One of the biggest advantages of hyapen fillers is their ability to provide natural-looking results. Hyaluronic acid is a substance that naturally occurs in the body, so it blends in seamlessly with your skin. This means that you can achieve a more youthful appearance without looking like you've had work done. Hyapen fillers are also customizable, meaning we can adjust the amount of filler used to achieve the results you want. While the effects of hyapen fillers aren't permanent, they are long-lasting. On average, hyaluronic acid fillers can last anywhere from 6 to 12 months. Touchups are recommended for better retention.
