Skin pigmentation refers to the color of the skin, primarily determined by melanin production. While variations are normal, some changes may signal health issues. This guide explores the types, symptoms, causes, diagnosis, and treatments of skin pigmentation disorders.

b. Age Spots: Flat brown spots related to aging.
c. Melasma: Dark patches often seen in pregnant women.
2. Hypopigmentation
This is characterized by lighter patches due to reduced melanin. Notable types include:
a. Vitiligo: An autoimmune disorder causing white patches.
b. Albinism: A genetic condition with minimal melanin.
c. Post-Inflammatory Hypopigmentation: Lighter skin after injury or inflammation.

a. Discoloration or patches of lighter/darker skin.
b. Uneven skin tone.

2. Hormonal changes: Fluctuations in pregnancy or hormone therapy can cause melasma.
