Hi everyone!

Recently (about 3-4 days ago) I went to a trip on the mountains and got exposed to sunlight for 6h+, but I didn't wore any sun protection at all and my arms a nice brown shade now.

But, some weird brown spots and pearly moles appeared on my right arm (one of the moles is on the palm of my hand, and has been at least 2 weeks).

I'm worried it might be skin cancer, what do you think? Should I go to a dermatologist ASAP?
