Solar Lentigines (Sun Spots or Age Spots)
Definition: Solar lentigines, commonly known as sun spots or age spots, are flat, brown spots that appear on areas frequently exposed to the sun.
Cause: UV radiation accelerates melanin production, leading to dark spots.
Types:
- Small, freckle-like spots or larger patches that darken with more sun exposure.
Protection Before the Cause: - Consistent sunscreen use, especially on exposed areas like the face, hands, and shoulders.
- Avoid tanning beds and use hats or protective clothing when outdoors.
Cure After the Cause: - Laser therapy to target and break down pigmentation.
- Cryotherapy can freeze and lighten the spots.
- Topical creams with retinoids or alpha hydroxy acids (AHAs) to reduce pigmentation over time.
Conclusion: Solar lentigines are harmless but cosmetically undesirable. They can be treated and prevented with diligent sun protection.
