Following the success of the other thread on white teeth I was wondering how exactly one gets very clear facial skin. This thread is not meant to compare different products (although you can mention ones that work well) but more of the whole process. I know exfoliation and cleansing creams are a basic start but rarely do they solve the problem completely. Are there any foods one should avoid? I know excess salt results in puffiness and bags under your eyes. So any advice here is appreciated.
