Pore Minimizing 21 Serum

best pore minimizing serum, my sister has been using this for 4 weeks now, the results are good so far

I have stubborn open pores, so I tried this one and am amazed at the results!
I have been using it not for long and still my pores have visibly reduced.
I am noticing that even my skin texture has been improving!
I am also trying out their other products.
Thanks a lot, TIAM!
