Is there a way to smooth out uneven skin?

Hello. My skin texture is uneven due to poor skin care, and my face is not smooth due to bumps and raised areas.
Even if it looks fine from a distance, when viewed up close or under light, the skin surface appears uneven and the uneven areas stand out.

I'm wondering if there are any treatments that are effective in improving these uneven areas.
If so, please also share the number of treatments and recommended cycle information that is suitable for my skin condition.

Also, is it possible to know whether the bumps will not reappear after the procedure?

I want to have smooth, egg-like skin like other people.
