What is the efficacy of this NMN beauty capsule of Bairuijian?

Meiji capsule is mainly used for whitening, anti-wrinkle and anti-aging. You can try it if you want to fight aging, but I recommend the female model of Gene Harbor, because I have used this model? I think the effect is not bad. It also contains NMN and whitening ingredients, which has a better effect on the skin. Sleep has also improved after using it. I was a little dizzy, but I won't now. I think it's good.
