enlarged pores的原理，看这个。哪个词没听懂的，点进去，里面有interactive transcript可以看字幕
好好先把exfoliation做好
最便宜的方法做exfoliation和缩小pore：洗面奶里加点盐，好好撮一撮，洗完后再用baking soda和水再洗一遍，大概一
个teaspoon那么多baking soda就可以，加点水做成paste，脸上抹抹，然后用冷水rinse，完了以后毛孔小小的～
如果皮肤敏感，用盐可能会刺激，尤其是如果脸上有open scar例如痘痘，上盐会疼，可以忍受就是了 |

I have huge pores on my nose, and i kind of give up to treat the pores after
trying so many different skincare products over the years (12 years and
more). Now, as being mid 30 years of age female with a child, my major
skincare concern moves to anti aging : ) |
