Although Psoriasis and Vitiligo are both conditions that cause alterations to the skin, there are many differences in the causes and treatments for each.
Psoriasis affects approximately three percent of the world’s population and can be caused by a combination of genetic factors and external triggers, such as stress or injury to the skin.
Vitiligo affects about one percent of the world’s population and approximately 1.5 million people in the United States. There is no definitive cause of Vitiligo although many experts believe it is an autoimmune disorder.
Psoriasis is caused by the quick growth of skin cells. Under normal conditions, skin cells grow and fall off but when a person has Psoriasis, the skin cells grow very rapidly but don’t fall off, causing them to build up in places on the body.
Vitiligo is a discoloration of the skin that can happen in small patches or can cover large portions of a person’s body.
