Voltaire (1694-1778) said "The art of medicine consists of amusing the patient while nature cures the disease."
If you are re-pigmenting naturally, as I have done, you'll know that nature takes her time. It's taken me 3 years but at least it's been faster than waiting for a wonder-drug!
If you are using a holistic, complementary or nutritional treatment, my advice is to give it plenty of time and try not to obsess over the expected results. My pigment started to come back without my even noticing at first because I was busy getting on with my life. I thought the mottled appearance of my skin was just a case of sunburn and peeling until I looked closely and realised it was hundreds of freckles!
My name is Caroline.
