For example, there is erythema on the back, which is neither painful nor itchy, and there is no response. There seems to be a few more recently, and I'm afraid it will continue to increase. Ask everyone what's going on first. because

Most of the acne on the back is caused by folliculitis. This is related to the exuberant secretion of fat from hair follicles on the back and the hygienic management of sheets.

1. Keep the sheets and close-fitting clothes clean. Because the back is in direct contact with these things. 2. If your acne is getting bigger and bigger, it is still serious.

3. The back is the reflection area of the lung, and lung heat or meridian obstruction can cause acne on the back. Usually you can eat more white heat-clearing foods, such as tremella, Sydney, lily and white raspberry. If you sweat too much, the clothes attached to your back will also breed bacteria. Just wash, change and clean.

5. The most important thing after taking a bath is to absorb the water on your body and dry it with a towel before wearing clothes, otherwise the clothes will breed bacteria if they are wet and stick to your back.

6. Skin allergy may also cause acne on the back. So find the source of allergies and avoid contact with the skin.
