My chin and the tip of my jaw feel bumpy to the touch. What kind of treatment would be best?

Hello. I am contacting you because the skin around my chin feels particularly bumpy when I look in the mirror or wash my face. It doesn't appear as red bumps like acne, but the uneven texture is severe, and my makeup looks patchy, which is causing me stress. I would like to receive an accurate diagnosis to determine if this is due to excess sebum or comedones, or if it is keratosis pilaris or another skin issue. I am curious to know which procedures, such as extraction, scaling, or laser treatments, are generally effective for smoothing out this bumpy skin texture on my chin. I would appreciate it if you could also provide information on the treatment frequency and frequency, whether it interferes with daily life, and the approximate cost. I know you are busy, but I would be very grateful for a detailed response!
