Hyaluronic acid is a filler widely used in the field of aesthetics. It can help improve skin elasticity and moisture content, reducing the appearance of fine lines and wrinkles. The effects of hyaluronic acid injections are typically not permanent and usually last from 6 to 18 months.
The molecular weight of hyaluronic acid is an important factor determining its duration of effect. Generally, low molecular weight hyaluronic acid is primarily used for moisturizing and has a relatively shorter duration, typically around 6 months; medium molecular weight hyaluronic acid is suitable for filling wrinkles and soft tissues, with a slightly longer duration of 9 to 12 months; and high molecular weight hyaluronic acid is often used for shaping, such as rhinoplasty and chin augmentation, offering the longest duration, lasting from 12 to 18 months. Additionally, individual metabolic rates and post-treatment care can also influence the duration of hyaluronic acid effects.
To ensure better results and longevity of hyaluronic acid injections, it is recommended to choose experienced and qualified physicians for the procedure and to use high-quality hyaluronic acid products. After injection, following the physician's instructions for proper post-treatment care, such as avoiding touching or massaging the treated area, can also help maintain the effects.
