I have been using this for over 2 weeks and it really helps improve my skin texture. After toner step, I apply this liquid (2-3 times per week) and wait for about 20-30min. After 2 weeks, my skin is much brighter, the pores are obviously smaller, and blackhead also reduce significantly. The most important result that this product brings to me is that: it helps to unclog my pores, so that other following product in my skin-care step could do their work more effectively. Since, i only use it 2-3 times per week, so this bottle will last a long time. Definitely recommend if you have clogged pores and hidden acne under your skin.
