What are these cobblestone lumps on my chin? How can it be permanently fixed? (photos)

I encourage you to visit with your surgeon for an evaluation as you mentioned having fat grafting in the past. If it is determined that the look that concerns you is from muscle activity then Botox provide improvement by softening that effect.

​Treatment for chin dimpling ("pebble chin" or "orange peel") is Botox injected into the mentalis muscle. This typically gives great improvement to the appearance of the chin. Results take about 1 to 2 weeks​. I suggest getting a formal evaluation with a board-certified cosmetic dermatologist. Best, Dr. Emer​

Hi! This is a very common question. The dimpling that you see when you smile is likely due to the muscles of your chin contracting and "dimpling" the attached overlying skin. This is best treated with a neuromodulator (botox, disport, etc) to soften muscle tone in that area. This is a very normal thing to observe and is likely not the result of your previous fat grafting surgery. Morpheus is a great instrument to help with skin tightening in areas with loose skin but won't help the dimpling that is seen as a result of muscle movement!
