Who is more prone to acne, southerners or northerners?

The south is hot and humid. Summer is the longest all year round, and it sweats a lot. I often see a lot of pimples on my face in the street, alas ~ ~ ~

When the climate in the north is dry, it is not easy to grow acne.

But northerners will get some acne if they live in the south for a long time.
