What is the reason for the repeated growth of acne on the back

Repeated growth of acne on the back may be caused by excessive sebum secretion, abnormal keratinization of hair follicles, bacterial infections, fluctuations in hormone levels, and poor lifestyle habits. Acne, medically known as acne, is a chronic inflammatory disease of the hair follicle sebaceous gland unit.

1. Excessive sebum secretion

The sebaceous glands on the back are densely distributed, and when the sebaceous glands are overactive, they will secrete a large amount of oil. These oils mix with shed keratinocytes to form keratin plugs, which clog pores and form acne. High temperature environment and high sugar and high-fat diet can stimulate sebum secretion. Keeping the back clean and dry, using gentle shower gel can help reduce oil accumulation.

2. Abnormal keratinization of hair follicles

The metabolic disorder of keratinocytes at the hair follicle opening can lead to excessive accumulation of keratin. This abnormality can narrow the hair follicle ducts and affect the normal discharge of sebum. Lack of vitamin A and genetic factors may induce abnormal keratinization. Proper exfoliating care can improve this condition, but excessive friction and skin irritation should be avoided.

3. Bacterial infection

Propionibacterium acnes proliferates extensively in hypoxic hair follicles, decomposing sebum to produce free fatty acids. These substances can stimulate the hair follicle wall and trigger an inflammatory response, forming red papules or pustules. Sharing towels and unclean clothing may increase the risk of infection. It is important to change bed sheets and clothing in a timely manner and maintain personal hygiene.

4. Hormonal level fluctuations

During puberty, menstrual cycles, or increased stress, elevated levels of androgens can stimulate sebaceous gland hyperplasia. Endocrine disorders such as polycystic ovary syndrome can also lead to similar situations. This type of acne often recurs during the menstrual cycle. Adjusting daily routine and relieving stress can help improve symptoms.

5. Poor lifestyle habits

Long term wearing of non breathable clothing, lack of sleep, and imbalanced diet can all exacerbate back acne. Friction and sweat retention from tight clothing can irritate the skin, while a high sugar diet can promote inflammatory reactions. Choosing cotton clothing, ensuring adequate sleep, and a balanced diet can help prevent recurrence. For recurrent back acne, it is recommended to wear loose and breathable cotton clothing and avoid using greasy skincare products. Clean your back with warm water every day, but avoid excessive scrubbing. Reduce the intake of high sugar and high-fat foods in diet, and eat more fresh vegetables and fruits. If the symptoms continue to worsen or cysts and nodules appear, you should go to the dermatology department in time, and the doctor may prescribe retinoic acid cream, peroxybenzoyl gel or antibiotics for treatment. Maintaining a regular schedule and a positive mindset are equally important for improving skin condition.
