Dark mosquito spots are areas of hyperpigmentation that appear after a bite heals. These spots occur due to an inflammatory response that triggers excess melanin production. Treatment options range from topical remedies to professional procedures.
When a mosquito bites, it injects saliva that triggers an immune response. This causes inflammation, itching, and swelling. As the bite heals, the skin may produce excess melanin, leading to dark spots. People with darker skin tones are more prone to this hyperpigmentation.
Most dark spots fade within a few days to weeks. However, persistent spots may require treatment. Common options include:
The best way to avoid dark spots is to prevent bites. Use EPA-registered insect repellents containing DEET, picaridin, or oil of lemon eucalyptus. Wear long sleeves and pants in areas with high mosquito activity, especially at dawn and dusk.
Some believe that scratching bites causes dark spots. While scratching worsens inflammation, it doesn't directly cause hyperpigmentation. The darkening occurs due to melanin overproduction during healing, regardless of scratching.
