NMN

so I am on my skin care journey, and I thought well I need to also work from inside out, so I started looking at vitamins that could help with number of factors and I came across this NMN- I wasn’t sure if it would work and it is too soon to say as it’s only been about a week of taking them. I have noticed that my skin looks clearer, my fine lines look less prominent, however I don’t know if it’s this NMN or Beauty bays skin care-(started both same day) would recommend you try and see for yourself.
