PATIENT QUESTION
Do I need sunscreen after laser?
SHORT ANSWER
Yes. Use broad-spectrum SPF 50 every day after any laser and reapply every 2 hours outdoors. Treated skin pigments more easily, especially in the first 4 weeks.

The detail
Mineral sunscreens are gentlest on freshly treated skin; add a hat and sunglasses when sightseeing.
