How can I remove acne scars?

Generally speaking, post-inflammatory hyperpigmentation (dark spots left by pimples) may be related to factors such as skin type, age, sun exposure, improper squeezing, and acne. Patients can wait for the dark spots to fade through enhanced daily skin cleansing, avoiding excessive intake of high-sugar foods, avoiding direct sunlight, refraining from squeezing pimples manually, and medical treatments. It is recommended to visit a hospital to determine the specific cause and follow medical advice for treatment. Detailed analysis is as follows:

1. Skin Type: Oily and combination skin types tend to produce excessive sebum, which can easily clog pores, trigger inflammation, and lead to post-inflammatory hyperpigmentation, which is a primary cause of acne marks. In daily skincare, choose oil-controlling and anti-inflammatory products, perform regular deep-cleansing mask treatments, and maintain clean skin.

2. Age Factors: During puberty, increased levels of androgens in the body may cause overactive sebaceous glands, leading to acne and subsequently leaving acne marks and scars. Maintain good personal hygiene habits and avoid excessive intake of high-sugar and high-fat foods.

3. Sun Exposure: Ultraviolet radiation activates melanocytes, worsening pigmentation. It is recommended to perform daily sun protection, use sunscreen, and avoid direct sunlight exposure.

4. Improper Squeezing: Improper squeezing causes skin tissue damage, exacerbates inflammatory responses, and leads to acne marks. Avoid squeezing pimples manually, maintain hand hygiene, and use skincare products with soothing and repairing functions.

5. Acne: When acne occurs, skin tissue is damaged, inflammatory mediators are released, and melanocyte activity increases, leading to localized pigmentation, often accompanied by erythema, pustules, and nodules. Patients should use medications such as adapalene gel, septilin cream, and metronidazole gel under the guidance of a physician to aid recovery.

In daily life, maintaining good living habits, such as sufficient sleep, balanced diet, and regular作息 (作息 refers to daily routines), can help improve skin condition and promote the fading of acne marks.
