The injectable dermal fillers, which can be either synthetic or natural, are injected under the skin to restore volume, shape, contour, and reduce wrinkles. Hyaluronic acid is the most commonly used filler for wrinkles. The body naturally produces hyaluronic acid (HA). HA is a sugar that acts as a cushioning agent and provides nutrients to the skin. Healthy skin is rich in HA. However, factors such as aging and sunlight exposure can reduce the amount of HA. This causes skin to lose its structure and volume. The most effective hyaluronic acid treatments are for improving the appearance and texture of nasolabial lines, which run along the sides of your face from the corner of your mouth to the base of your nose. The skin is restored volume and wrinkles are smoothed away with dermal fillers. Dermal fillers can immediately be seen after an injection. Any swelling or bruising that may occur should recede within a few days. The results can last anywhere from 6 to 9 months to a year in certain cases. Injectable dermal filler results can vary, and the correction may be temporary. To achieve optimal wrinkle and fold correction, you may need to apply supplementary 'touch-up' treatments.
