Inquiries regarding melasma, freckles, moles, etc.

I have many blemishes, such as melasma, freckles, and various red spots. Do you use a laser to remove them?

Which season is appropriate for visiting a dermatologist for a consultation and removal, such as summer or winter?

My skin also has a lot of redness on my cheeks. Lately, my overall skin tone seems to have darkened. My under-eye area looks a bit darker, and when I look closely at melasma, there are small black spots that look like black dots on a cabbage.

While melasma and freckles are a problem, I also have some large moles on my face—I think there are at least 4 or 5 of them. Can these large moles be removed in one go with a laser, or will it need to be divided into several sessions?
