Causes of back acne! Surprisingly, it could be an electric blanket.

I saw a post like that on the internet.

Electric blankets stimulate the sebaceous glands on your back, so you get back acne easily.

Come to think of it, that's really true! Usually, you'd expect more acne in the summer because sebum production is more active, but it's the opposite for my back.

I really need to get through the winter well to get through the summer without scars. Anyway, that is why I only turned it on when it was really cold last winter, and I don't think I used it at all, and it definitely seems to have decreased. Of course, winter without an electric blanket is hard, though!
