Master, Dr. Nguyen Phuong Thao, Department of Dermatology – Skin Aesthetics, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, said that when the climate is hot, the temperature and humidity are high, the skin will sweat a lot. than. In addition, the density of the sebaceous glands in the back is very high, when the sebaceous gland activity increases, there is a risk of forming acne nodules.
In addition, in the summer, many people prioritize outdoor recreation and sports activities. Wearing tight clothing causes body friction, making the environment on the back wetter. Doctor Thao said, this is also a favorable condition to cause back acne.
Usually, back acne begins with non-inflammatory lesions, which are nodules. The disease progresses more seriously if not well controlled, from non-inflammatory lesions to inflammatory lesions such as pustules, papules, nodules, cysts.

As a result, the patient suffers from pain and self-deprecation and does not dare to wear open-back clothes. Some people after getting rid of acne also have keloid scars, causing psychological and aesthetic effects, making treatment more difficult.
To control this situation, doctor Phuong Thao recommends that patients should pay attention to properly care for the back skin that is often overlooked.
When bathing, the patient needs to choose a mild mild soap with active ingredients that eliminate the horny part of the back skin, remove sebum or have anti-inflammatory properties. For people with a lot of acne on their back, they can exfoliate 1-2 times a week.
In addition, it is necessary to clean bed sheets, pillowcases and towels regularly because this is a hiding place for many bacteria, especially acne-causing bacteria. People who sweat often need to change their clothes often to avoid causing moisture in the back area. Clothing materials should be absorbent and soft.
If the above measures are applied but do not improve or worsen, the patient needs to go to a dermatological examination for appropriate treatment with oral drugs, topical drugs, etc.
Doctor Thao recommends that patients should have a healthy lifestyle, drink a lot of water, eat a lot of green vegetables and fruits, limit fatty foods, to prevent recurrence of back acne when the sun is hot.
