumpy. At six weeks out there is still a lot of healing to do. Steroid injections and massage can significantly reduce scar tissue and make the skin much softer and more pliable, which can help flatten out the scar too. Often a series of injections can be required to get the best effect. It can take the skin up to 6 months to heal completely, especially over the lip and into the nose creases where swelling can persist long after surgery. I would recommend you follow-up with your surgeon to determine what steps might be best for you.
