What causes this skin condition on the forehead?

These painful and clustered blisters are caused by Herpes Zoster, also known as shingles. It is a viral infection that occurs when the varicella-zoster virus (the same virus that causes chickenpox) reactivates in the body, often due to a weakened immune system or stress.

🧠 The forehead and scalp are commonly affected when the virus follows the path of the trigeminal nerve.

📌 If you notice a similar rash, it’s important to consult a healthcare professional immediately, as early treatment with antiviral medication can help reduce symptoms and prevent complications.
