@lorrainechavez, I just now came upon your question about vitiligo as I was scrolling thru discussions. I am sorry that it has taken me this long to reply.
I have vitiligo on my skin - patches of nonpigmented skin that do not tan. Vitiligo is an autoimmune condition. It occurs when your immune system attacks the pigment cells in your skin. I wear sunscreen and avoid over exposure to sun. The areas, to my understanding are more susceptible to skin cancer.
The areas of my depigmentation developed slowly over many years. The skin has the same texture as my pigmented skin, and it is not raised, nor does it itch or flake. Just a very light colored patches scattered here and there.
Vitiligo Is a cosmetic condition. However since it is an autoimmune condition, it can be a hint for the doctor of other possible autoimmune conditions.
I have no medical background except for my own experience. I am willing to share what I know if you have any questions.
