i doubt protein powder causes break-outs
My personal understanding that protein powder is not the cause of break-outs. I have a feeling that its best to avoid fatty food, as the oiliness comes out on the skin where dirt and bacteria can clog pores starting the break-outs. Break-outs are also caused by hormonal imbalances/changes often experienced during puberty. I believe they're also a side effect to taking steroids?- but i think it highly unlikely that protein powder is the source of acne.
