What side effects does collagen beauty have? Who used collagen? Tell me about it?

I ate delicious fish collagen, which is the latest jelly-like fish collagen in China. It is not only delicious, easy to carry, but also effective. Made of Japanese deep-sea fish skin, it is pure, pollution-free and has no side effects. The molecular weight of collagen is below 1000 dalton, which can be completely absorbed by human body. With fruit juice, it is sweet and sour, and tastes good. Jelly is also very portable and can be eaten anytime and anywhere. Compared with similar products, the price is also relatively close to the people. After eating for a while, the effect is really good ~ the skin quality has improved ~ it is more shiny than before.
