But Ejiao is effective, but the effect will be slower. Direct supplementation of collagen is more effective. My mother is almost 50 years old. I ordered several boxes of collagen for her maintenance. Maybe the collagen I ordered is suitable for my mother's gastrointestinal absorption. She said that after drinking for a month, her skin felt much younger. No, she's still taking it. She also told me that other old ladies envy her, getting younger and better.
When I ordered it for my mother before, I took absorption into account, so I bought collagen which is easy to absorb. I ordered /FUV5Wiz here. You can learn more about it first. Maybe it will suit your mother.
