Initially you should start by doing it only for 1-2 mins because one might feel dizzy or nauseous, but with daily practice you will get used to it. Please find the link attached to get an idea about it: http://www.youtube.com/watch?v=1y3ZOCXEX98

My aunt had melasma. She started ding Kapalbhati pranayam and the melasma reduced within a few weeks and went away completely in a couple of months. In India, yoga master Ramdev Baba's style of doing kapalbhati Pranayam is the most popular. Here is the link to see how it is done:

If you do it, do write back in a month to let us all know if your melasma has faded. Good wishes! (I do kapalbhati everyday for other health benefits and like Ramdev Baba says, it seems to cure all problems.)

After I started doing kapalbhati pranayam, my migraines reduced, face glows. No more constipation (elimination is very good) and stomach has become flatter). I don't get colds either. Also, I steadily loose weight when I do this regularly.
I practice Kapalbhati Pranayam as taught by swami Ramdev. He says this pranayam is a cure-all. Here is a link to view how the pranayam is done: http://knowyoga.org/tiki-index.php?page=Kapal Bhati Pranayam
