There are a few ways to remove double chin in Photoshop. The first way is to use the Clone Stamp tool. This tool creates a copy of the object you are working on, and then you can change the properties of the copy. The second way is to use the Curl command. This command will make your chin look more round. The third way is to use the Levels command. This command will adjust the brightness and saturation of your chin. The fourth way is to use the Gaussian Blur tool. This tool will blur your chin in a circular pattern.
