All You Need to Know About Melanin and Pigmentation
Hypopigmentation – Vitiligo and Albinism
When you think about pigmentation issues, dark skin patches and dark spots like melasma are usually the first things that come to mind. However, there are also some disorders characterized by white discoloration and depigmentation. The loss of skin color is called hypopigmentation. This happens when melanin production in the skin is reduced or stops completely. The most common hypopigmentation disorder is vitiligo, an autoimmune disease which is caused by a loss of melanocytes and leads to white patches of depigmented skin. Vitiligo is neither dangerous nor contagious, but many patients find the white patches aesthetically disturbing. It is unknown what exactly causes vitiligo. What is certain is that the condition is not curable at this point in time. However, there are several dermatology treatments available to improve vitiligo and prevent it from progressing. These treatment options include: Certain medications, phototherapy, laser therapy and transplanting melanocytes. Since stress and sun exposure can cause vitiligo to spread, it is essential to wear sunscreen with a high SPF and reduce your stress levels as well.
