Is there many kinds of hyaluronic acid? In fact, hyaluronic acid can only be considered a general concept, and many beauty seekers ask me if hyaluronic acid is a panacea. Because we use hyaluronic acid for nose job and chin pad, we use hyaluronic acid eye drops for dry and red eyes, and we still use hyaluronic acid for hydration. Is hyaluronic acid really such an all-purpose miracle product? In fact, it is not, hyaluronic acid is just a name they collectively called, their actual composition is very different. To understand why hyaluronic acid is so versatile, you can simply divide hyaluronic acid into large molecule hyaluronic acid and small molecule hyaluronic acid, although this division is indeed a bit general, but basically reflects the basic form of hyaluronic acid. For example, the larger the molecular weight of hyaluronic acid, the harder it will be, and likewise its support will be stronger, easily topping up our chin, nose and other parts. But is the larger the molecule of hyaluronic acid the better? Obviously not, we want hyaluronic acid to be able to fully grasp the water and spread out on the skin to improve the condition of our skin and make it whiter and more delicate, so the hyaluronic acid we need at this time must be soft. Only soft hyaluronic acid can be smoothed out on the skin. Speaking of this I also think of a clinical case, which can also be said to be a bad thing done by the beauty salon. It is to mix the hyaluronic acid used for nose and chin augmentation as the hyaluronic acid used for hydrafacial injection into the hydrafacial machine, and give the candidate a superficial skin injection, resulting in the production of bumps on the face one by one, which do not even go down for half a year. Foreign body granuloma like this one is very troublesome to deal with clinically. So although they are all called hyaluronic acid, it is possible that the uses are not the same. There are thousands of hyaluronic acids, but the ingredients vary. Therefore, before injecting, candidates must find a doctor in a professional hospital, who can distinguish the nature of different hyaluronic acids and finally give targeted advice and use to the candidates.
