Barrier boost B3 serum

Been using the booster for a week. Remains oily on the skin for the first few minutes. After it is absorbed or the skin feels quite dry. Spreads easily. 3 drops, 2 times a day. I don't like the smell. Doesn't smell very fresh or fruity. A different scent might have been more pleasant. It does narrow the pores. All in all, a good effect, just not so good with lubrication/retraction

Yes, I got to test!! I think it's a pretty good serum but my sensitive skin didn't like it very much. It's a thick serum with a nice fine oblique pipette you it's a white serum, everywhere it certainly has potential provided you have skin that is not sensitive:)

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.
