I am worried about a pimple under my chin.

hello.

I am really worried because I keep getting pimples under my chin lately. At first, there was only one, so I didn't think much of it, but the number is gradually increasing, and they even hurt when I touch them, so I am concerned. I have been washing my face thoroughly and switching to gentle skincare products, but there hasn't been any significant change.

I am curious about the cause, whether it might be a hormonal issue or due to lifestyle habits. Please advise if there are any effective management or treatment methods. Also, please recommend products that are good for this type of skin. If you have seen results with any products, please let me know.
