Can hyaluronic acid injections remove acne marks?

　　The hyaluronic acid injection primarily delivers nutrients directly into the deeper layers of the skin via microneedling to hydrate, moisturize, and brighten the skin. The general reference price for a hyaluronic acid injection session ranges from 2000 to 6000 yuan, and visible improvements typically appear after 1 to 3 months. Hyaluronic acid injections may help reduce mild acne marks, but they are generally ineffective for more severe cases. It is recommended to seek timely medical advice and undergo treatment based on individual conditions.

　　Acne marks are mainly caused by post-inflammatory pigmentation or skin tissue damage, while the primary function of hyaluronic acid injections is hydration and nutritional supplementation, with limited effects on pigmentation or tissue repair. For superficial and mild acne marks, hyaluronic acid injections can improve overall skin condition, making acne marks less noticeable and providing some degree of removal.

　　However, for severe acne marks such as dark, raised marks or scars, hyaluronic acid injections have limited effectiveness and generally cannot completely remove them. More specialized treatments, such as laser therapy or chemical peels, may be required in such cases. After the injection, it is important to keep the skin clean and avoid using irritating cosmetics or skincare products to prevent infection.

　　In daily life, it is recommended to reduce sun exposure and avoid UV damage to the skin, which can加重 the skin's burden. If going outdoors is necessary, applying sunscreen or using an umbrella for shade is advised.
