Why is sun exposure discouraged before PMU?

• A. It reduces infection risk.
• B. It reduces cost.
• C. Sun exposure can alter skin pigmentation and healing, increasing color variability and bleeding risk.
• D. It has no effect on results.

Answer: (C)

Sun exposure changes the skin’s baseline tone and how it heals, which directly affects PMU results. When the skin is tanned or sun-damaged, the pigment interacts with a different color backdrop, making the final color unpredictable and increasing the chance of uneven results across the treated area. The tanning and irritation also heighten blood flow and inflammation, which can lead to more bleeding during the procedure and affect how the pigment settles in the dermis. Additionally, sun-damaged skin heals differently and more slowly, raising the risk of crusting and color changes during healing. For these reasons, avoiding sun exposure beforehand helps ensure more predictable color outcome and a smoother healing process.
