Everyone's physique is different, and how long it takes to take effect after collagen injection varies from person to person. Some people may need 1 to 3 days to get the results, while others may need a week to a month to get the results.

Collagen is usually injected into the wrinkled parts of the skin to regenerate the collagen at the bottom of the skin, and at the same time, it plays a role in supporting the skin, reducing skin sagging and making the facial skin smooth and delicate.

Appropriate amount of collagen should be injected. If a person's physique is well absorbed, it will have obvious effect in a week or so. If the physique is slowly absorbed, the time will also increase. It will take about a month to see the obvious effect.

After collagen is injected into the dermis, the skin may become red and swollen. With the passage of time, the swelling symptoms will be relieved after the body absorbs collagen. During this period, do not rub and squeeze the injection site.

Collagen needle can bring some benefits, but it still has side effects on human body. Some people may be allergic, and the price is relatively expensive, which is difficult for ordinary people to bear.

Collagen needles can be stored in the skin for about six months to 18 months. Because everyone's depth, location and living habits are different, the length of time will not be the same.

Collagen needle can not only improve the effect of dark circles, but also fade the wrinkles on the skin.
