Rice water face wash review

I saw an actress on TV washing her face with rice water, and I thought it might brighten my skin, so I saved the water instead of throwing it away. But I had no idea that that water would spoil quickly. After washing my face with the rice water I'd saved for a few days, I got red spots on my face and it smelled so bad, it was a total disaster. My mom even scolded me for wasting rice, and I even got a back smash on my face. Haha. Later, I looked it up and found out that the first wash water can still contain pesticides and dust, so you should always throw it away and use the second or third wash water. Also, if you let the water sit for a few days like I did, it will spoil quickly, which is actually worse for your skin. I almost got a skin disease trying to see the whitening effect. Natural ingredients aren't always good. I just followed the instructions without doing my homework and ended up suffering. I think it's better to just buy a whitening ampoule and apply it instead. My skin is having a hard time today.
