I have various questions regarding blemish treatments, such as the cost.

I am curious about the types of treatments available for blemishes.
Having gone through all sorts of skin issues throughout my life, my skin feels a bit dirty. I really envy people with fair skin... but I also really envy those with clear, blemish-free skin.
I sometimes wonder what it would be like if those marks disappeared through blemish treatments.
Does the effect of blemish removal treatment last? I am curious if it requires consistent sessions, similar to melasma removal. I am not sure what specific procedures are available, but I wonder if it will be painful... and if the blemishes can really be removed cleanly. Of course, I am also curious about the cost of the treatment. If there are various procedures available, I would appreciate it if you could let me know which one is the most reasonable in terms of both duration and cost.
I wish I could get rid of wrinkles, blemishes, or at least one of them from my face. ^^;;;
