The charity works with people affected by vitiligo, the skin disorder that causes patches of skin to lose colour.
The agency is launching an awareness campaign in early July, particularly targeting young women in their late teens and early twenties.
The charity wants to bust myths around the condition. As well as providing case studies to women's magazines and broadcast media, it will place virals on social networking sites.
Dr Linda Papadopoulos is to be spokesperson for the campaign alongside other celebrities including Spartan from Sky One's Gladiators.
