Hydrophilic fillers such as hyaluronic acid will gradually be absorbed by the human body over time, usually between 4 to 6 months. This is considered extremely safe by many plastic surgeons. "If you are not satisfied after injection, it can be restored after a period of time, with no damage to the body, because the material itself is a component of the skin, and will be discharged through metabolism," Liu Feng pointed out. However, for this reason, hyaluronic acid filling has a "time limit". According to Luo Shengkang's introduction, the validity period of the currently approved Restylane is about 4-6 months, and then it will return to its original state. According to relevant experts, although the national approval is for nasolabial groove filling, clinical practice has extended to other facial wrinkles such as forehead and eyebrow wrinkles (川字纹) due to the same principle.
As for the use of hyaluronic acid in shaping (such as nose augmentation, lip enhancement), Luo Shengkang said that there are many types of hyaluronic acid, and their "adhesion" degrees are different. The viscosity of Restylane is relatively low, mainly used for wrinkle smoothing; there are also other products (such as Perlane), which have been processed through some refining techniques, increasing their density and purity, with higher viscosity, mainly used for shaping, and its effectiveness will last longer, but such products are not yet approved at present.
It is understood that there are currently more than ten types of injectable hyaluronic acid, such as Restylane, Fineline, Perlane, SUB-Q, etc., mainly produced by European and American companies, including about four or five hyaluronic acid products including Restylane that have passed FDA certification in the United States.

Aesthetic seekers must be cautious in choosing products and hospitals. Although hyaluronic acid is favored by plastic surgeons because it can be absorbed by the human body, there are still certain risks in its use. According to experts, the hospital recently treated an aesthetic seeker who suffered from skin necrosis due to hyaluronic acid injection. "This is mainly due to the injection technique problem, because hyaluronic acid is a dermal filler, if the doctor injects too shallowly, it will lead to skin necrosis," he pointed out that the operation threshold for injection cosmetic procedures is low, and many unqualified personnel with low skills are operating illegally, so aesthetic seekers should choose carefully.
On the other hand, on the database of the National Food and Drug Administration, the use of each product must be transparent. If serious safety problems occur, they should be reported to relevant departments in accordance with the relevant adverse reaction monitoring regulations. When the product is re-registered, it should submit an evaluation report on all adverse events caused by the use of the product. For this, many plastic surgery experts believe that these regulations are conducive to safeguarding the interests of aesthetic seekers. Luo Shengkang introduced that currently only one product has been approved by SFDA, but there are no less than 10 kinds of hyaluronic acid filling products on the market, among which there may be counterfeit products, even more worrying is that there may be products diluted with Okinawa, or products made with hyaluronic acid used in industry.
Previously, whether in school or in the office, I was always called 'Snow White'. My skin has always been envied by others, and many friends like to pinch my cheeks.
Time really doesn't wait for anyone. Since having my baby, I feel that my skin has become terrible, yellowish and dull, with no luster at all, looking like I've aged several years. Colleagues no longer call me 'Snow White'. I feel like I can't hold my head up in front of colleagues, wishing to quit my job and stay home every day. At that time, I basically didn't dare to go out, afraid of meeting acquaintances, and large sunglasses became my daily travel essentials. Previously, with fair skin, I bought a lot of beautiful red clothes, but now I don't dare to wear them anymore, as wearing them makes me look even darker and uglier. Later, I would buy whatever my friends recommended, spending quite a bit of money, but in the end, I couldn't find a product that truly solved my skin problems and suited me.

Once, when I went out to eat with our company president Mr. Wang, I didn't pay much attention before, but this time I noticed that President Wang is already a mother of a 7-year-old child, yet her skin is still so tender, white, and elastic. So I couldn't help but ask, "What kind of skincare products do you use, Sister Wang? The effect is really good! Can you give me some advice?" President Wang smiled and said, "Don't you know? Then you're out of date. I bought Nata Whitening Tea on Letu Fashion Network. I saw many young people using it, so I bought it."
