How to eliminate acne scars and post-inflammatory hyperpigmentation
Generally, acne scars and post-inflammatory hyperpigmentation may be related to improper skincare habits, decreased natural skin repair ability, endocrine disorders, contact dermatitis, and acne. Patients can wait for the pigmentation to fade through methods such as avoiding squeezing pimples, maintaining a balanced diet, and medication. It is recommended to visit a hospital to determine the cause and follow medical advice for treatment. Detailed analysis is as follows:

1. Improper skincare habits: Frequently squeezing pimples or using overly harsh skincare products may worsen acne scars and pigmentation. Avoid squeezing pimples and choose gentle skincare products, especially those designed for sensitive skin.
2. Decreased natural skin repair ability: As one ages, the skin's natural repair capacity gradually diminishes, slowing the recovery of acne scars and pigmentation. It is recommended to maintain a regular sleep schedule, eat a balanced diet, and consume more foods rich in vitamin C and E.
3. Endocrine disorders: Fluctuations in hormone levels, especially excess androgens, can exacerbate acne, leading to scars and pigmentation. Patients should promptly follow medical instructions to treat with medications such as Zhenyuan tablets, Xiaoyao pills, and spironolactone tablets.
4. Contact dermatitis: When the immune system is abnormal, contact dermatitis may occur, releasing inflammatory mediators that worsen skin inflammation and lead to acne scars and pigmentation. It is recommended that patients use medications such as loratadine tablets, mupirocin ointment, and clobetasol propionate cream under a doctor's guidance to alleviate symptoms.
5. Acne: Acne is a common skin condition characterized by chronic inflammation of the pilosebaceous units. After healing, it often leaves behind pigmentation and scars, and may also present with erythema, pustules, and nodules. Patients should use medications such as adapalene gel, asiaticoside cream, and metronidazole gel as recommended by a doctor to aid recovery.
In daily life, maintaining good living habits, such as sufficient sleep, balanced diet, and regular作息, can help improve skin condition and promote fading of acne marks.
