I have only been using

I have only been using this for a few weeks and have noticed improvements. I love the way it makes my skin look, hydrated and glowing. A little goes a long way. I layer this product on top of the snail mucin.

I am thrilled with this

I am thrilled with this Niacinimide serum and can’t believe how quickly it has benefited my skin. After just a couple of applications I noticed that my skin was clearer and smoother. It is perfect for my combination skin. I have tried several other products to improve my complexion but none have had the positive impact as this serum. I highly recommend it.

Be cautious

It started doing well, but I had to stop since it irritated my skin very badly. I tried to minimize it from every night to every other night, and now I’m down to once a week, but still irritates me. Had to stop it.
