I saw it on YouTube and tried a grain pack.

I heard natural face masks are good, so I bought some job's tears powder and tried making one. My skin seems a bit brighter, but I almost clogged the sink and was completely exhausted peeling off the powder from every nook and cranny of my face. ㅠㅠ I guess buying sheet masks is the easiest way. Don't go through the trouble I did; just stick to ready-made products.
