Facial warts are tricky because the skin is delicate and the eyes are nearby. Yes, laser is actually one of the safest options for the face because it is so precise. The doctor will give your child special protective eyewear (metal goggles). For flat warts on the forehead, they often use a non-ablative laser (like pulsed dye) that doesn't cut the skin – it just zaps the blood vessels. The sensation is like a pinprick. Most clinics will apply a topical numbing cream (lidocaine) for 30-60 minutes beforehand, which makes it nearly painless. For a teenager, the procedure is very quick – maybe 5-10 minutes. There is no downtime for flat warts, just some redness that looks like a mild sunburn for a day. The warts will turn dark and flake off over 1-2 weeks. It is much less traumatic than freezing or burning with acid.
