Hyaluronic acid is a highly popular injectable cosmetic treatment. Injections can enhance facial contours, reduce wrinkles, and hydrate the skin. While effective, hyaluronic acid is gradually absorbed by the body, typically lasting 6-12 months.However, some individuals notice their hyaluronic acid injections wear off quickly. Why does this happen?
Constitution Factors
Thinner individuals tend to absorb hyaluronic acid faster than those with a fuller build. Additionally, metabolic rates vary by age, even when the same dosage is injected into the same area. As skin naturally contains less hyaluronic acid with age, the injected substance metabolizes more rapidly in older skin, resulting in shorter-lasting effects.
Faster Absorption on First Injection
Regardless of the individual, the initial injection is absorbed most rapidly. Higher-quality hyaluronic acid may last slightly longer, as it functions like moisture within the skin. When first introduced, skin cells quickly absorb this foreign substance.However, some notice their skin becomes plump and hydrated after hyaluronic acid treatment. Subsequent touch-up injections are absorbed less rapidly because absorption has a threshold—once a certain level is reached, further absorption ceases. Therefore, after several touch-ups, the duration of results extends.
Staying up late and drinking alcohol accelerate absorption
Those who stay up late or drink alcohol experience accelerated hyaluronic acid absorption. Alcohol boosts blood circulation, hastening its loss. Lack of sleep dehydrates the skin, leading to increased hyaluronic acid absorption. Similarly, dry, dehydrated skin absorbs hyaluronic acid more quickly. Therefore, drinking plenty of water after injections can help slightly prolong the effects.
Psychological Effect
Immediately after hyaluronic acid injection, the skin may feel firm with some swelling, creating an initial sense of satisfaction. Within one to two weeks, as the hyaluronic acid integrates with the skin, it softens to feel natural, like your own tissue. Once swelling subsides, many mistakenly believe the hyaluronic acid has been fully absorbed. This isn't the case—complete absorption doesn't occur instantly. It's important to view this objectively; the filler doesn't disappear rapidly after injection.
