As a start, what causes acne on the back?
According to dermatologist David Lortscher (via Byrdie), the causes of acne are the same as those caused by acne in other countries. In other words, genetics, hormonal changes, stress and lifestyle are important.
Acne can occur in the footwear area, but in this case it is advisable to change the material of the underwear. Cotton materials are advised.
As for the sweat caused by exercise, it is not a risk, but you should definitely wash after physical activity, because sweat helps to multiply germs.
In other words, the first step to eliminating acne on the back is to do the same as with facial acne: Cleansing and a healthy diet.
How can they be treated differently?
In addition to cleansing and a balanced diet, you can use products that contain salicylic acid, because it prevents and at the same time treats clogged pores.
