My chin is bumpy T_T

hello.

The rest of my face is smooth and dry, but my chin is bumpy, so I'm worried.

After washing my face, I spray Isoi Cica and pat it on -> Isoi Blemish Serum -> Isoi Jang Su Jin Cream -> and finally apply Isoi Sun Cream.

For my bed cleansing routine, I use Witch Factory oil and Hansalim Chlorella Body Bar.

How can I make my jawline smooth?

Did I wash my face incorrectly?

I look forward to your help. Please make sure to let me know.
