According to the Mayo Clinic, vitiligo occurs when pigment-producing cells (melanocytes) die or stop producing melanin — the pigment that gives your skin, hair and eyes color. There are some treatments that may restore color to the affected skin, but it does not prevent continued loss of skin color or a recurrence. Between the ages of 10 and 40, Denise masked her face and hands with a blanket of foundation and concealer to hide her vitiligo. I wore it every single day and I learnt how to perfect it so people who looked at me wouldn't even know I had it on.
