Is it possible to treat large and small age spots, spots, and blemishes on the arm?

A patch that looks like freckles or age spots has spread across both arms.

During the 2015 MERS outbreak, we closed the hospital. So, I thought I had nothing to do, and I worked in the field all day in the scorching June sun, and I immediately got it.

Even though I am wearing long-sleeved clothes, I look like this.

I was surprised, but I was busy, so I went to the dermatologist around 2019, and they didn't tell me to come back.

Other skin is fairly clear, but only my arms are dark and dirty, making it hard to show my arms.

Is laser treatment possible?

Recently, perhaps because of aging, small spots have started to appear on my right calf and ankle.

I need to get an accurate diagnosis to know for sure.

There is also a small skin tag in my armpit, and it bothers me.

If possible, I hope you undergo all the procedures and become clean.
