Collagen can be taken on an empty stomach in the morning or about 3 hours before going to bed after dinner in the evening, and it is best to take it with VC.

Take VE together or take it with grape seeds, and the effect is better. Collagen is mainly aimed at the skin. After taking it, it is mainly manifested in whitening and moisturizing, removing spots and imprints, shrinking pores, removing dark circles and bags under eyes, removing wrinkles and firming skin. There are too many collagen brands now, so I suggest you choose a collagen brand with high popularity and good reputation, preferably sold online.

There is a collagen shopping guide network, and the collagen products recommended above are very popular in Taobao. I'll share that shopping guide network with you, and you can also refer to it.

I hope it helps you.

Hmm. How interesting
