Sun-Induced Pigmentation (Hyperpigmentation)
Definition: Sun-induced pigmentation refers to the development of dark spots or patches on the skin due to excess melanin production triggered by UV exposure.
Cause: UV rays cause melanocytes (pigment-producing cells) to produce excess melanin, leading to hyperpigmentation.
Types:
- Solar Lentigines (Sun Spots): Flat, dark spots that develop on sun-exposed areas like the face, hands, and arms.
- Melasma: Larger, patchy areas of hyperpigmentation often seen on the cheeks, forehead, and upper lip.
Protection Before the Cause: - Apply sunscreen daily to prevent excess melanin production.
- Wear wide-brimmed hats and UV-protective sunglasses.
Cure After the Cause: - Use skin-brightening creams with ingredients like vitamin C or hydroquinone to fade dark spots.
- Laser treatments or chemical peels can help reduce pigmentation.
Conclusion: Sun-induced pigmentation is common, but with diligent sun protection and skincare, its effects can be minimized and treated.
