Pores are coarse mainly because the skin is short of water, the cells are shriveled and contracted, the gaps between cells will become larger, and the pores will also become larger, so the first thing to make pores coarse is to replenish water. It is best to use pure dew to replenish water, because it is pure distilled, because toner contains chemical additives such as surfactants, and long-term use will make pores coarse. It doesn't really matter. If you have to change it, Oprah Lavender Pure Dew is acceptable, and it is better to match Oprah Lavender Essential Oil. I used to have big pores and rough feelings, hehe, now my skin is better than before.
