Why is it okay to expose skin to laser but not sunlight after hydroquinone?

Asked By:Awesome519692 in Sunnyvale, CA

Hydroquinone decreases the amount of melanin in skin and creates photosensitivity. Thus if exposed to sunlight, it leads to inflammation and stimulates melanin production, which can make hyperpigmentation worse. However, I was suggested to use it as pre-treatment for Fraxel dual 1550. Doesn't laser have the same affect as sunlight? How come exposing to laser after hydroquinone will not cause inflammation, stimulate melanin production, make hyperpigmentation worse? What makes the difference?
