Skin Pigmentation |
| |
Skin pigmentation refers to changes in skin color caused by variations in melanin production. The most common issues are hyperpigmentation (dark patches) and hypopigmentation (light patches), which can result from genetics, sun exposure, hormonal changes, inflammation, or certain medical conditions. Treatments range from topical creams to advanced procedures like chemical peels and laser therapy. |

Types of Pigmentation Disorders

Common Causes
-
Genetics: Inherited melanin levels determine baseline skin tone.
-
Sun Exposure: UV rays stimulate melanin production, leading to tanning or dark spots.
-
Hormonal Changes: Pregnancy, contraceptives, or thyroid disorders can trigger melasma.
-
Inflammation/Injury: Acne, burns, or cuts may leave dark marks (post-inflammatory hyperpigmentation).
-
Medications: Some antibiotics, chemotherapy drugs, and birth control pills affect pigmentation.

Risks & Considerations
-
Sun sensitivity: Treatments like peels and lasers increase vulnerability to UV damage.
-
Skin tone differences: Darker skin tones may risk post-treatment hyperpigmentation.
-
Recurrence: Melasma and post-inflammatory pigmentation often return without maintenance.
-
Medical evaluation: Sudden or widespread pigmentation changes may signal underlying conditions (thyroid disease, Addison’s disease, autoimmune disorders).
