Does hyaluronic acid injection require refrigeration?

　　The hyaluronic acid injection is a non-surgical skin beautification treatment that primarily delivers nutrients such as hyaluronic acid, vitamins, and amino acids directly into the deeper layers of the skin using micro-needles, aiming to hydrate, moisturize, brighten skin tone, and improve skin texture. The reference price for hyaluronic acid injections generally ranges from 2000 to 4000 yuan per session, with visible improvements typically noticeable within one to two weeks after injection. Normally, hyaluronic acid injections need to be refrigerated during storage. Detailed explanations are as follows:

　　Hyaluronic acid injections contain various nutrients, such as hyaluronic acid and collagen, which can easily degrade in high temperatures, thus affecting the treatment effectiveness. Refrigeration can slow down the degradation of these components and maintain the quality of the hyaluronic acid injection. Additionally, refrigeration can reduce the risk of microbial contamination and extend the shelf life of the hyaluronic acid injection.

　　If hyaluronic acid injections are stored at room temperature for too long, they may become ineffective and fail to achieve the desired beautification results after use. They may even increase the risk of adverse reactions such as allergies and infections. Before using hyaluronic acid injections, they should be removed from the refrigerator and brought to room temperature before injection to avoid local discomfort. However, hyaluronic acid injections are not recommended during menstruation, pregnancy, or lactation, to prevent any adverse effects on the fetus or infant.

　　Different products may have different storage conditions, so it is recommended to carefully read the product instructions or consult a professional before use.
