Barrier boost B3 serum

I used this product for a week, at first I thought it was a nice serum, but after a week I noticed a rash on my face. I stopped for a week now and just did the same skincare routine as before, and my house is much better already. Unfortunately, I don't recommend this serum.

I was very curious about this product as I had heard a lot of good things about it. Unfortunately, I don't see any difference in the visibility of my pores and this product gives me just more impurities... I've only been using the product for two weeks so maybe this is a phase and my skin still needs to adapt but at the moment I would definitely not recommend the product... I'm going use the product for another two weeks to see if this makes a difference. The only positive change is that my face is less affected by a greasy T-zone. In addition, the recommended amount is 3 drops but I think this is a little too little so I use 4 drops. I do like the bottle and it came in a nice package.
