I have some blocked pores/small slightly red blemishes on my chest and baby powder works great on them! Patting a bit of baby powder tones down redness and gets rid of the blemishes very quickly as well. I don’t know if this would have any effect on larger spots, but it works great on these small ones 🙂
Also a tip for girls: Baby powder is great for an irritated bikini line before/after hair removal.
I bought a great Johnson&Johnson medicated baby powder with Aloe Vera and something else in it when I was in America, it was lovely, but haven’t been able to find it here in Britain. I just get a cheap basic baby powder here and it works great as well.
