What is the difference between collagen and hyaluronic acid? Other unsafe factors

Collagen was a very popular beauty material in the past few years, while hyaluronic acid is an emerging beauty and skin care product in recent years. So which one is better? What is the difference between collagen and hyaluronic acid?

What is the difference between collagen and hyaluronic acid?

Collagen

Collagen is a biological macromolecular substance that has been frequently used in medical materials, cosmetics, and other applications in recent years. Collagen is generally extracted from some mammals, such as cattle, sheep and marine fish. However, due to the limitations of extraction technology, the activity of extracted collagen is often difficult to maintain for a long time. In addition, due to the trend of profit, many businesses will add some hormone substances to the collagen, which can easily cause side effects to patients or trigger some other unsafe factors.

In addition, there are many restrictions on collagen. Many people are not suitable for collagen treatment. For example, we generally do not recommend treatment for pregnant women, patients with major diseases or cancer patients, otherwise it is likely to cause some adverse effects or side effects. Therefore, with the improvement of medical aesthetics technology, collagen therapy has gradually faded out, and new hyaluronic acid has replaced collagen.

Hyaluronic acid

Hyaluronic acid is also called hyaluronic acid. The scientific name of hyaluronic acid is uronic acid, which is one of the important components of the dermis tissue. Hyaluronic acid molecules can carry more than 500 times their own amount of water and are recognized as the best natural moisturizing ingredient, so hyaluronic acid can be found in many cosmetics. However, this is liquid hyaluronic acid, not the large-molecule hyaluronic acid used for injection.

The injectable macromolecular hyaluronic acid is a product that is artificially manufactured to become a gel-like crystal. It can be injected subcutaneously to smooth out skin wrinkles or fine lines, and can be used to fill small facial depressions. The method of use is very simple, fast and effective. The effect can last for about 6-18 months.

In addition, hyaluronic acid is a substance that can produce immediate results and can be used for wrinkle removal, body shaping, etc. There are basically no side effects to injecting hyaluronic acid. Injecting hyaluronic acid is just like injecting the body's own components into the body. There is no need to worry about allergies, rejection and other problems. Hyaluronic acid can be treated as the body's own substance and will be metabolized over time.

Of course, hyaluronic acid also has its disadvantages, that is, it will be slowly metabolized and absorbed by the body, and cannot maintain long-term effects, and requires repeated injections. In fact, we all know that materials that can be metabolized by the body are the most reliable and safe, and the body's immune system is constantly changing. Current injection materials may not cause body rejection, but it does not mean that they will not cause body rejection many years later.

In general, collagen is inferior to hyaluronic acid in terms of both effectiveness and safety. Hyaluronic acid is known as the holy product in the current beauty industry and naturally has its unique advantages. The hyaluronic acid currently used in plastic surgery centers is the Swedish Restylane series, which has an exclusive patented particle technology, a firm structure, is conducive to shaping, is more stable and lasting, and does not require the addition of a large number of links that may be repulsive.
