Beauty Hack: Plain Yoghurt If you accidentally burned yourself on your hair straightener or curling iron, make your way to the fridge and find your supply of plain yoghurt ($4). Put a dollop on the affected area, and leave it on for 10 minutes while the probiotics in the yoghurt get to work rebuilding the skin's barrier and the coolness calms the pain.
