Sun-Induced Pigmentation (Hyperpigmentation) vs. Actinic Keratosis
Similarities:
- Both conditions result from long-term sun exposure and are more common in individuals who spend a lot of time outdoors.
- They affect the outer layer of the skin and are more prevalent in older adults.
- Sunscreen and protective clothing are essential for preventing both conditions.
Differences:
- Sun-Induced Pigmentation (such as melasma or sun spots) is a cosmetic concern, where excess melanin is produced, leading to dark spots or patches on the skin.
- Actinic Keratosis is a precancerous lesion caused by sun damage that can progress to squamous cell carcinoma if left untreated.
- Pigmentation disorders are primarily treated with topical creams or laser therapy, while actinic keratosis may require cryotherapy or surgical removal.
