What should I check first before getting a treatment for blemishes? I'm not sure which procedure is right for me!!

Since I started taking care of my skin, I've tried various products at home to get rid of blemishes, but honestly, I've found there are limits. I've tried whitening ampoules and I'm diligently using sunscreen, but it seems difficult to get rid of blemishes that have already settled in just with home care.

I am just starting to look into blemish treatments, and I’m not sure what to check first. I’ve heard that there are laser-based and toning types of treatments; I’m wondering if the method varies depending on the location or color of the blemishes, or if it is determined during the consultation. I’ve also seen comments saying that pigmentation might temporarily increase after the treatment, and I’m worried if that is a normal reaction.

This is my first time ever visiting a dermatologist, so I’m completely clueless about what I need to know. If anyone has had treatments for blemishes, it would be really helpful if you could tell me how you first started!
