In childhood, hyaluronic acid has a very rich content in the dermis of the human body, but as we age, the metabolism gradually slows down, and the hyaluronic acid content of the dermis is gradually decreasing. Therefore, the older you get, the higher the likelihood of dryness, aging, wrinkles and other skin problems. Candidates of any age can improve the condition of their skin with hyaluronic acid with very few side effects. Hyaluronic acid can eliminate static lines on the face, including fine lines under the eyes, crow’s feet, tear troughs, bags under the eyes, lines under the eyes, laugh lines, etc. It can also be used to modify the shape of the lips, nose reshaping and cheek augmentation. After hyaluronic acid injections, some people may experience an allergic reaction. Most candidates will also be left with pinholes at the injection site and may experience mild redness and swelling, but these usually disappear within a few days. Although hyaluronic acid is suitable for anyone who needs it, candidates need to have a detailed consultation at a regular plastic surgery clinic before having the injection. In addition, candidates who are in pregnancy or have serious underlying medical conditions such as heart disease should hold off on injections.
