How long can the effects of hyaluronic acid injection last? Analysis of the latest research in 2025

Hyaluronic acid injection is one of the most popular non-surgical cosmetic methods in the beauty industry. It can effectively improve facial wrinkles, nasolabial folds, eye bags and other problems. However, one of the most important questions many people are concerned about when receiving hyaluronic acid injection is: how long can the effect last? In 2025, the duration of the effect of hyaluronic acid injection is still the focus of many consumers. This article will give you a detailed analysis of the duration of the effect of hyaluronic acid injection and the influencing factors.

1. The working principle of hyaluronic acid injection

Hyaluronic acid (HA) is a substance naturally present in the skin that can effectively retain moisture and promote skin lubrication and elasticity. By injecting HA into the lower layer of the skin, wrinkles and depressions can be filled, and the three-dimensional sense of the face can be enhanced, making the skin look smoother and firmer.

2. Duration of hyaluronic acid filling effect

The effect of hyaluronic acid filling can generally last from 6 months to 2 years. Its duration is affected by the following factors:

Types of hyaluronic acid : Different types of hyaluronic acid vary in molecular size and concentration, which affects how quickly it is absorbed into the body. Higher concentrations of hyaluronic acid generally have longer-lasting effects.
Injection site : The duration of the effects of hyaluronic acid injection varies depending on the area where it is injected. For example, the effects of softer areas of the face (such as around the eyes) may be relatively short-lived, while the effects of firmer areas (such as the chin) may be longer-lasting.
Personal metabolism : Everyone’s metabolic rate is different. For people with faster metabolism, the effects of hyaluronic acid may fade faster.
Lifestyle habits : Smoking, excessive sun exposure and irregular skin care habits will accelerate the decomposition of hyaluronic acid, resulting in a shorter duration of effect.

3. How to prolong the effect of hyaluronic acid filling?

Maintaining good skin care habits : using moisturizing products regularly and protecting the skin from UV damage can prolong the effects of hyaluronic acid.
Avoid frequent facial expression movements : Excessive facial movements, such as excessive smiling, frowning, etc., will accelerate the absorption of hyaluronic acid.
Regular supplemental treatments : If you want to maintain the effect for a long time, you can perform supplemental injections when the hyaluronic acid filling effect decreases.

4. Safety and side effects of hyaluronic acid filling

Hyaluronic acid fillers are non-surgical cosmetic procedures with relatively low risks. Common side effects include short-term swelling, bruising, and mild pain at the injection site, which usually disappear within a few days. Choosing an experienced professional doctor to perform the injection can minimize side effects.

Summary :

How long hyaluronic acid fillers last varies depending on a number of factors. With proper care and supplemental treatments, you can prolong the effects of fillers and make your facial contours more three-dimensional and youthful. To ensure long-lasting results, it is important to choose a regular medical institution and a professional physician for treatment.
