How long does a single hyaluronic acid injection last?

Generally, the effect of a single hyaluronic acid injection can last for 3-6 months. The principle of hyaluronic acid injection involves using micro needle injection technology to precisely deliver nutrients such as hyaluronic acid and collagen into the dermis, achieving effects of hydration, moisturizing, skin quality improvement, and enhanced skin metabolism. The general reference price for hyaluronic acid injection is 400-1300 yuan per session, with visible improvements typically noticeable within 5-7 days. This procedure should be performed at a legitimate hospital. Detailed analysis is as follows:

If an individual's metabolic rate is faster, such as in younger populations, the active ingredients in the hyaluronic acid injection may be metabolized and broken down more quickly, resulting in a shorter duration of effect, lasting only about 3 months. Additionally, if the dosage or concentration of the injected hyaluronic acid is low, or if post-treatment care is improper—such as neglecting skin moisturizing and sun protection—the duration of the effect may also be shortened.

If an individual's metabolic rate is slower, such as in middle-aged and elderly populations, the body's metabolism of the hyaluronic acid injection components is relatively slower, allowing the effect to last longer—up to 6 months. At the same time, using high-dose, high-concentration hyaluronic acid injections and strictly following post-treatment care instructions, such as proper skin moisturizing and sun protection, can also help prolong the duration of the effect.

After the injection, it is important to keep the injection site clean and dry, avoiding contact with water to prevent infection. Additionally, one should avoid using irritating skincare products and cosmetics, and focus on skin moisturizing and sun protection.
