Hello, and thanks for using Petco Pet Education Center, formerly Petcoach. It’s difficult to tell for sure from the picture, but it seems the front part of Emma’s chin may be swollen. This is common in cats with feline acne. Sometimes it indicates a secondary infection, so I recommend having Emma seen by your vet. If needed, they will be able to prescribe antibiotics, and many cats improve using medicated wipes to keep the area clean. Make sure you use clean metal or ceramic bowls for Emma’s food and water, as some cats can get this as a reaction to plastic. Hope this helps!
