I have been using your products daily at night its no daubt a good product in a very affordable range and definitely recommend it to other i had pores and black heads on my face although i haven't seen a huge difference in blackheads with salicylic acid serum but still a little improvement is enough for me as i have too much stubborn black heads on my nose but yeah my pores have shrinken with niacinamide serum maybe if i continues using it will see more good results but yes i am satisfied with your product....
